the power and torque (370 hp/ 387 tq)I can throw at them. The traction control only comes on if I'm WOT at low speeds over a bump or something. They can almost hold all the power in the wet as well going WOT. And I can't complain about the ride in the 255/40/18's. I got another pair when I wore the rears out; don't know what's not to like about them.
