Need new brakes - Page 3

well the theory behind that would be larger surface area for braking, more area to make contact with pad and caliper, would not get as hot either. I think.

Actually Brembo drills them because that's what people want (for asthetics). All their BBK's are available slotted. Brembo actually stated publicly that they spec x-drilled on Porsches, Lambo's, etc because people like the way it looks, not for functional reasons.

All this talk about brakes, and no one has mentioned tires. Tires are what stop the car, brakes just stop the wheels.... Having a $10,000 Brembo brake set is useless for example if you have Kumho 712's. Sure your brakes will never fade, but they'll never be pushed to their limit either.

In my books a BBK is pretty much a waste on a street driven car. The only advantage on the street is pimp factor and a nicer pedal feel, but there is almost no performance increase. The downside is mega increase in pad/rotor replacement cost and a big increase in unsprung weight. You can lock up street tires with the OEM setup and track rubber with racing brake pads. So like thinair said, you need better tires if you want to stop faster.

On a track the big rotors act as a heat sink and reduce average rotor temps. This makes the pads last longer and usually eliminates fade and overheating.

It's not possible as far as I know. You need to upgrade both the caliper and rotors at the same time.

If you don't track your car I would not bother unless you really want to do it for looks. For example if you have 20" wheels stock rotors can look pretty wimpy.

You can add brake ducts if you are having overheating problems at the track and don't want to go for a BBK. It made a huge difference for me.
