I got new rear tires, potenza sport which go head to head with michelin ps4 etc. Huge improvement off the line. But I noticed I get esp braking the right rear wheel on right turns occasionally.

Front tires are a different potenza which I didn't like very much but are supposed to be very good. All four tires are oem sizes on oem rims with stock open diff.

Thomas,
My brother has a Kleeman SLK55 and had the same problem. The Dealer told him it was because he had two different types of tires. He switched the fronts out with the same type tires as the rear, problem solved. Just my 02.

Thanks, I figured this would be the most likely solution. A bit odd with easy driving but I guess the system is quite sensitive.
