I’d like to find a definitive way to measure wheel fitment without buying calipers and test fitting. I believe I have a method to do so.

If you have upgraded front calipers and non-staggered wheels, would you kindly measure the clearance between your rear wheel spokes and the rear caliper? Please include the size of any spacers you may have.

My theory is that a wheel must clear the rear caliper by X amount in order to clear an LS400 or Supra caliper up front.

If we can collect these numbers, people will be able to figure out their wheel spacing needs without too much, if any, experimenting.

Thanks y’all!

If we can get as many contributors to this as possible, we can probably get measurements of some of the most common aftermarket wheel choices.

Yeah, if you can post any measurements you can get, that’d be awesome.
