Futureal...
This is Michael that roomed with nashCrasher.com LOL down the hall from you in cleveland last year.
Just an FYI with TRC tires you have to add quite a few shims no matter what the car to get it the correct width. if you use the right axle shims it should cause no binding... I think BRP makes some that work good.
If you think about it, running a Jaco with no spacers will make your car wider than adding shims to TRC's. Jaco's tire actually protrudes out past the wheel. the tire is the same size as the TRC, but the wheel sticks out where it mounts up. Actually, associated cars are too wide if used with Jaco rims according to Roar rules.
My advice from many years of racing is... try shimming it out so that it clears a few thousandths and only put maybe one or no shims on the right side and actually measure it. I'm sure that it won't be over.
If I'm wrong... just blame it on Mr. NashCrasher aka nashrcracer LOL
