Hello everyone, did someone maybe know or put the ISF forged rims (RV737) on the latest GS? I have an F-Sport trim with 9J19" ET60 on the rear axle and the ISF rims are 9J19" ET55. This 5mm are forcing me to think. front axle is identical on ISF and GS I mean this exact wheels: https://allegro.pl/oferta/felgi-19-oryginalne-lexus-is-f-2007-2014-idealne-11178997078 Thanks for any clues.

Hi all, apologies as I'm sure this has been discussed before but I couldnt find the answer I was after by searching the forum. If you can point me to a thread then please do! I am in the market to buy an ISF after my RX7 gets a good enough offer on it. I have been examining the available choice and there is quite a stark difference in price between a facelift and the non-facelift variants, usually about 5k for similar miles. There are obviously more changes between pre and post facelift than just the diff, but most of them can be easily rectified with a mod or two (headlights, bluetooth etc). Is the torsen differential an essential purchase for those who give it a hoon every now and again? How effective is the e-diff in the pre-facelift model, is it very noticable in lower gears and launches, or does it behave roughly the same? I have no intent on taking it to the track, but those moments you give it some beans at a light I wouldnt want to be shown up by something purely because I couldnt put the power down with no proper diff. So how good is the e-diff? Or should I just bite the bullet and find a post-facelift. Another option would be swapping in a torsen diff further down the line, but I understand this can cost a lot on the second-hand market, if I can find one at all. Thanks

Hi, I'm after a set of ISF Alloys, like the attached. Based in Fermanagh but will be able to collect from any location. Hit me up with offers Thanks

Hey guys, I hope you are well? I made a video on things you didn't (or some of you may) know about the Lexus IS F. I thought some of you might appreciate a V8 distraction during this quarantine time? Ps this is my friend's 2013 IS F and I love the Ultrasonic blue colour! Stay safe, Thomas

Hi guys. I'm new to the page but I don't think my car is! FD13BWM is my car (was once "M3 WTF" how apt), and wondered if anyone knew what it's been up to? If not say hi anyway! I'm in Bridgend, South Wales. Cheers guys I'm loving my F been wanting one for a while.

Hello, new to the site, joining in hopes to open avenues with vendors on the never ending quest to improve the car, pick at brains of the tenure F owners. I’m former US Air Force, med retired, visited Mildenhall many moons ago. Current contracting all over, primarily Japan. I have an 09 ISF, full adjustable rear suspension, Hardrace, HKS coilovers, waiting on supernow and SIKKY braces bushings endlinks etc. starfire Pearl, 19x9” front 10” rear Rays G25, cwest aero. RR tune waiting to find headers for a right drive and making my own header back. 60k on the clock, first Lexus ever, transitioned from old yota drift missles, and STI/EVO cars. Started off like any good yank with some ugly cheap interior muscle cars. Was a BMW tech/enthusiast and now settling in with the Lexus since manuals are done deal after years of breaking my body down. Couldn’t be more excited and impressed with the platform. Always interested in learning about other regional car scenes and how people live and operate in life generally not just cars. Hoping to network and source parts as well as find cool stuff for my new found Lexus brethren.

Folks New to the Lexus forums, having only recently bought a 2015 RCF. Starting to get used to the car but have noticed that the back end is light and wondered how it copes with the winter roads given it has a lot of weight up front and a lot of torque in the back end. Are winter tyres a good investment with the RCF, any views would be appreciated. Richard

Hi all, My car recently ticked over 91k miles and needed a full service, last service was August last year at 83k. As it was at 91k I booked the car in for a 100k Major service with Lexus Plymouth. I understand a large service like this is only done at 60k miles and 100k miles, please correct me if im wrong, Just thought I'd add a post on costs and what was carried out if anyone is getting near that service point in their cars life. I purchased 2 new Pirelli P Zeros for the front wheels a couple of months ago as the inner wall had the dreaded tyre wear, middle and outside were like new 😞 I got a great deal from Oponeo.co.uk I saved them for the service so Lexus could fit them (which they kindly did free of charge). Lexus did all the usual full service items, changed the Oil, brake fluid, engine coolant, screen wash, all filters screen wash, checked for recalls, plugged the engine in the computer etc etc, Also a full visual inspection, they took off, checked and re-tourqed all 4 wheels, tyre pressures, checked control arms brakes, suspension, literally every nut and bolt of the car was looked over and tightened. There was nothing wrong with the feel of the car before the service but it honestly felt like new when I picked it up, felt solid. I had a rubbing noise from the passenger wheel in the week building up to the service, they checked it out and found the heat shield had slightly bent and was rubbing, all fixed for free and no more noise. It was a bit of a relief as I've only owned the car since April so this was it first proper full inspection by Lexus under my ownership, they confirmed the car is in great condition and had been well looked after. There were only 3 things to sort at a later date, air conditioning needs regassing which I'm not fussed about, with the Hayward and Scott exhaust burbling im more of a window down kinda guy. Heat sheild above the exhaust was ripping a bit and may need replacing, and lastly 3 clamps on the exhaust were leaking slightly so will need replacing, as it was a Hayward and Scott exhaust they didn't have the correct clamps so wouldn't touch it. All in it cost £595, Money well spent IMO, I am curious as to what a simular service would be for a M3 or C63, RS4 etc. The customer service and work carried out at Lexus Plymouth was first class, added benefit of it being a 5 mintue walk from my house it's a relief to have a garage like that so close. Another stamp in the service book and a warm fuzzy feeling the car is in great condition. Apologies for the long read Cheers Ian

My RC-F Carbon is arriving on the 17th, I have a couple of quotes from Confused and Admiral of c.£1,000 which is fine...but as all you guys have lived through numerous renewals and quotes I would be interested to know who you find to be cheapest. For comparison purposed I'm 40, a company director, zero points, 5 yrs no claims.

Ok, so getting back into the ISF after the recent snow brought up a good selection of dashboard warning lights. Notably, PCS, ABS, AFS (flashing) and finally Slip Indicator (?). Snow wasn't that bad around us but car was left untouched during that short period. In the process of arranging to get these checked but just checking if anyone has experienced this combo before - I guess some sensor failure (maybe damp)? Drives ok - or at least it did on v.short journey home where I've left it. Andy PS: My other car is a Skoda Citigo, completely the other end of the scale but spending a little time back in it makes me realise what good little runabouts they are.

I reckon this one will get divided views! I know there are a lot of purists on here but as a long term modifier of all things automotive it was only a matter of time before the ISF came under the knife. Fear not Big Rat, all original parts have been kept for prosperity (and the next owner)! Not the best weather for a photo shoot but anything to avoid wrapping presents! So, here is my 2009 ISF with the following mods, some close ups of the most recent additions will follow; Rear High Level Roof-line Spoiler in Body Colour, H&S Cat Back Exhaust with X-Pipe, HPS Intake Elbow, K&N Drop-In Filter, Tein H-Tech Springs (Only the Fronts fitted giving a 25mm drop - front and rear tyre gap now matches ), H&R Spacers Front and Rear (15mm widened track each side), Tom's Carbon Fibre Rear Diffuser, Novel Carbon Fibre Duct Panels, Black Plasti-Dipped Front Main Grill. I've also got the CF Fog Light Trims, Auto-Technic CF Front Splitters and a Wald Style Rear Spoiler (in Body Colour) to go on in Mid-Jan when I get the front bumper resprayed. I'll also be relocating the front number plate then (controversial!). Enjoy! (or maybe despise.... the choice is yours!)

Note to moderator- please leave this in the ISF forum, it’s more likely to be of interest to ISF owners than GS owners. After one year running a GSF, I thought you might be interested in my experiences compared to my previous early ISF. First thing to say is that running a high performance car like this makes no sense at all in the suburban environment that I live in. It drinks petrol in traffic, it’s big to park and you cannot use the power. However, I don’t care about all that, I love driving it, I love the noise and I’ll continue until the eco mentailists or the mayor makes it impossible. I’ve always loved muscle cars and this is definitely a muscle car. In summary I’d say it is an evolution of the ISF, it rides better than my 2008 ISF, it feels more planted and agile despite its size, and it has a slightly more bubbly exhaust note, but it still retains all the other ISF traits such as build quality that we are all familiar with. It is more relaxing to drive than the ISF due to the better ride. A couple of longish trips have been made with no driver fatigue whatsoever. It has of course been absolutely reliable, (but I haven’t yet done that many miles). Update after year 2. One glitch was a broken windscreen which took about 3 weeks to sort because Lexus couldn’t supply one right away. I hope this is not a flag that parts are going to be difficult because Lexus have only sold about 50 of these and their bean counters won’t be happy about stocking spares that might be slow moving. To be fair they did loan me a car for 2 of the 3 weeks. The much criticised mouse controller for the sat nav and audio is fine, it just takes getting used to and the sat nav now accepts full postcodes. The info display on the panel is a lot simpler than it looks, again just need to get used to it. Has a lot more information such as g forces, but it no longer has a battery voltage display! The car complains if the battery voltage is getting low though. The car has a lane departure warning system which can be set up to correct the steering if you wander out of lane. This has been turned off. The car is not driving, I am. It has speed limit detection which displays the speed limit on the dash and the HUD. The only thing is that some of the road signs near where I live confuse it and it displays “unusual” speed limits. Don’t think the magistrate would accept that the car told me the limit was 90, when it was really 40. The headlights are pretty good but possibly not quite as good as the ISF. The 4 driving modes can be summed up: Economy and normal – no perceptible difference in feel or fuel consumption between these, feels slightly softer than the ISF in normal driving. Gearbox sometimes reluctant to change down when you boot it. Sport – similar to the Sport mode on the ISF. Gearbox more responsive. Nicer to drive in this mode. Fuel consumption similar to Normal and possibly a bit better providing you can actually drive the car rather than sitting in queues. Sport + -Don’t select this in the wet, there’ll be a lot of traction control warnings at even quite modest throttle inputs. Hangs on to lower gears for some time after you’ve finished accelerating. Very entertaining in the dry though and much easier to get the engine into the 3500rpm+ range. This is the mode that reveals the true brute character of the car, (when you get a chance to use it). I can’t say what Sport+ does to fuel consumption as the opportunities to use it for any distance haven’t been there. Haven’t tried the diff setting options yet. The finish on the car is superb, people have commented that even when it is obviously dirty it still shines. My car was a demonstrator so it may have been coated. Costs – Service due next week, but for some reason Lexus think it’s OK to put a £100 premium on the servicing costs over the ISF. Insurance – you have to shop around. Most companies load the premium because of the value of the car. I managed to get cover for about the same as the old ISF but had to accept a £750 excess which I covered for another £60. Not so good points: No spare and you can’t buy one in this country even though the handbook mentions a space saver. I don’t like the idea of a can of goo which will render the tyre unrepairable and probably screw up the TPMS sensors. Does anyone have any ideas where a spare can be obtained? The boot is enormous but the rear seats still don’t fold. Why?? No passenger front seat lumbar adjustment – penny pinching on a £72K car! But the wife thinks the seats are OK! Possible costs of brake pads and discs – horrendous costs have been mentioned on the forum for RCF items and the GSF uses the same parts. Non-Lexus parts seem to be unobtainable in the UK at the moment. Not an immediate problem but one that needs to be kept under review. If anybody knows where to get RCF/GSF pads and discs from somewhere other than Lexus UK, please shout. Graham

So after being one of those 'lurkers' for the past few weeks and reading past threads I feel I'm up to scratch on the ownership experience of an ISF and all the usual things associated with owning your first. Anyone know about this grey example on AT https://www.autotrader.co.uk/classified/advert/201710250637403?advertising-location=at_cars&transmission=Automatic&postcode=ox266eq&model=IS F&page=1&make=LEXUS&onesearchad=Used&onesearchad=Nearly New&onesearchad=New I know that as there only 200 or so in the UK that there's a chance one if you will know something about this one? Certainly as there are a couple of members from the south West. Wiltshire isn't officially south west in my book but worth a shot.

Hi ISF owners, I was wondering if anyone with a 7-9 year old ISF has recently had a rolling road BHP test? If yes what was your BHP? Was that taken from the crank/flywheel or the wheel/tire? Ive just had a new short block replaced along with a complete clean and rebuild (paid for by Lexus under my extended warranty 12k cost!!) after my engine was losing loads of oil but upon having a BHP test I am only getting 365 at the crank which is nearly 55 BHP down on what it should be. However Lexus are telling me that is about right for a 8 year old ISF so Im looking to see what others are getting from a 7-9 year old ISF (standard build - i.e. no enhancements)? Thanks Aaron

Hello peeps. So my replacement battery i had was a Toyota Optifit which tbh im not happy with. Been 18months and its struggling as the days get colder. I bought a Ctek charger which charged it and it was ok for a day and then when i measured it across the terminals i was only getting 11.8v Can someone who has the original factory fitted battery take a pic for me and if they can find out the spec and part number from the battery please? Cheers

Need some help and advice gents. So I've had enough of my OEM Bridgestones and wanted to change to the Michelin PS4s tyres all round. I thought I might as well upgrade the sizes from OEM to 245/35/19 fronts and 275/30/19 rears. Got to Costco today after ordering them a few days ago only to be told they refuse to fit them as the are not the manufactures recommended size and it will invalidate your insurance. 1st I've heard something like this as I'm sticking to the correct load and speed rating. Any advice please? You guys who have upgraded the size told your insurance company?

Got a reminder on Facebook today that I picked my ISF up a year ago today. She replaced an E90 335i which I also had for a year. Summary of ownership below... BMW 335i M Sport - MY2007 - 40k miles Failures... 2 x turbos 2 x turbo actuators 1 x Lambda sensor 1 x High Pressure Fuel Pump 6 x Injectors 1 x major oil leak Then on to Lexus ISF - MY2008 - 50k miles Failures... Zero In case of tempting fate I have just renewed my Lexus warranty for 2 years. Money well spent? ;-)

Morning Team LOC. Plenty of threads on this but I just came across something that excited me a little and thought it may help our small community. I replaced my brakes all round some time ago and recall the trauma of finding original Brambo front discs (or discs at all for that matter) for the ISF. Well I just ordered another two sets of discs for my race car for the upcoming season and randomly thought i would take a punt and see if they made discs for the ISF. Result result they do! I can recommend these chaps and endorse the quality of their discs having proven them in racing for at least 3 seasons. For info my race discs exceed 800 deg C, never had a warp, crack or any concern with them so for the relatively sedate road puposes you cant go wrong. Anyway link and screen shot. When the time comes I know where I'll be heading. http://www.mtecbrakes.com/brake-discs/lexus/is-f-08-13/is-f-5-0-02-08-12-13.html

Hi I'm on the search for a full set of isf wheels, good condition genuine ones with tyres preferred but would consider other options. Thanks Dan

Hi all, I don't contribute often to this forum but I do read it every day. I've seen a few posts where members are asking about various cars in dealers. I traded my ISF in today against a GSF and the Lexus dealer told me it would be going to the auctions as it was too old for their stock, so it will be appearing in a dealers sometime soon. Don't know where but if GU08VSN turns up on a forecourt it was mine. I've had this car for 4 and a half years and enjoyed every minute of it. This is a good car and I would have kept it for ever if a chance to buy a nearly new GSF at a substantial discount hadn't turned up. 30,000 miles and all it cost me apart from servicing was 3 tyres and some brake pads and discs. Only 2 things went wrong, the idler pulley on the drive belt and a seized caliper, both paid for by Lexus' warranty. It has full Lexus SH and about 75K on the clock so if it turns up with less than this someone's been at it. It's also going to need new front discs fairly soon as the thickness is near the minimum. I do have the new discs as I intended to do them later this year, so I'll probably put them on eBay. Watch out for this car, it's been loved .
