CTS Performance Sedan
So far, I've only installed a K&N "replacement" filter, and also changed out the stock Michelins "R" 18" P235's for Michelin P235's (18") rated AA - A. I was told these tires are good for speeds of 150+mph, and that they are far 'stickier' than the "R" rated tires (rated for 105mph I was told). For a bit over $1200.00 "all the way around" I should HOPE they'll live up to every bit of their reputation! I believe (on the tires) it says P235-AA5018-A (or the last 'A' is in another location on the sidewall). Over 50-getting senile I guess? lol...
