Installed these on my new-to-me 330i sport package. I did not expect anything spectacular, but I have to say I am impressed. For the $$, they are a great buy. As good as Michelin Pilot Sports? Nope. But for 2/3rds the cost, they are a whole lot better than 2/3rds as good. They have a very good steering feel and feedback, excellent dry grip and I've never had the traction control so much as flicker in a downpour. This was a non-existent winter in NC, so I have no winter-weather report.
If I get 50k out of them, I think I'll be hard pressed to do better for the money with anything else. I already plan to get these for the wife's E320 next month.
