I have them already. I bought some because Hankook RS3's were on back order for like 2 months. I will be doing my first track session with these on sunday, then next weekend a 2 day autocross event. Running 255 rear /225 front.
Has anyone tried these? Have any tips? I've been driving on mine for about a week now, and they seem solid so far, excellent in wet conditions. Cant wait to try pushing them!!!
I will have a full write up once I thoroughly test them!!!
FWIW: These are on my 2010 335xi - 6AT car (w/ alpina trans flash & cobb access tuner.) I have H&R drop springs with Koni yellow adjustable struts.
