Wheels Offset Help for 20"

[crazyinp]

I am debating of getting new set of wheels, I am sticking to 20" so not even looking at anything. Tires I plan to run are:

Front 275/35/20 MPS4S
Rear 305/30/20 MPS4S

Stock Competition Package Suspension.

I have done some search on the forum, and can't really find a good post with listing clearly what fits and issues.

Option for wheels Offset

Front:
9.5x ET22 - Aggressive might be really tight with 275
9.5x ET26 - This is based on BBS FI (discontinued) that was made for F10 M5

Rear:
10.5x ET35 - This will require spacers to make it flush, but also might be nice to tune with wider tire to the desire clearance
11x ET38 - Worry if will clear the inside of the suspension.

What do you run on your car and any issues?

Thanks!
