I have a 2001 cobra when i bought it it was already lowered with eibach loweing springs. i noticed it dosent have CC plates. it drives fine but i was told after a while of driving i will notice the inside of the tires wear if the alignment is off and now im starting to see my rear tires wear bad on the inside. Do i need cc plates for the front and the back beacause i have IRS? Or could i go with cheaper cc bolts to fix the problem?
