Wheel size help!

[SMGunner]

Hey all,

 

I have a 97 uk spec MKIV TT. The car was standing for quite a while and I have recently bought it back to life. Just got it mechanically sound and got it dyno'd. Is giving close to 450 at the crank and about 375 at the wheels. Now I'm in the market for some new rubber, but now I need some help figuring out whether I should stick to 17" wheels or upgrade to 18. Some help would be much appreciated.

Hello and welcome to the Club. I moved your thread to the Supra Chat section as you’ll likely get a better response here than in the technical section . 
 

With regards to your car, are you sure it’s a 97 as I though the UK spec production ended in 96.
 

Also with regards to the changing to 18’s, I’d suggest you keep your stock 17’s to the side as these are starting to fetch anything from £600-£1000 in good condition. The UK spec wheels also have a little extra bracing located on the centres, and if you do ever sell in the future then it might be best having the stock wheels. 
 

Another point to consider if you go for 18’s is checking for clearance of the 4pot larger calipers, although it’s usually down to the wheel design you choose.

It all depends if you want it to look stock? You could go down the lexus tte wheel route they always look like they should be on a supra and are 18 and a bit wider, or if you like aftermarket the world is your oyster, bigger and wider has got to be better for grip hasnt it? Im no expert tho someone might say im wrong
