Cajundaddy wrote:Ok vetran track guys we need your input. This weekend my brother and I completed a two day time trial at Buttonwillow in unusually cool conditions and both our front rotors are really warped when hot. My car has Balo's and his are OEM but they are equally thrashed. I doubt they could be turned out because the serious judder only happens after lap 2 (hot). It gets so bad that in heavy braking zones I can barely hang on to the car. Any good solutions for better pads/rotors or better heat management for the fronts? GT3 ducts? Dryer ducting? Evaporative mist system? We are running Boxster BSX cars that are just class legal weight (2950) with pagid yellow pads and SRF fluid. No noticable fade issues but really rough rotor judder under heavy braking as the session progresses. Ideas?
Hey Dave
We had a great time running you you guys this weekend in your "cheater" BSX cars... (Inside joke)
We had similar problems with Gregs 911SC and tried every combo I could come up with.
The brakes worked great just warped and cracked rotors and we have huge brake coolers
For you; GT3 lower A-Arm scoops is a start but the key is brake pads.
We settled on Raybestos ST-43 and we are very happing with the braking and pad/rotor life.
Brake similar to Pagid orange. (better on some points worse on others) but pad and rotor life is increadible.
This is after 2 time trials with two drivers and one of them being a moderately "aggressive" braker... (Not naming names...)
They look like thay have maybe 10-20% wear.
I think they stop so well we are just not having to use the brakes as long and therefore not putting heat into the rotors.
Give them a try. Bill Ibbeston turned me on to these after he used them for quite a while.
