I have a staggered 275/40/20 & 315/35/20 on Style 214's and have just installed the fender flares. I was thinking of adding some spacers to make it beefier however, I don't want the wheels to stick out past the wheel wells. Based on what I've read on this forum, I was thinking of going with 10mm on the front and 25mm on the rear. Anybody with this same set up that can post some pictures.

Will this set up cause understeer? I've read that the wider the spacer, the more stress and strain it places on the driveline that was not engineered to handle it. .

Any comments or suggestions?
