I suggest consulting with local Porsche racing experts who know your car and your tracks and have dealt with these issues before. I also recommend the Puhn book on braking if you are looking for ideas, particularly pertaining to ducting.

Ducting can make a huge difference. And probably all or nearly all combinations and permutations of body work and brake systems, and Porsche cars have known solutions. I almost went with water cooling on my previous car until I spoke with some pros (the guys and Kelly Moss) and designed a better airflow situation.

Ahhh, gotcha! Sorry I missed that thread ...not your fault

I think you will find that the Ate blue (or better fluid), good rotors in spec (i.e not thin from wear), and a good track pad (like the porter, pagid, PFC, or Hawks, et al) will be enough for DE. I assume you have a fairly stock car (of normal weight) and no serious HP mods like sc or turbo.

Is it fade you're getting? I can completely fathom how stock pads can fade under track duress, especially given certain tracks and/or high ambient temps. But I guess I am just having some difficulty understanding how good fluid+track pads+fresh rotors on a stock 911 can cook the brakes at a DE event. Maybe you're just that fast? In any event, I'd try Jack's suggestion as it is cheap, easy to do, and (from what I, too, have heard) effective. But honestly, I think you'll be fine as soon as you get some good track pads in there (be certain you choose a compound appropriate to your task, btw) as that seems to be the weak link given what you've described. You'd be surprised how much braking torque is applied by simply fitting a pad appropriate to the task. Oh, and FWIW, I couldn't stand the jurids on my 993 ...ugh!

Rim choice is often overlooked. Fuchs are not very good for brake temps. Somthing like 993 Cup's can make a differance.

+1 on track pads, track fluid, backing plate delete, and new rubber or SS brake lines. My 2750 lb Carrera dose not have any issue but I am not that hard on the brakes.

Honestly, I can't say I've had a problem. I've only had a little fade on two occasions. I'm looking ahead to next year when I do more events.

And, I'm a geek and like to do these kind of mods to my car. If nothing else, it gives me confidence. And I defend my position that having confidence is almost as important as having skill... until you cross the line into cockiness then it's a hazard

New pads are next. Then some type of cooling kit/deflector.
If I can outrun that.... I'll buy Steve's Super Stopper System.

Hi vet,

I think everyone here is a mod-geek of some kind ...kind of a prerequisite to membership.

If I may offer one bit of advice (from the BTDT file), use your mod money where you will get the best return ...your confidence will increase as a result of the more solid car you've just improved. So while I am not saying you will never need to upgrade brakes, from what you've said your brakes are more than perfectly adequate, and will be for some time. Address the pad/rotor/fluid basics and you're set for some time. I am sure there is lots of fun in the suspension and tire department that you could spend on. And don't ever neglect safety gear ...not "sexy" mods, but like insurance, something you hope you'll never use, but glad you have should you need to. Then there's "adding lightness" ...now that's a seriously great mod!! Best wishes on this very slippery slope ...oh, and post your updates with pics!

Well said.

I can solve your problem for under $20.00. I went to Wal-Mart and bought RV sewer hose. Ran is from the bottom of the a-arm and up the shock to the caliper. I tied it off with zip ties and they work just as well as the expensive mods.

Folks,

Brake cooling? Just follow the advice of Fangio Senior: "Less brakes - More gas...". Works every time! I can't believe everyone missed this. Are you ALL asleep??? Is it the holidays or what?
