Brake discs - what mark to use?

[firehawk]

We were using plain standard Brembo discs on our AE82 endurance racecar and they work just fine. Drilled discs may have better cooling as they have more exposed surface area but as we have quite sizeable cooling pipes from the front bumper, there's been no problems with overheating.

Regarding the pads, we've had very positive experiences with Ferodo DS-series. The DS3000 has an amazing bite and doesn't lose it's character even when it gets extremely hot. The only problem with it was that it wore out completely in four hours of racing and we had to change new pads in the pits (not fun when the brakes are so hot that the paint on the calipers was burning). The DS2500 has similar characteristics but a slightly lower friction coefficent, which helps it to last a bit longer, enough to take us through the full six hours of racing.
