Anyone running these? Car came with them fitted and just wondering if I should change to something more 'Porsche'?

 

Cooper is a mediocre tire at best imo. They are making a big push to get into the Ultra High Performance market, but I don't think they are worthy of your car. Check the speed ratings. I would definitely suggest you change to a better tyre.

 

Never heard of them. The name sounds hokey if that counts for anything..
