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.

 

ducting with the oem setup is generally the cheaper way to go. bbk also takes care of the problem and you don't need to add ducting.

 

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.

 

So are you all saying if I'm willing to shell out for a BBK, I don't need to bother with ducting?

 

what discs are those?
i'm getting lost at their web site....

I think the PF 2pc upgrade would be the best option for a NA car. 1/3 the price of a BBK.

 

Is it even out yet? I just remember Billy 'leaking' the info and then it died...

 

Haven't ordered myself:
