I have tracked 3 times now in the ZRE with stock brake rotors, pads and calipers. Still fine to this day. Le.vinh.zr is awaiting his order of Dixon (JDM brand) slotted rotors + calipers + brake pads = mass braking sexytime. Be aware of the price though Our standard brakes are fine for street use and even so on track. But if your looking for an upgrade, i'd go Fronts Slotted Rotors and upgrade pads all round. No need to bother with slotted rotors at rear because you wont use them. Me and Dwee looking into brake upgrade too, pads will be fine even with stock rotors. Just need something to help us brake later and stop earlier. Dont have to go all out on this area of mods (Depending on your application, if your street/track use and how hard/often you brake) as we dont have enough power to require such brutal stopping force. :P But my recommendation would definitely be change of pads, im also waiting for some aftermarket available pads. I was looking in the way of Ferodo. QFM sounds like the biz or Project MU or Bendix or Ferodo or if you can afford it... AP Racing? lol
