well because everyone is so helpful and this is the only forum i really know

what is a good offset for a 94 Supra TT..friend looking to buy rims and needs some help thanks guys

 

I'm moving this thread from the Black Market to the Car Talk Forum.

You could call Tire Rack and ask them.

 

Factory 16" wheels - Front 16x8 - 50mm offset, Rear - 16x9 - 50mm offset
Factory 17" wheels - Front 17x8 - 50mm offset, Rear - 17x9.5 - 50mm offset

Make sure to do what Ron A suggests though, and verify with a reputable source like Tire Rack.

It's impossible to answer your question without knowing what wheel width you want to use. If you are interested in performance and not just looks, you will want wider wheels than stock that fit wider tires and provide a balanced handling package as far as under/oversteer. Tell me what wheel widths you want and I'll tell you what offsets you need.

Since I own a '95 Supra and wanted nice 18" wheels that fit substantially wider than stock tires, I made the effort to learn this wheel stuff, so I consider myself somewhat of a Supra wheel fitment whacko. As stated above, the stock TT wheels are 17", +50mm, 8" front and 9-1/2" back.

IMO one of the first considerations is to ask "will they clear the front rotors?" ...if they do, you can move on and see if they have a good offset for the wheel width you want. MANY aftermarket wheels will not clear the Supra front rotors without a spacer, so you have to decide if you even want to run a spacer (nothing wrong with a properly engineered spacer, but I would never run one just to fit some lame ass wheel), and then adjust the allowable offset to accomodate the spacer.

As an example of what I consider good fitment without spacers (plus I didn't want to roll or cut my fenders) my 18" Veilside wheels are +45mm in 9-1/2"F and 10-1/2"R, my car is lowered a little over 1-1/4" on coilovers (which give more inside clearance than stock susp) and I have no clearance problems of any kind ever even with very hard cornering using 255/35F and 285/30R tires; I might even be able to fit 265/35F and 295/30R tires but it would be close, for sure with a fender roll I could fit them or larger. IMO since the Supra is front heavy, it can really use a wide front tire even larger than I use on the street; it's not uncommon to fit Supras with 285/30 X 18" fronts but that takes a slight roll or cut of the fender lip, then use a 315 on back.
