What mods to improve stopping distance?
I am contemplating buying some AP Racing 6pot/4 pot BBK to replace my stock Brembos. After doing more reading, the general consensus is that BB kits do not improve stopping distance. Rather they just provide extra protection against brake fade. So my questions are:
1. If I'm only doing 20-25 minute track sessions, would a BBK provide any real world benefits. And by real world I mean improvement in lap times.
2. Is there anything I can do to actually decrease stopping distance besides decreasing the weight of the car?
Thanks.

maybe try the stoptech upgrade for your stock brembos

-pads <get the right compound, swap them out when you go to the track
-tires <stickier and wider
-driving instructions
-proper alignment <this will affect your max grip alot, so you might need suspension peices to get it dialed in if you are lowered.

well yeah but it reduces heat, cleans the pads and the lines help prevent the that spongy feeling you get when your stock lines expand.
i know a BBK and certain pads change the initial bite and distance but all working together this creates better brake perfromance overall. i know the original posters question was distance but i think if he is doing 20-25 min sessions he might need to look into those things in addition to just bigger brakes. i remember i went tracking my Z with the non brembos and i had different issues with brakes every event. changing rotors, adding the right pads, fluid and installing lines really helped me out.
At the moment I'm running stock Brembo calipers, braided lines, slotted Brembo rotors, AP Racing Brake fluid, Endless brake pads and 285/295 R compounds. BTW I have a built/APS TT.
What else can be done? I don't mind spending the money for a BBK if it provides a noticeable improvement in braking. I know it'll provide more consistent braking due to decrease chance of fading but I would like an increase in performance from the 1st lap.
Would a change in the master brake cylinder improve things?
Allignment I'm still playing with and I could always do with more instruction. But just isolating it to the car's braking system - what can be done?

Thanks for all the suggestions.
So the only thing a BBK does is prevent fade? I think I'll probably spend the AUS$10k on someting else then.
Can guys with BBK who track their car chime in - was it worth it?

Thanks.
1.Install a drag chute
2.Only drive up hill
3.Drive very slowly
You are welcome
If you did anything that would increase the clamping force on the rotors it could severly mess with your abs system. IE changing your brake master cylinder. After all you can lock up your brakes as they are.
If hitting the brake pedal can still lock the tires (or activate ABS), and you want shorter stopping distances, you need to increase grip. Stickier tires, alternate alignment (reducing negative camber likely making handling worse), better damping, or increased downforce are the likely candidates. Realistically, increased downforce (perhaps the new splitter being advertised here?) stickier tires, and less weight are probably the best choices. Better suspension will probably help to some degree, but I would surmise only minimally unless your braking zones are especially bumpy.

A BBK is 110% worth it on the track. If you have never experience brake fade on the track, it is not fun. A BBK, however overkill it might be for your application now, is worth it because no matter how much you mod your car, you will still be able to stop at the end of the straight. What are your plans for the car as a whole? Going F/I or staying N/A? How deep into suspension modding?

- built TT (APS)
- Suspension: at the moment Koni with Whiteline springs but when I finish my car (waiting for seat and roll bar), will be getting Bilstein to organise my set up.
You have the AP right? How has it been?
If you want to learn about braking, more than you wanted to know, start with this page, especially the Physics of Braking Systems paper:
http://www.stoptech.com/tech_info/te...e_papers.shtml
It's complete with equations that you saw in your high school physics class and never thought you'd use! But it's written so you can understand even if mathematical formulas scare you.
