With the new creation of software for SS, I can't use the search function the way that I want. I only pulled three results for brakes, all current, nothing old. I can't determine what size rotors I need...300mm or 320mm. I own a FWD V50 T5, NOT the 2.4i. When I do web searches, it will list the 2.4i as 300mm and the 2.5i as the320mm. But some are saying that if your calipers look a certain way, then that determines your rotor size. Those pics contradict what the specs are saying. How can I tell without actually taking them off?
