Driven about 100 miles. Dry traction and cornering is awesome. My C5 has 385 horses. I find the grip when getting it on is great unlike others who have stated traction issues. A bit noisy but I typically drive with the top down, radio on and I am dead in my right ear so noise isn't an issue. I am pleased with purchase so far. Sorry I couldn't submit review without rating each category even though I have not driven in the rain and will never drive in snow.
