FD rear wheel sanity check for 18x12 wheels
I am contemplating the setup needed to put 335-18-30 Hoosiers on the rear of my autox FD.
The ideal backspacing is often stated at 7.5 inches, but I find that 7.25 inches provides better tire clearance of the Improved Racing trailing arms.
I know this because the current wheels are 7.5 inch backspace (18x10+50 with Hoosier 285-18-30) and a 6mm spacer is being used to provide some clearance.
Back to the 335's. Using the CCW Backspace Calculator an 18x12 wheel with 7.25 inches of backspace comes out to 18x12+19.
To you fitment guru's does, that seem correct?
How about others with 18x12 wheels, what offset/backspace are you using?

I have 18x11.5 rear +42MM offset. it comes very close to the stock rear trailing arm.
so 188MM you can go in. I am slightly stretching a 285/30/18 tire. with a 335 you will need less offset to bring the tire torwards the fender.
