Going to 315 on the rear when my HREs arrive. Hope to get a bit more bite off the line. In D3 MDM yesterday for a very slight roll after car in front of me turned and got out of the way I spun a bit in 1st and 2nd kicked the rear end out pretty far. Mine is tuned however. I will be on 21x9.5 and 21x11. Will report if traction improves. I do agree with others that you just need to learn to modulate the throttle at low speeds. A nice trade off for all that glorious torque.
