So what would need to be done to get these fenders to fit the wheels?

I am guessing that using a fender widening kit is one way to do it. I didn't think about using one before because I assumed that the FRP is not that flexible.

 

You would have to do 2 things.. trim the inner arch of our sweep about a 1/8 inch. Also this tire size will rub the inside corner of the front of the oem sideskirt - so a slight shave there too

And you will need to shim the front bumper/fender connection w/ a 5-8mm spacer,

Our FRP does have some inherit flex to it, not much - but enough for this amount.

 

Cool thanks for the info gives me something to think about.
