kurkjones Posted July 5, 2016 Share Posted July 5, 2016 Hi all, I currently have 18" Veilside Andrew Cooper Racing V wheels on my TT Supra, along with stock suspension setup, the ride is just too firm for my liking and I am wondering what the best thing I could do is to help soften it, I am not bothered what it costs as the car in my eyes is worth it, so wether it is coilovers, or dropping wheels sizes etc I don't mind. Just looking for advice if anyone has suffered the same. I am 235/40/18 on front, 265/35/18 on rear. I have a set of stock wheels with 225/40/16 tyres all round, but I imagine I could get some 50mm walls for them and they would still fit. Also I noticed on a recent drive out my rear wheels are rubbing on the arches but I am not wanting to disturb bodywork by rolling/flaring arches. Thanks. Kurk.

David P Posted July 5, 2016 Share Posted July 5, 2016 Stock 16" wheels with 50 profile tyres is stock size, will fit as Mr T intended and give you the best Supra ride. Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 5, 2016 Share Posted July 5, 2016 (edited) The sidewall profile isn't a mm measurement but a percentage of the tyres width, so 225/40 is 40% of 225 Surprised the rides harsh on the sizes your running 225/50/16 front and 245/45/16 rears are stock size on the GE and 235/45/17 front and 255/40/17 rear on the GTE Edited July 5, 2016 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Scott-tt Posted July 5, 2016 Share Posted July 5, 2016 Maybe have a look at suspension bushes if they're worn out this could be your problem Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted July 5, 2016 Share Posted July 5, 2016 Get Chris Wilson to build you a custom set of springs and Bilstein dampers. I've had several sets of wheels on my Supras, Inc 17's, 18's and 19's. While the 19's don't ride as well as smaller sizes, they still aren't terrible, so I would say something else is it fault here. Have any polybushes been fitted? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 5, 2016 Share Posted July 5, 2016 As David said, get a set of 16s with stock tyre sizes, enjoy a lovely ride. Quote Link to comment Share on other sites More sharing options...
kurkjones Posted July 6, 2016 Author Share Posted July 6, 2016 Stock 16" wheels with 50 profile tyres is stock size, will fit as Mr T intended and give you the best Supra ride. Very tempted David, car is practically stock anyway, just the alloys and a satnav. Anyone got reccomendations for 16" tyres? And should I stagger tyre size? (225front/245rear)?

Dnk Posted July 6, 2016 Share Posted July 6, 2016 (edited) If the wheels are rubbing then they must be way off on the offsets or have spacers fitted, the rear wheel/tyre size you using is only 3.5mm taller from the centreline than stock 17's Are you sure the car is still on stock springs Have you got any photos of it Here's a useful tyre calculator so you can see the difference different wheel tyre combos make compared to stock http://www.etyres.co.uk/how-to-change-your-tyre-size/ Also this one tells you how much different offsets and wheel widths will affect the clearance from the arch to the spring/damper http://www.willtheyfit.com/ Edited July 6, 2016 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...

I did always think the rear arches were a lot closer then the front. The car is certainly on stock bilsteins. Never looked at the springs though, and they don't look that old either to be honest so maybe they have been changed. Also I thought that all J-spec supras had 16" wheels, wether GE or GTE. And it was the UK Spec that had the 17" wheels from stock. Also do I need to have wider rear tyres? As 225/50/16 seems a nice size all round.

kurkjones Posted July 6, 2016 Author Share Posted July 6, 2016 https://www.instagram.com/supra3704/?hl=en try that link, hopefully takes you to a photo of the car. Quote Link to comment Share on other sites More sharing options...
Dnk Posted July 7, 2016 Share Posted July 7, 2016 Could do with some photos of it on level ground really and closer, if the springs look new chances are they aren't stock and more than likely there lies your problem as most aftermarket stuff is way to hard J specs came with 17's as well as 16's, it was an option as far as i'm aware, same as the larger 4 pot/2 pot calipers Quote Link to comment Share on other sites More sharing options...
Marcus GTE Posted July 7, 2016 Share Posted July 7, 2016 Hey Kurk, perhaps test fitting your stock 16's will let you know if the problem is with the suspension. It would also give you a chance to inspect the shocks for any leaks Quote Link to comment Share on other sites More sharing options...
