Main thing with those specs is to be sure the steering arms don't hit through the whole rang of suspension motion.
On the Elise, you have to be a little careful about getting into the body work on a 15x8 front wheel.
I usually recommend a 15x7 on the front of the elise. Also the PF01 looks similar to the 949 and has more caliper room... although at 3mm, you don't need more there. The 15x7 doesn't have any issues with getting close to the steering arm, FWIW.
Elise parts makes a steering arm that uses heim joints, which will buy you a fair amount of real estate when using the 8" wheel...
Hope that helps,
So finally, '05 Elise, stock bodywork, looking for 9" rear width and 245 tyre. Will it work on track with no rubbing? What is the best offset? Nitron Street Series suspension for now, probably will switch to NTR46 soon. -2.5 camber. I choose now between 16x8 and 16x9 rim for 245/45/16 A052 tyre. Thanks!
