I purchased the tire based on review of Car and Driver and the ability to swap tires from left to right and vise versa. I have staggered set up on my C230 235/35/19 front and 265/30/19 on the back. The back wore out despite swapping once at 15,000 miles (also because I tuned to car to lean on the rear more for more balance handling and also due to negative camber from lowering the car. The front is still running after 23,000.
Initial response is generally positive. First thing I noticed was the quietness and ride smoothness compared to Falken 952 I replaced. The handlinig seemed to be more balanced as the front is able to bite more. Highway stability is excellent and so is the corning stability. Handling the rain is fine but I could not get definite feedback as tread was down by the time rain season hits. The only thing was the steering responce and feedback is a bit slow. Overall, I really like the handling as it made the car more neutral in handling (but that could vary between cars) and I was able to extend the use of tire by swapping them. Not too max performance tires are made now a days as asymetrical (same pattern left and right) so my choices were limited because of my staggered set up. These tires were also the cheapest max performance tires I could find and even came with 60 dollar rebate. You won't be dissapointed unless you are looking for something for track use that demand more accurate steering feedback.
My driving style is mix as easy going during commute and traffic to aggressive on open winding road so your mileage may vary.
