paul2supra Posted April 3, 2008 Share Posted April 3, 2008 Right, had my car for about a month, and the main problem I can see with it is that it is simply too hard riding for the country roads around Oxfordshire. Also, the rear tyres (265/35/18) rub on the inside of the arches under HARD acceleration or over deeper bumps...only very slightly, but enough to grate! So, I'm thinking my first major spend (provided the engine/turbos don't go beforehand of course!) should be on a new suspension setup. Anyone recommend anything more supple than standard Jap, for fast (bumpy UK!) road use. I am highly unlikely to ever track the car...for now Also, should I consider changing the rear tyres for a size smaller, or would a different suspension/alignment setup more than likely cure that too? Any info/advice would be greatly appreciated Oh, and before someone asks, I'm not actually CERTAIN I have standard Jap spec suspension on there - haven't checked yet! From the look of the car, it doesn't seem lowered to me, and there's no mention of new springs etc with the paperwork I have for the car. Ta in advance, and apologies for going on a bit!

merckx Posted April 3, 2008 Share Posted April 3, 2008 Ask Chris Wilson on here, I'm sure he'll be able to help you out. Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 3, 2008 Share Posted April 3, 2008 I do some suitable German made Bilstein kits, starting at £1280 fitted with the geo set up. I can tailor one to suit your exact needs, several people here have them and like them. Link to comment Share on other sites More sharing options...

paul2supra Posted April 3, 2008 Author Share Posted April 3, 2008 Thanks guys and believe me, if I had that cash to spend so soon, I'd be heading Shropshire way as I type. However, having just bought the car and therefore being strapped for cash, I was thinking of going the 2nd hand route for parts, then getting professional fitting/alignment. I see Wez has some Bilsteins with RS*R springs...would they give me the kind of suppler ride I'm after? Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 3, 2008 Share Posted April 3, 2008 No, the RSR springs are a lot firmer than stock, and too low. I have some excellent used UK springs, if you teamed those with Wes's Bilsteins you'd get what I suspect you are after Link to comment Share on other sites More sharing options...
paul2supra Posted April 3, 2008 Author Share Posted April 3, 2008 Nice one Chris, let me have a ponder (and a check of the finances tomorrow!) and I may well be in touch. How much for fitting and full alignment and geometry from you? Link to comment Share on other sites More sharing options...

juanchan Posted April 3, 2008 Share Posted April 3, 2008 How would dropping the front and rear different amounts like that affect the handling? Link to comment Share on other sites More sharing options...
Homer Posted April 3, 2008 Share Posted April 3, 2008 How would dropping the front and rear different amounts like that affect the handling? In a very bad way! I had RSR 'race' springs on mine with Toyota Bilstein dampers, the handling was absolutely horrible even after a "lanceW" allignement and stock wheels/tyres fitted. I changed to Eibach springs and the car handled SO much better. Suddenly the car was driveable! However if you're after a full custom setup Chris is the man to speak to, no question.

Wez Posted April 3, 2008 Share Posted April 3, 2008 I found the RS*R alright with a CW geo setup but then I found the JIC alright and I really like my new setup Link to comment Share on other sites More sharing options...

From the look of the car, it doesn't seem lowered to me, and there's no mention of new springs etc with the paperwork I have for the car. Ta in advance, and apologies for going on a bit! Judging from your garage pics your car isn't on stock suspention I would say. I had the OEM Bilstein suspention and changed the stock 16" with 18" /35 profile tires, it almost looked like a 4x4 with the free space in the wheel arches. Yours doesn't look like that. Also, 265/35-18 is only 0,4 inches taller (diameter) than stock j-spec wheels (245/50-16), so if that 0,4 inches make your wheels rub against the aches, I would say your suspension isn't stock. I'm running a tad smaller wheels but mine is dropped by 40mm and I have no rub at all. Therefore make sure that you don't purchase a new, softer than stock suspention untill you are sure what you have on there. Link to comment Share on other sites More sharing options...
paul2supra Posted April 4, 2008 Author Share Posted April 4, 2008 Thanks for the helpful comments As I've hinted, it's a want/need versus a no cash argument! I bought the car, much like most people on here, with the intention of not really doing anything apart from the odd cosmetic addition, but can't live with that ride where I live. I hit a pothole/sinkhole (!!) the other day on a country road, and my god the vibration (more like earthquake) that ran through the steering column has now created a permanent rattle through the steering wheel... And I HATE internal rattles. Which is why finding a Supra which doesn't have the boot rubber rattle (yet) was a bonus! Re the tyres bodilx6, I suspect you're right. May just get my local mechanic bod to take a quick look and see what he recommends... Thanks again people, appreciated Link to comment Share on other sites More sharing options...

I'd be interested in understanding the implications of altering ride height/camber/toe etc. Are there any good websites/books out there that cover the basics yet are pretty technical in content? I need my suspension sorting, but until I have the funds to sort it out properly, I'd rather not hassle traders on here too much without providing them with some service at the end of it Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 4, 2008 Share Posted April 4, 2008 The * to Win series of books by Carroll Smith are superb, but a bit race biased. There are some excellent SAE papers (that you probably have to pay to get), and I have a series of newsletters by an American called Mark Ortiz that are quite good. There's an old book on chassis dynamics by Frank Costin, which may be a collectors item now, that's a bit out of date but nonetheless a classic. After that you get onto the real high end stuff that you almost certainly won't like, it's for real sad cases like me, who moan at spending more than 15 quid on shoes, but happily buy an obscure tome for 150 quid.

Thanks Chris. I'll probably have a look/search on those after the weekend £150 may be a bit steep though! Are there any websites out there too? The garrett website goes into extreme detail with regard to turbos, air flow through them etc, so I was wondering if there was a suspension equivalent?

Sharpie Posted April 4, 2008 Share Posted April 4, 2008 How about buying a second hand UK suspension and 17" stock wheels ? Link to comment Share on other sites More sharing options...
paul2supra Posted April 4, 2008 Author Share Posted April 4, 2008 personally, I wouldn't want to have to change the wheels - really like the deep dish on mine. Standard UK suspension I am tempted by though yes... As with Juanchan, money is the issue!! So finding some good condition used parts is most likely the way I'll have to go. Defo want the full alignment and geometry check done though as the last Supra I had was a mare due to a poor lowering job...again, too stiff for the roads round here. And ate tyres...at least I think that was the fault of the lowering job Link to comment Share on other sites More sharing options...
