ok heres the deal. i am lookin at the heavy throttle 4 corner brake upgrade. i was wonderin if: 1st, does the 26mm calipers come in aluminum, 2nd, does the aluminum caliper help disapate heat better, 3rd, if so is it noticable, 4th is the 30mm rotor a BIG improvement over the 26mm. sorry for all of the questions but if there isnt a big difference i would rather save the 70 bux and use that for that big APC sticker for my windshield
