I am planning on running Michelin PS2s in 245/30/20 F and 295/25/30 R. Would it looked stretched with a 20x9 F and 20x11 R?

Thanks in advance for your help.
The proper size is 20x9 F 20x10.5 R - that is the spec we are going with for a customers M3 and recommended by HRE as well. 11s will not fit.

20x8.5 F 20x10.5 R is a big width difference and may cause unwanted understeering which might compromise the handling performance.
