i would assume that it would help but someone who runs 295 rears should chime in for that answer. I've only ran oem 275 and 305 so far out back.

Have you checked your lug nuts? Just an idea...

if he's experiencing the wobbling effect at a specific speed, then it most likely has something to do w/ the harmonics @ that speed....

i would think either toe alignment, bushings, or how the wheel(s) were counter-balanced.

It's most likely alignment, Go get that and some coils youll feel safe :)

I havent had any issues with the VDC on my 370 but it was incredibly bad on the 350 I had before
