Have you compared BBK to stock calipers with track pads, SS lines, and racing fluid? It's my track experience that those 3 things added to stock calipers make a big difference on the track. The argument was made that my Pro racing experience is on GSXR's, not in cars, so I am looking for other opinions. Which of course ignores my car track and auto-X experience.... Thanks. Ps Also correct me if I'm wrong, but doesn't the 335i come with 348mm front brakes and cooling ducts, stock? |

Yes i THINK so ... but isnt it only a one piston?? Ive heard that but im not sure how that would function correctly when there is no piston on the other side of the rotor to push back and even out the force.

many people do autoX in the states, as its not that expensive to get into it as opposed to track days. autoX might just put more stress on the powertrain/brakes than a day on the track (roadcourse)
And I wont post who is selling brembo kits for $2700, but it is out there and not hard to find. |

Stocks will be 2 piston (1 each side).
Its quite easy to test stock brakes, acc. to about 130-140 mph brake as hard as you can to a stop (where safe to do so), acc. away and try them again. Nothing there ? Thought so |

1 each side? what do you mean? a 2pot caliper means there are two pistons on EACH side pushing the pads in. And what about your test? A civic can do a small number of 130mph-0 tests without fade or failure.

2 pistons each side = 4pot

S4iscool, I meant one piston each side of the disc. What did you think I meant ? As for a civic, who cares ! I don`t drive a civic, so don`t really care if its stock brakes that are better than PCCB`s. The stock E90 brakes aren`t upto serious use, they`re fine for regular driving but really start pushing it on winding country roads and you soon start to notice it. |

I dont know what size brakes come on the 325D, but the 330 has 330mm fronts and the 335 has even larger ones. The 330 stock brakes can handle a number of highspeed scrubs without fading and I would think they are more than capable for most st drivers. Are you saying your brakes fade after 1 hard brake? Then id agree that your stock brakes are crappy.

I'm sure that this is a really stupid question, but can you get a BBK for the front and use the ample OEM 335c brakes on the rear? I'm guessing no, but that would be ideal for me. I could rationalize a front kit, but all 4 is just too much and being able to utilize the big front setup on the rear would tip me toward this upgrade.

AutoX you run the car for what, a minute or two tops? It is stressful but not terrible. A road track you are beating the crap out for the car for multiple laps at a time, much harder on the car, especially temp wise with the 335i if the panic threads are to be believed.

Upgrading the brakes is as beneficial to your lap times as upgrading the cars power. Brakes that grab harder and have less fade allow you to brake later and that translates into a faster lap time. And, FYI. I bought rims to show off the car and I might buy brakes to show off the red Brembo logos, but who cares? You certainly shouldn't. I can't find enough time out of my day to care about what everyone else is doing.

you don't have to have a 4 wheel kit to have no brake bias. stoptech front brake kits for the E46 330 are balanced and designed for the OE rear brakes. Now, on the other hand, if you buy a great big brembo front kit and dont get the rears that were designed to go with it your car is going to dive like it is its job.

I'm not a brake expert, but I would think that your front brakes would start to fade before the rears since they are doing more of the braking. I also never stated that more braking power was needed, and I don't think that BBK's give any real advantage over stock in that department anyway. They prevent brake fade much better than stock and they look cool, aside from that they make your wallet lighter. Are they necessary for most people?... nope, not unless you track your car seriously. I don't think a BBK messes up your braking though, I would like to see something prove me wrong though.
