I would like some input from anyone with knowledge or experience in the following area.
If the front brake rotors (and front only) are replaced with a drilled rotor will this unbalace the braking of the car.
Specifically an enthusiast model with non Brembo brakes.
The intent is to imporve the front brake performance by reducing the heat build up in the rotor. From the information I have found it apears the fronts run 100+ deegrees hotter than the rears. I expect reducing the temp would imporve the performance.

 

cross-drilled rotors do nothing to reduce heat buildup in the rotor, and they have no impact at all on the balance of the brake system...

To improve your brake performance, you need better brake pads, some that will work at higher temps and not fade when they got too hot. Carbotech Bobcat, Carbotech Panther, Hawk HPS, Porterfield R4-S, Padig Blue....

If you really must have cooler running front brakes, then you need a larger heat sink... the rotor takes forward kinetic energy into heat and then dissipates that heat, basically a heat sink... to do that more efficiently, you need a larger, more massive rotor. Something like a Stoptech 13" front kit will do the trick.... or for more "bling" the 14" kit....

Thanks for the response and the information.
