Solutions for Cracking Rotors on Track?
I run OEM brake rotors and calipers with Raybestos ST-43 racing pads on road courses. I have had multiple problems with front rotors cracking, and am getting sick of losing track time because of it.
What is the solution? Brake ducting? Is that enough, or do I also need a big brake kit with better rotors? If so, which kit? Thanks.

I think it depends on driving style. I have never cracked a rotor and I just added ducting. I noticed at ACS it helped with fade later in the sessions. The flip side is a driver like Mike who can crack 2 sets in a day. Some say its all about the cool down after getting off track, but if its a cronic problem for you Richard maybe a BBK is the only way to stop this.
I remember reading about the Science of Speed rotors that have a better venting design. I haven't heard about anyone running them but maybe its worth a look before you jump into a BBK?

I don't believe ducting actually helps with rotor life. It does help with pad, front wheel bearing, and caliper life though. RacingBrake.com's upgraded discs last me a full track season (24 days) when I used to crack rotors every weekend. A front big brake kit is the ultimate answer though.

The only true fix is a BBK. The initial cost turns off a lot of people, especially since ~2000 can purchase close to 40 rotors, or a whole lot of pad, or a combination of. However, looking strictly from a ROI and time point of view, I believe a BBK is ultimately worth it.
~2000+ initial investment
- double pad life (roughly) at marginally higher cost
- Rotors should last a year, possibly more
- Saved time due to not changing rotors
- Saved time due to being able to swap pads faster (not that stock takes very long at all)
- ability to recoup the majority of the initial investments upon selling the BBK. (~1500+)
I believe ducting will still help with pad life, although to a smaller degree. Wheel bearing life would be extended as well.
Richard, if you're serious about a BBK, I've been trying to get a group buy together that will realistically happen close to the end of the year with enough interest and commitment.
