I did 3 runs at the autox today, and at the end of the third run i had really bad brake fade. Almost like they werent working at all. Anyways, can anyone recommend some good ss lines, and some brake fluid? (Not from corksport) Thanks!

Rather than spend money on SS brake lines, just flush the brake system with new fluid. For autocross use which fluid you use is less important than maintaining the brake system by flushing it periodically. I've just been using Castrol GT/LMA which is nothing special but works fine.
Before replacing the brake lines, I'd also consider new pads. Something like the Hawk HP+ works well for autocross but is dusty.
How long has it been since you've flushed out the system?

I havent flushed out the system since Ive owned the car (almost a year). Someone just recommended Dot 4 fluid instead of Dot 3. Is there a big difference there? I just put KVR carbon fiber Pads on all 4 corners, are the Hawk's better? Kvr's are pretty dusty to. Thanks for the advice!Eat ****.

Dot 4 has higher standards, but i don't think you'll ever be able to tell the difference...as long as it's well maintained, 3 or 4 will be fine.
If you've just put new pads on, then i gather they may have gotten glazed...or thier not very good pads...i dunno, don't know about the KVR pads.
As for the Hawk HP+ recommendation...I have the HPS pads, and was told by a few verteran autoxers, that the HPS would be better suited to a street driven car. Where as the HP+ are racing pads and require more heat to work optimum and may chew at the rotors more. Cold in traffic or around town braking may be hindered. And yes, the Hawk pads are dusty as hell, be prepared for many a wheel cleaning.
Actually, on Saturday we had a Prosolo style full day practice, and i was doing 4 back to back runs (x2 40sec courses) in a toal of about 8 minutes. Brakers where just fine.
(ProSolo has two mirrored courses side by side, there is a drag style start with a light tree and everything. You both run at the same time, then crossover to the other course, then back again. total of 4 runs, 2 each side. It's a total BLAST! it's fast, intense and really competetive. Your now head to head with another car, not just the course or the clock. It's very different from Solo2 in that respect)

Once again, though, start with flushing the system before bothering with other stuff.

Valvoline synthetic DOT4 is readily available at most automotive shops and is dirt cheap. That's what I use."Never run out of real estate, traction & ideas at the same time"

Cool thanks alot. I bought the KVR pads from corksport, and they told me they were one of the best pads they sold. WHo knows, Ill prolly try the HPS pads when I get paid next. Tirerack.com you said?? Also, I just put on new rotors in the front as well, would that have anything to do with it?? Ill be flushing out my system tomorrow....thanks alot again.Eat ****.

"feel" is important...
i drove Jason's H-stock car with aftermarket brake pads and they're on the level of the best braking feel ive ever driven.
the reason you had brake fade is fluid, but that doesn't mean you can't upgrade other parts."Never run out of real estate, traction & ideas at the same time"

That the aftermarket pads provide higher stopping power for a given amount of pedal travel means that I can spend fractionally shorter time on the brakes too... but that's grasping at straws, really.
An added bonus of the HP+ pads is that they are much less prone to not working when I'm driving on the highway when it's raining- the factory pads were horrible for that.

I agree on pads before SS lines too, but SS lines *are* a nice addition, at least to me. I wouldn't put it on the bottom priority.2006 Mazda 3 hatchback manual
