question about drilled/slotted rotors

[-RJ-]

does it really make much difference that stock ones? i just want to get some info because im getting new rotors

eh... for daily driving, not really. they mostly look cool.

the purpose is to help dissipate the heat and gasses created under repeated, heavy braking. the gasses build up between your pads and rotor which reduces the coefficient of friction and hinder their efficiency.

if you want better braking for a daily driver, upgrade your pads and fluid first.

Dex is right on.. drilled and slotted help with the heat a bit.. but I doubt it would make a noticeable difference on anything but a track/race car.

I'd buy them for the looks if that can justify the extra cost.

You're better off doing the Q45 front brake upgrade and just using blank rotors.

Slotted rotors are supposed to keep a fresh face of pad material. Under extreme braking, the materials of the pads will heat up and glaze over reducing braking efficiency. The reason why race cars have the slots and drills is because they use pads designed for the high operating temps that they work on and frequently meet and exceed the temp at which glazing occurs. Street and even mild race pads are designed for optimal braking when they are cold because your brakes seldom heat to the extent of glazing. All in all it's pointless for street braking.

thanks for the info guys. i was just gonna replace my rotors, but i guess ill get it anyways. it does look cool

ive got em all around, i feeel a difference in extreme situations where im on the brakes alot +1plus they look sweet

Do you have slotted, drilled or both?

[S3t0_S13]

both
