Haha, always the salesman. I've got a set of S-20's on the way. I didn't hear back about that BBK though. Shoot me an e-mail.

Guys, just so you know, every OEM BMW Brake caliper has a piston/pistons ONLY on the INSIDE of the rotor. I may be wrong, but if I am, it's only on new M cars, or very old cars.

They use what is called a "floating" caliper setup. The single or dual piston (on X5's, only, if I recall correctly) only pushes on ONE side of the rotor. The caliper is on a pair of slides, and as pressure is applied to the inside of the rotor, the outside pad is pulled in towards the rotor, thereby applying the brakes.

In my opinion (and Brembo's, and Wilwood's, and Rotora's, and Stoptech's, etc etc) it's better to have a piston of EACH side of the rotor, but hey. Those crazy Bavarians over in Munich haven't led me wrong yet. My brakes work well enough.

However:

I'm a VERY aggressive driver, and I make it a point to hit my plethora of local awesome canyons every weekend, and sometimes in the week. My brakes get BEAT up. Our brakes do experience some intense fade. I'm not feeling all that safe on my brakes lately, in the canyon's. I'm probably going to pony up for a front BBK.

Now is the time - we're selling one kit at a ridiculously low price.

1 word of caution, anyone considering aftermarket brakes would do well to read about Car and Driver's experience with doing so on their endurance race prepped 335d. March 07, pg 84.

Also, a significant amount of brake fade is due to the rubber brake lines expanding with heat. Try SS brake lines.

Ps I'm not against the idea of BBK. I just want to find the answers.

Back in my day, BMW 3 Series cars didn't come with forced induction. We had to make them forced induction ourselves! You kids these days with your 335's... you've got it good![/GRAMPA STORY]

That's wonderful advise. Thank you! I'm going to upgrade to ss lines before I drop the bomb on a BBK.

No, I was thinking that you purchased them from Josh at Status Racing. I know Josh (use to be from ACHTuning).

Gotcha

///Matt - You know that Brembo's come with SS lines, right? If you're eventually going to do a BBK, then why spend that money twice?

eninetytwo - DPE R20's - We sell them, so tell us if you need a set.

S4 - No sir
