We get this question or see it posted here on the automotive forums just about every day. It often stems from a desire to add disc thermal mass, or just an aesthetic upgrade, without investing in a complete brake kit (which is fine if done properly!). Unfortunately, the process of swapping the discs from one car to another isn't quite as simple as it seems, even when the new discs appear to be the 'same size' as the ones already on your car.

In our latest video we examine the critical disc dimensions that determine if the swap will work on your car vs. leaving you with some very expensive paper weights!
