2008 Lexus iSF suspension shocks cars is on 49k miles , no knocks or bangs , no leaking or any other issues some surface rust that doesnt affect nothing reason for sale upgraded to Coilovers looking for around £400 collected from Swindon open to offers as just need them gone

I’ve seen these fitted when coilovers have been added …. https://www.screwfix.com/p/floplast-push-fit-socket-plug-grey-110mm/18082

Just saw this after a quick search - coil over conversion kit for RX450h https://www.fittedvisions.com/products/fv-suspension-coilovers-08-15-lexus-rx450h Look like a £1K ish - may be some tax. I did this years ago on a LS430 when the air suspension bags started leaking and the ride height sensors wore out. Rockauto may have the parts a lot cheaper that Lexus UK will sell them if you want to fix your existing suspension. Good luck Bren

Thanks Vlad. He's free to do what he wants haha.. It's just advice as I don't know how much experience he has. I wish someone told me about cheap parts & "expensive" parts when I was younger. People often think that cheap wheels or coilovers are the same as branded ones, you just don't have to pay extra for the name. It's not always true, especially when it comes to suspension or wheels. The two things that are under the most amount of stress.. This is a forum, we should share the knowledge we have. If you choose to listen or not is up to you 😅 Also just to clarify, not saying BC Coils are on the same level as eBay chinesium. Both TEIN and BC Racing coilovers are entry level budget coilovers but Teins are more suited for the streets. BC would perform better on the track.

After almost buying an IS a few years back, a couple of cars between, I now have one! I’ve had 2 Celica’s in the past so really wanted to get back to some Japanese reliability after 2 years owning a terrible Volvo. I now own an Auto 2006 IS250 SE-L with 155,000 miles. I’ve owned it since October and it’s been fantastic so far. I wasn’t put off by the millage as the car came with FSH and only one owner, previous guy had it from 10,000 miles. I’ve got some mods I’d like to do in the coming year, it came with a custom stainless back box system fortunately, which sounds lovely & a K&N Filter. Mods I have in mind to do: - Tein or BC Coilovers - GS450/IS350 Brake upgrade - Bola or similar designed alloys - Possibly a custom mid pipe - Polybush ARB bushes - Boot Duck tail spoiler But first of all I’ve been working away doing some service items. So far I’ve done: - Engine Oil & Oil Filter - Diff Oil - Spark Plugs and new gaskets for the inlet, cleaned the throttle body at the same time - Lower control arm bushes - LED side lights. Parts I have but yet to do: - Full transmission service kit, filter and new gaskets etc - Drop Links - Front, Rear & Hand/foot Brake service I plan to keep the car for a good while so want to make sure it’ll get me to 200,000 miles and more! a few shots below of Car & some of the work done so far! New bushes ordered from Japan New side lights, also had the chrome grille surround off to spray black. Hopefully I’ll keep the updates coming.

Stew did a nice creative thing with the coilovers. He fit some 3 to 4" circular hifi speaker covers over the carpet area cut to fit the coilovers. I'll post a pic when I get a chance. They actually do just look like an extension to the sound system. Very neat really.

I guess the coilovers can be dialed for max comfort rather than max performance? Best price I can find. £929 https://www.kamracing.co.uk/meisterr-zetacrd-coilover-lexus-sc430-uzz40-2001-to-2010.html

While you are here Neil. Meister coilovers seem to actually be a cheaper alternative to replacing all four corners with new Lexus shocks and springs. Might as well replace the 16 year old springs if I am doing the shocks. Do you need to cut little holes in the carpet for the rear ones? If so how do you pinpoint where to cut the hole?

I have a 2010 ISF that I’m considering selling due to lack of use, but it’s difficult valuing it due to it being such a small market. 2010, USB, 89k miles, full history, new brakes and tyres, 11months MOT, Tein coilovers, H&S exhaust and loads of little jobs done on it. Ones for sale on Autotrader don’t seem to be selling at all?

You can bounce the back of the car to see how it reacts but how does it drive? That's the key. Almost everyone likes Meister. They are better than the originals especially old originals and they are adjustable but there are alternatives. If the standard suspension on the SC was the same as it is in the GS3 is would have been fine but Lexus set it up to be quite soft so the handling is biased that way and therefore compromised. From memory the aftermarket coilovers improved the ride and handling significantly but my addition of very wide low profiles take that comfort gain away. Just replaced the fronts on the GS with original Lexus units and they were about £360 each.

Meisters. Would there be two types for Mk1 and Mk 2 car? Seems cost of coilovers is less than standard shocks and springs?

Recently? New gear knob, new center caps, coilovers, new rear LCAs + bolts, RC-F LCA bushings on the front, 6.3l of Castrol's finest and a genuine filter to boot, as well as a new N/S washer jet.

In the process of importing a ISF to the UK. After looking around a while I've settled for a Pearl White 2013 model. Its got a cat back exhaust, coilovers and riding on RCF alloys which really fill the arches. Its already on a ship a fifth of its way here. Already exited 😁 Pics to follow 😉

My observations. Coilovers! Race chip?! Outstanding recall, so has not seen a main dealer in a wee while. Otherwise ticks boxes.

If you like that colour combination there is this for a bit more money, but lacking a couple of the other cars bits, coilovers etc. The Car Warehouse - A different kind of company, a different kind of car<br/><br/>

“ reasonableness “ surely pertains OEM type / style replacements all ok whatever the make ….. surely changing air to coilovers ask specifically …… that wouldn’t affect the car mode or structure BUT I would ask to clarify Vide My personal issue and insurers tell me it’s OK ……. 16” wheels in substitute for the original 15” on my 91 Ls400 …… hopefully sense prevails but if in doubt simply ask them !

I have just spent 3 hours in the company of your 2001 SC 430. It's still looking very sharp. In general, a well sorted car.Being Sorned I could not get a run in it, but Neil the current owner seems well pleased with the performance. Apart from the expected couple of things that any car will get if it's driven it is quite immaculate and it is still on coilovers ! Pleasure to have been able to give it a lengthy lookover.

Mines an Auto, would usually go for a manual but the tax cost was a killer. It's a lovely car, has the bonus of having a stainless custom backbox on it already. Guy I got it from had it from 10,000 miles, it now has 153,000! Currently collecting service items to crack on with, I've already done the engine oil, found it had a K&N filter in it when I went to change the air filter, always a bonus. Going to give the trans fluid a full change and change the filter, then do the diff oil. Long term would be a full suspension overhaul with some Hardrace control arm bushes, Tein coilovers, and since reading your thread some 350z alloys! I've been after a different set for mine as the standard 17's are a bit knackered. The 350's Rays look nice, and not stupidly expensive on FB Marketplace.

Like @Linas.P said, tyres make the biggest difference generally speaking. @McShmoopy I agree, stretched tyres are more comfy than regular tyres due to the angle of the sidewall, it flexes more. If your tyres aren't stretched, you'll find that the sidewall is pretty much straight, which is what makes it stiffer (that's why runflats are notoriously hard - reinforced sidewalls). It's not the best for absolute performance due to the sidewall flex but you will never notice this unless you're on the track. And yeah, if it's moderately stretched, say 225s on 9.5" wheels, or even similar to Linas's setup that I've seen in person, you want to run at least 44PSI (depending on how heavy the car, you might want more - like Linas) to avoid de-beading but this would occur when the tyre is extremely stressed - drifting, racing around. Normal use won't face this issue if you have say extra 8-10PSI more than what it says on the plaque in your door shut. As for coilovers. I haven't had the pleasure of driving on HKS coilovers in a Lexus. I tried them on a JZX90 and some other cars but it doesn't matter - it's not comparable if it's a different car. Look at technical specs of the coilovers you want to buy. TEIN Flex Z (damping adjustable and cost £804 new) I had on my black IS250 were very comfortable. The ride quality was better in every way than my tired stock suspension on IS250 SE after 130k miles. Comfort was retained, body roll was reduced (a little bit) and handling was improved massively. The standard spring rates of those coilovers are 8KG on front & rear. And that's what it all comes down to. Spring rates make the ride harsher. Dampers make a difference too, but it's mainly the spring. And it can't be one without the other. It works in harmony. For example my BC Racing coilovers I have now are 12kg & 14kg spring rates. It's not a massive difference in terms of comfort, but it's definitely noticeable. TEINs were A LOT nicer to drive on, perhaps not as stiff but for 98% of driving it's way better. People make mistakes by buying lowering springs to get the car a little lower, but you're putting a shorter and therefore stiffer spring on a stock strut that works in a different pace than your new spring resulting in a harsh ride. 3 of my mates went for the Flex Zs and everyone is very happy. When I first gave them a ride in the car, they couldn't believe how soft and comfortable it was. And with adjustable damping, you can make the car softer than factory. Bear in mind, the stroke is shorter, so you can't be going over speed bumps at 30mph anymore because you will bottom out, but otherwise there are no drawbacks in my opinion.

To be fair I paid the full 10k for this ,because some of your spend had already been done to my satisfaction. Like the exhaust, majority of brakes and suspension (coilovers). Also satisfied with the current audio and exactly how good it is I don't know, because I am virtually deaf in one ear and not that good in the other. Stew is probably thinking he had not noticed, but I lip read well as I have been doing it for most of my life. Anyway the Audio is good enough for me. So, my rough guesstimate on buying this was that I would spend circa 10 to 15k doing mechanical/structural stuff, now and future, with the rest getting the leatherwork and body right on point including some dream Alloys at some point. I was inspired by Nigel? doing his leather seats so I am determined to have a go at that as it's my kind of thing to do. Likewise I am going to take the finish on the bodywork right back and rebuild it. Hence, I will have to spend on an erectable outside 'tent' so I can work out of the weather. Depending how I do with that work I might underspend, or just decide it's not good enough and pay for it to be redone. At the end of it, at my age I could have gone out and spent 20 to 30k buying something a couple of years old with not much mileage and been bored to tears, but if I was going to do that then I don't think I would have waited since I sold my last car in 2016 to do it. My wife has been teasing me to buy a new Aston Martin for years, but I wanted a car that 'grabbed' me and motivated me to create a project with it. The SC 430 is that car. Personally I don't care about resale issues I will leave that to my wife/daughter to determine. I am here for a Good Time not a Long Time and the car is a part of that.

Rear dampers on my car are made by Tokico, with 48530-53280 part number. Fronts are Tokico too, but I don't know the part numbers of those. As for coilovers, the only ones I've seen for an IS that supposedly retain a comfortable ride, are Hipermax III CLX by HKS.

That is good point - aftermarket coilovers almost always going to be less comfortable "out of the box". What they call "comfortable" basically translates into - better road handling and less body roll with just 20% comfort penalty, so it is relative - they are comfortable compared to more aggressive coilovers, but they still less comfortable than stock . To really get them to be more comfortable you need ones custom build for you, basically choosing spring rates everything yourself, a lot of trial and error, it is pretty much rocket science at this point. As well note - the less comfort may be somewhat related to age/wear, not necessarily F-Sport parts. For example when worn bushes start transmitting vibrations into the car body is not because they are too hard, but just because they worn out. So simply refreshing the rubber parts in particular can improve the ride. It won't be softer, but it will be less road noise and vibration.

Hi everyone I was wanting to get some ideas and thoughts on how to improve the ride quality of my IS250, being an f sport the ride was quite firm but this was majorly improved with my continental eco contact tyres, I recently have tried out a SE-L 250 and the ride quality was vastly superior, is it worth trying to get a hold of stock IS250 suspension used or getting after market coilovers, I have heard the springs used in the f sport suspension are very stiff so could changing those make a difference?

How does the handling compare to the coilovers? I take it that compliance is better? Glad you got it sorted.

Hi Yea Tein will be okay, people tend to normally go for conventional shocks from Rockauto or BC coilovers. Have you also fitted a separate gearbox cooler? If not, I'd suggest you do it as the ls430 suffer from gearbox failure due to coolant leaking from the radiator into the gearbox
