His ISF review was one the main thing that cemented my decision

Hi, I have a brand new RR Racing Power Kit arriving soon and i'm thinking about not installing it as I might need the money for my house...boring I know. Would anyone here be interested in it? I would be selling it for what I paid for it. Obviously its right hand drive and comes with Air Intake kit and ECU tune. €3600 is what I paid and what I would be looking for. That's considerably cheaper than you would get one in direct from the USA.

If you are interested please let me know.

Hi there! I am from Northern Ireland, might be interested in this as crowd sourcing didn’t pan out. Any additional options are on this badboy?

Cheers

Sorry for the spam, but Maxton kit is on

Thinking if I need rear defuser, most of them look terrible

Getting close to finished looks

Thanks lads for all the info. My wish-list just got more expensive.

I was also looking at Bistein B6, but to be honest, I can’t fault OEM. I didn’t buy this car for comfort and I am happy how it eats all the imperfections. Weirdly enough, my wife thinks it rides softer than her Audi on Magna ride 🤔

Thanks for this - just placed an order at the dealer.

Im gathering parts for a suspension refresh although was tempted with the poly type but the fact that this bush is firstly new, and better than the ISF it should be sufficient.

 

 

Don't mind me asking, but what will you be upgrading suspension wise?

@Mantas88 From what I've read, the GSF bushes use a different compound/material than the ISF bushes and are slightly stiffer. The steering has become significantly more direct and I get no squirming, rut following and at the moment, much reduced inner tyre wear. It was definitely a worthy upgrade from my experience, handles like it should do 😈.

The reason I went for GSF bushes was to stay OEM, Lexus invest a lot of money in the design and the Japanese philosophy of constant improvement sits well with me. I didn't want Poly bushes and I didn't see the benefit in other companies offerings. If you want GSF bushes, get the 0mm offset ones. They come with a +/-20mm range. Lexus Parts Direct advised this and were great with the purchase.

Im surprised you've gotten brake fade. With the car being developed at Fuji and that hard brakiny zone after the straight, the brakes are pretty stoat. I've not come across any fade. I'm interested that's all 👀👀

That's something new I've learned. I feel stupid for buying poly Figs 90 without even considering OEM alternative. At least I will know what to get if I will hate the ride 🙂 Thank you so much for sharing this with us.

And about the brakes, well, I don't feel like I am getting sufficient bite and it really shows when warm. Or it could be just me as I don't believe that I've caused that much wear during few sends. To be honest, I decided to get new disks and pads and I will bed them in myself.  My pad choice is Ferodo DS2500 as I am familiar with then and I did loved how they performed on my BMW.

This was the state of my LCA bushes on my 2008 ISF with 70kish miles. Whilst they didn't move under MOT inspections, they did flex under load, allowing the control arm to move, I was also getting inner tyre wear, and used to squirm under spirited braking and follow ruts/grooves in the road. I swapped them for GSF bushes. It's made a world of a difference.

Thank you mate, I think you hit the nail on me head.

By the way, how does GSF bushes feel? I bet it gives much softer ride, what about the roll?

sorry to read of your misfortunes arising here ........  sincerely hope you're going to get satisfied soon .....

 ............. lucky are us mere mortals with ordinary cars that can only dream to motor at 100mph these days on normal available roads 

I remember driving around your beautiful isle a few years back and wondrous new roads in the Republic benefitting from some huge EU funding schemes ........... many of which could possibly be good for regular 100mph jaunts too ...  is your Armagh speed limit still 70mph ?

Malc

Thank you, I wouldn't call it misfortune, but it fuels my OCD and it does ruin my experience with the car.  This and the brake fade, but at least I know what to do with brakes 😄 

Glad you liked it! EU funding schemes don't reflect much on the road quality, I would even argue that the asphalt they lay in South is worse during cold and wet conditions. It all depends on the season as well. They do have nicer tractors on the road. But nicer or not - they still make same big prostate splitting potholes like here in the Norn Iron. Even the the road layout is the same and you can fly off the road even without reaching national speed limit. That's the price you have to pay to have local farming produce on your table I guess.

In Armagh we are confined to 50 mph in the city and for the most part I've not noticed the issue with the pulling for more than a year. I didn't even notice it during 1/8 runs. On the motorway I thought it was just a wind or road imperfections and I don't have luxury to drive like McGregor and I didn't care much. 

Now as we have some good weather and restrictions are gone and I have ability to fully "send" it like Yukihiko Yaguchi intended. Both in Bishopscourt track and Enniskillen airport, not to mention industrial sites I have access due to my work. But venues where you can enjoy your car to the fullest are still limited and I bet in Kent alone has more race tracks. Bike is a king here. I can't complain much as I never done it in the past and I was surprised how cheap, unrestrictive and accessible it is. I keep hearing that drift scene is absolutely disgrace here, but I can't complain with my stock diff 😄 Might change my mind after OS Giken diff.

have you ever had the lower control arm bushings replaced?

Not yet. I bought myself a set of Fig 90 LCA's after hearing that OEM bushings can cause similar issues during their life-cycle. (Only noticeable at higher speeds)

Not sure how true is that, but I've used it as excuse to improve the handling and reduce inner tyre war.

Today I've visually checked ball joints and a subframe and everything looks and sounds ok. Did another 5 OCD runs with two sets of alloys, swapping wheels and adjusting the pressure. Still. The. Same. 

I've booked in Hunter-Seeker alignment with a Kwik-fit (there are no other companies that do proper geometry checks here) as I lost a previous print-out. 

Now I am afraid I will have to work my way through all suspension elements until I will find the culprit. I've seen similar threads on US forums... Most of the times it was LCA on earlier models like mine...

Were the new tyres a mirror pair? That is were the colour bands opposite on each tyre. Tyre run-out can cause drift if not cancelled out by selecting the pairs. Not too much of an issue at normal road speeds but still noticeable.

Yes, I have another set of alloys and the car does basically the same.

Is there a camber on the road?

No, the road is perfect and flat, better than the Autobahn. I've took my wife's car an hour later day and I drove much faster with no issues.

You say you have new tyres, but has anyone checked that the pressures are correct and identical?  

Yes, first thing I did was check the pressure. It did the same with old ones as well... One of the main reasons I've changed tyres was that pull...

Is the steering wheel perfectly aligned on the steering column?  Are the nearside discs generating more friction?

I wouldn't be able to tell if wheel is perfectly aligned, but according to Lexus - it is...

Not sure about discs, braking is not affected at all. Both sides seem to be the same.

Are you left handed and/or have a dominant left eye?  Is the seat or the pedals slightly offset?

My eyesight is left dominant, but my wife's is 20/20, and it still pulls when she was driving. She notices that even more than me. Seat position should be ok. 

I am just wonder what I am missing here. I've seen some Americans and Aussies having same issue and there was lad here with same problem, but they never came back how they sorted it. 

There was some talk about the lose subframe, but surely, Lexus should have picked it before an alignment?

The alloy itself? 

No mate, I have 2 sets of alloys at the moment, does the same on both. Exactly the same feel at exact same speed. 

 

Hi there, so I have this problem when my ISF starts to pull to the left when I drive over 100 mph (private road, don't worry) and it gets progressively worse if driven faster. Good road surface, new tyres, no wind. 

I've took my car to Lexus and they checked my brake system (checked it for uneven wear, warping and etc), did the alignment and took it for a test drive. I've asked them about caster/camber, they said it's all green.

The issue still remains. 

Any ideas what could I check that could influence this behaviour? 

Interested in headers as I was waiting for UK manufactured ones for ages. 

The problem is... I live in Northern Ireland and I am still looking for garage to fit them, it's not an easy task that can be handled by some random garage.

I will get in touch if all goes well.

Morning all, I am looking into the possibility of having a duck bill bootlid made for my ISF (think along the lines of the E36 M3 CSL) something subtle that is actually part of the bootlid rather than stuck on, likely to be available in GRP or full carbon.

Are any of you guys interested?

 

 

Sorry to resurrect this old topic, but did you find one? I was also looking at the same and decided to go with stuck on..

Not sure about being subtle, but check this

I would love that, but I am in Northern Ireland and I am still recovering from some brain damage 😄 

I wish we had a meet here, UK/Ireland. Probably could get 4 cars at least.

Thank you everyone for replies, I really appreciate it!

Now I want it more than before... But as mentioned, finding one is a chore. I am also based in Northern Ireland so I will be shipping it and all those logistics are pain in the bum. I guess I will need to snipe it when right one comes around. I will be keeping IS F and I don't think I will sell it at all too. I love it as well 🙂
 

Hey guys.

I drive IS F and there's literally nothing wrong with my car. I love it. But I do love GS F as well. 

Now the question is - who had both of them, how different does GS F drive and feel? I know it's much larger car. 

Can anyone please talk me out of it as even my lady is for it. 🤣
 

Was nice and sunny today.

what size/offset are the rears?

19x9,5 ET35 - 255/35 tyres
 

Just an update for those interested in these wheels - rear bastards do rub every time I go over the bumps. I only noticed that during my trip to Ireland.

Looks nice. How are you finding the new tyres?

It's bit too early to come up with a conclusion. I only did 180 miles on them. At the moment tyres feel very stiff and not too grippy. Over few weeks I should break them in.

Took it to Dublin today. 

This car brings so much joy to me... I am very lucky that I'm still able to drive it 😄

I want to say thanks to everyone here.

I finally got JR11 from Poland and fitted them with Goodyear F1 Asymmetric 5.

No rubbing, quite a stiff ride to be honest.

Ahh, the 20" concaves and lowering may have contributed to the reduced ride quality on the BMW! 🤣

Thanks for the very kind offer. I'll maybe take you up on that once the restrictions are eased. My preference is an earlier car, but only if the ride isn't unbearably stiff. If yours is stock, it will be exactly the kind of comparison I'm looking for.

Fair play on running an MR2 twin turbo as a daily for a year. I can imagine the handling is quite 'interesting' as soon as frost or snow hits the ground! 😬

Handling of MR2 was 'interesting' every time I had to enter a bend or a corner. I was aware about the snap-oversteer that plagues mid-engine cars, but it's a thing you need to experience to learn how to avoid/get out of it. My father had MK1 and told me that in his days MR2 was a like a street bike on 4 wheels - only the slowpokes survived.👴
