Ride is a little firm, TT supra.

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.

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

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?

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 covered that.

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

Also this one tells you how much different offsets and wheel widths will affect the clearance from the arch to the spring/damper

Hi Dnk, is there somehow an easy way to send you a photo of the car? 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.

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
