they do seem to follow the crown more.....but in my case, it's partly because of the toe-in that steve set for me when we put my springs/struts on.
i'm sure that compared to stock Eagle RSA's, the Kumho's will def. grip more.
i've had the kumho's for like 5-6 months. i've never spun the wheels at all, except for the loss of traction on hard cornering. but that's mainly due to having an automatic......no smoky burnouts for me
with the lack of power getting to the wheels, i'm forced to drive semi-conservatively. so i'm just now being able to tell the first signs of wear on the fronts. reminds me, i need to go out and rotate those things sometime.
but, others may have totally diff. experiences with the 711's if they peel out alot.
