Tell me the scoop guys. I would like to know the best brakes for track purposes. My 996 Porsche rotors are cracking all over the place on my Z06. I will probably get CCW wheels to fit bigger rotors/calipers.
I don't want to mess up any computers, but I do want to stop the best over and over at the tracks. What are my options?
Also, does anyone have a good track Z06 (02 or later) on this forum with all the right stuff????? I would like to PM them. Thanks.
Could you post pictures of your StopForce rotors; I'm considering them as an upgrade and would like to see what yours look like after heavy use. Thanks.
If these don't work out, I will get Brembo's Big Brakes all around...
BTW - I've owned several late-model Porsche's which I've tracked quite a bit and it is normal for Porsche rotors to show small cracks from each hole after heavy use. They need to be replaced only if the cracks extend between the holes; I've never had mine do that so I've replaced them only when they reach their minimum thickness.
Best bang for the buck except if you plan to race for thousands of $s would probably be stock rotors, race pads, race fluid, and DRM cooling ducts with Phoenix (or LG) spindle duct holders. That's what most people run, including the T1 racers, and they are very competitive (actually they lead the pack almost always as far as I know).
No need to get crazy and buy big brakes and then have to spend thousands more on bigger wheels and tires, etc.

This topic has been reviewed several times, and there are several opinions on what to do. I'll share mine since I have tracked my car once or twice....
For stock brakes, what Brian said is true, and that is what I run. But, there is some required maintenanace associated with the stock calipers-meaning even with brake ducts, the seals in the calipers melt, and need to be replaced. The lifespan of the rotors is marginal with more aggressive pads-and that varies between cheap repros and others.
If cost really is no concern, then look at the 14" Brembo kit, Stoptech, or Alcon (Baer) that gives you a much bigger diameter and thicker rotor. Doug Rippie also has a AP Racing six piston front, four piston rear set up. The initial buy in is much higher. I would talk to some of the guys that have big calipers and see what they tell you about rotor life, consistent braking, etc. IMHO
If money is no object and you want the ultimat then a Big Brake Kit such as AP, Alcon, or Brembo is in order.
A step down and slightly cheaper would be either the Wilwood or StopTech Big Brake kits.
If money is an object the OEM brakes can be upgraded quite nicely.
The weakest link in the system are the OEM rotors which are prone to heat checking, cracking and warping and poor endurance. They have poor metallurgy being made in Brazil. There are 2 options in dealing with them and that is to buy cheap rotors and replace often...almost considering them as routine disposables.
Or, I prefer rather to have them Crogenically treated which extends the longevity 3X. Slotting is also an option and increases performance. DO NOT used drilled rotors (except the Brembo's).
Here are my recommendations:
- Cryo'd rotors
- Slotted rotor's (optional)
- Race Pads, either KFP, PFC '01's or others
- DR SS Caliper Pistons (option are rebuilt VB&P F1 Titanium vented tipped caliper pistons)
- Goodridge SS Lines with -AN 3 connectors (DO NOT use the Banjo connectors)
- Race Fluid either Motul 600, AP600, Wilwood EXP or new GS610
(make sure the ABS is flushed initially using a Tech II Analyser)
- Speedbleeders
- DR brake duct extension
- LG Motorsports hub duct (optional Phoenix hub dust)
- Optional Seine Systems MPC
- Pegasus or Mallett Brake Bleed Catch Bottle
- Aeroflex Silver High Temp Duct Hose
Finally, be sure and consult the Racing Brake Primer in the above post in the Racing Forum

Yup, good stuff. For those reading, PFYC carries the following items, almost all of which are either in stock now or will be soon:
PFC pads
Carbotech pads
Powerslot rotors
DRM Stainless Pistons
New GM Caliper Seal Kit (for use with SS pistons)
Goodridge Stainless Lines
ATE Super Blue or Typ 200 fluid
Motul 600 Fluid
DRM Brake Duct Kit with extensions
Phoenix Spindle Duct Holders
Motive Brake Bleeder
Coming soon: Wilwood brake kits for those who need more
Thanks guys. I have my research cut out for me. I see the stock rotors used as disposables okay, but that's just one more thing I have to keep up with while at the track. Keeping up with a great brake package is necessary, but you know what I mean.
I can't afford the 18" wheel upgrade at this time either, so it looks like the few posts have really given me some good places to start! Thanks. Perhaps some good service vendors to choose would be my next question. PFYC I think responded personally in the above posts!
PFYC is always here to help. It helps that we have personal experience with a coupe and then Z06 on track. I myself am a high performance driving instructor with almost all of the clubs that I go to track events with. I'm not a racer, but I know a lot and will always do my best to help you.
