Eaton's 818C Build - Power Window Modifications

[Mark Eaton]

I have the FFR upgrade wheels and am wondering if anybody used something different for tire size than the FFR recommended, 215/40/17 Front and
255/35/18 Rear . I have a feeling that front tire is going to rub. The OEM wheels and tires were rubbing while we were go-karting...

Mark,
We are using these wheels and the recommended tires, and they do not rub. They have the proper offset versus the OEM wheels, so as long as you have tucked away the coolant hoses, and followed the "rough alignment specs" for the UCA's it should be fine. Now...we are having rubbing problems with the left rear tire after final assembly...and paint. Still working on that one.

The fronts are particularly difficult as you need a relatively short tire < 24" tall. The rears are much more forgiving. I have used 215/40/17's and 225/40/17 Hoosier's on the front with no rubbing. On the rear I have used all the way up to 275/35/18's, although those are very tight!

No matter what tires you run you will need to use steering restrictors to limit the total lock to lock travel as the tire will rub on the inside splash shield at the limits of travel if not.
