Message : First, just received my Brembo x-drilled & Slotted rotors and they are differnt sizes. Two are 11 inches across and two are 11 1/2 inches across. Is this normal? I know my current Powerslot rotors are all the same size but I can tell by looking at them that the rears have about 1/2 inch less contact with the pads.
: Second, just picked up these two new/used Borla mufflers for $100 each. Good deal?


Though the front are smaller in diameter, it has a larger swept area than the rear. The rear has a much larger hub and smaller swept area. If you're still confused, I have pics here. The front pistons are 4 caliper and the rear are only two; this is why you see the difference in the pad contact area (rear pads are also smaller).

Later,
