I am also installing a TT Front Brake Kit. What offset do your wheels need to be to fit the Supra BBK?

 

Dunno what the exact specs ya need are... but my front wheels are 19x8.5 +35, and i had to shave about 1.5mm off of the corners of the caliper. I now have .020ish clearance between the caliper and the wheel spoke (woohoo feeler gauges)...

 

Thanks!

 

ofset plays a role, but the style of rim you have also has to be considered.

 

What style works the best???

 

high disc i think is what they are called.
if your rims are not going to clear BBK you can always stick spacers, push them out, create more room. However, since you already have a lower offset wheel over stock, depending how much clearence you need to clear the BBK, adding spacers might give you too much lower offset. if that happends, then your wheel will be past the fender.
i think it's worth a shoot though.
