The car definitely benefits greatly from having more rear rubber when you power out of corners.
My philosophy has always been that you add traction
to the axle that needs it
, not the other way around... until you reach a certain limit of course. For understeer, you would add rubber to the front axle, not remove traction from the rear axle.
There is a reason why BMW went with staggered, 8.5/9.5 stock M3, 9/10 ZCP/GTS, 9.5/10 GT4.
Here's my set up FYI.
18x9.5 / 18x10.5
265/35/18 / 295/30/18
