Do you mean the yellow/gold colored Brembo's that come with the Performance Brake Kit vs the standard 135i brakes. IF so they are the same except for the color/writing.

This is actually a good question. I believe he is talking about the aftermarket Brembo BBk vs. our stock Brembo made 6 pots. Off the top of my head I would say the internal piston is probably a different material, shims are different, all the lines etc. but I don't know any of that forsure.

6 pistons doesn't mean the same thing. Our 6 piston is technically crap. The M3 / 1M brakes are better and they aren't 6 piston. If you get the true BBK 6 Piston from Brembo it will be a huge difference.

I just don't understand what's so crap about them?

Unlikely. If you were racing every weekend and knew that your brakes were a weak link, yes it'd be worth it. But since you're asking to begin with, and not providing any info about why your current brakes are a problem for you, then the answer is most likely no.

The stock brakes will stop as well as any aftermarket BBK for ONE stop. Repeated stops from high speeds the stock ones will deteriorate quicker, but still, they do the job. If your asking this question you undoubtedly don't need to upgrade.

I'm still not sure what you're asking. If you mean the Brembo BMW Performance Brake Kit that costs about $2100 for a front kit, that's for 128i and is the same thing that comes stock on 135i.

If you mean the Brembo GT that costs about $3700 for a front kit, the advantage is it can stand more heat on track. It has no advantage for street.

The biggest difference between the 135i M-Sport 6 piston brakes and a BBK is the rotor. Our stock rotors are thin and can't handle as much heat, so the heat is transferred to the calipers (pistons and fluid).

As the others have said: if you're tracking the car A LOT you will want to invest in a BBK. If you're doing mainly street driving or autoX, you're better off spending your money elsewhere.

Best bang for the buck brake upgrade IMHO: SS lines, DOT4 fluid, Cool Carbon pads and titanium shims.

Titanium shims are only needed if you're tracking. For the short AutoX runs you don't need them.

The difference is more torque (larger diameter) and better cooling (rotor is 7mm thicker and vented two-piece).

Only reason I went with the GT kit was I like to take my car to the track and didn't want to risk brake fade or cracking pistons. Plus it fills out my 18" wheels nicely

On the street pads alone would make a much bigger difference then the GT alone.

They are better rotors, but complete over kill for the street.

thank you was asking the same thing... the slotted and drilled rotors can be used on the newer grey calipers I am assuming correct?

Yes, the Perfomance rotors can be used on the standard (grey caliper) 135i brakes. I have them on my car!

awesome thank you for the quick response now how about for the rear? and also what is the cost do you remember off hand?

I have my car going in for its first scheduled service and was thinking about getting these put on...

I think I have some rotor warp from maybe hitting a puddle while the rotors were hot or something. I am getting a small vibration in the pedal on braking...

thanks again for the info!
