FBS ("Brake Fading Compensation")
BB_RAB ("Brake Standby")

Also, changed the stock pistons to stainless ones.




Thanks for the write-up and pics.

Question about the BMW performance callipers - are they the same as the stock 6 piston 135i callipers except for the color? Information on other threads is confusing.

Yes they are.

Nice choice for your exhaust. I took the same approach for the same reasons. However, you may want to consider removing the stock resonator as that goes from the two 2.25 pipes to one 2.5 pipe, so you still have a major bottleneck possibly preventing you from taking advantage of the larger axel back piping.

When I did mine, the resonator was replaced with a two 2.25ish inch to 3.5 y pipe.

I'd recommend a diff brace as it's cheap and easy to install. I got the precision works brace as it looks stiffer than the flat BMS brace.

Thanks! I'll do that later on when I build the mid section

Thanks for the recommendation, but I don't se the point of it to be honest. For a strip car, yes but for a track car no.

Alindquist - did you solve your brake pedal issues? I ask because I have a similar problem and wanted to compare notes.

I have a 128i with the BMW performance calipers, SS brake lines and motul fluid. I already coded off those parameters you mentioned a few posts ago - and while it did improve the consistency of the pedal it's still kind of soft. I already bled the brakes several times and even activated the DSC pump through the computer as well. But my brake pedal still doesn't feel as firm as I want it too. Its also not temperature related because I have cooling ducts and when bleeding brake fluid it's not cooked nor does it have air in there.

I noticed the 1M has a different brake master cylinder than the 128 and 135 and I'm wondering if that's what I need to do. Any input welcome.

The 1M/M3 brake master cylinder should not be necessary for the performance/135 calipers. Have you bedded your pads/rotors properly?

Yea, I have. I have been dealing with this for the last couple of years and both years I've done the bedding procedure and can see a nice layer of pad material on the rotor. Besides, if they weren't bedded I would have less braking performance but it wouldn't feel soft so I don't think that's it.

Wondering if at my miles (around 100k) the seals inside the master cylinder aren't as good anymore.

Definitely not true. Non bedded pads/rotors can definitely affect pedal feel. If the ridges aren't "in sync" then there will be some mushiness as the pad first contacts the rotor.

I see what you mean. But no, pads and rotors were bedded.

Any more photos of your intake setup? Details on how you made the plastic flow tube?
Thanks
