The piston has full contact with the pad. The piston face is chamfered, for one, so it kind of appears to be off the pad. Also, the angle we can take photos from exaggerates the illusion. If you take the pad off there's a perfect circle from the piston on the back.

First time at the track with this setup with EBC yellow pads, and I was happy with the performance. Thought I honestly wasnt abusing the brakes since it was the first time out. We'll see how it goes in the future, but so far so good.

Looking for advice on reasonable brake upgrades for my 128i. Ran 3 DE events at Watkins Glen last year, looking to do 4-5 this year. Ran stock rotors with Hawk HPS and Motul 600 fluid, bled a week or so before the event. Was mostly good aside from two things:
1) Brakes started fading pretty badly after I moved up run groups and was getting faster. Not something I want going downhill into a turn. 2) Rear pads were annihilated somehow. My guess is the e-diff ate them up Day 1 which was rainy, did not get into TC at all, only a few moments of ABS. I've ordered stainless steel lines, but additionally I've been eyeing 335i brakes or F30 brakes as options, but these will require new wheels, as I'm on 17" 262s, so that kind of blows the budget up. Also been looking at the BMW Performance brakes with the piston retrofit, since these will fit my wheels, but wasn't sure if this would be worthwhile, or a half-measure. (Been looking into sourcing 135i fronts and 328i rears to assemble the kit on my own w/o the PY paint) Lastly, had considered the BMW Performance front bumper and retrofitting the 135i cooling ducts and fender liners, but I'm not sure that the performance/$$ ratio makes this worthwhile. I'm not crazy about the look of the Performance bumper, and getting paint matched is always a little dicey. Given that I'm doing 4-5 events/year (8-10 days), is it even worth doing this, or just go to a dedicated set of rotors and track pads and leave the rotors/calipers stock size? Any advice would be appreciated! Last edited by crowtrobot; 01-24-2017 at 08:46 AM.. |

Ya, HPS are not even an aggressive street pad. I use them on my winter car so I can swap to DTC60 when at the track. All Hawk compounds are compatible with each other, so if you stay with Hawk pads, no need to swap rotors when you go to the track.
The ediff will do a number on the rear brakes. Even on dry pavement I was overheating my rear rotors. A real limited slip would help. |

Watkins Glen is a pretty fast track, and can be pretty tough on brakes.
Personally, I would prefer a more track oriented pad, a high temp fluid (which you have), and improved cooling. |

BlackLizard Re: cooling - is there an option besides going to a different bumper/135 air ducting? I'd rather not be cutting up parts to run my own ducting if I can avoid it. Bumper kit unpainted is $1200 + freight on Tischer, plus liners plus ducts - seems like a lot of expense to me for gains that aren't immediately clear performance-wise (some cool air vs. no cool air is quite clear, haha). My hope with the bigger brakes/dedicated pads is more bite, less time on the brakes, and more heat sinking with the larger rotor, so hopefully the integrated heatload inside the wheel well isn't so bad. Not arguing mind you, just my thoughts. Appreciate the feedback, thanks! Do you visit Watkins often? I'll be there in April for the local BMWCCA chapter's DE.

No worries.
I came across a thread over on e90 post for the installation of NACA ducts on the under tray that I thought was brilliant. If you DIY the installation, you can do it for under $100 and if you still want to go to a BBK afterwards, you can. Here's the link to the thread http://www.e90post.com/forums/showthread.php?t=1287364 It was my first time at The Glen, a buddy of mine owns Apex Driving Events and I help him out. |

Bend the heat shield on the rotor back as far as possible! Use it to scoop air. This is less effective once you move to wider wheels, but it is still drastically better than the heat shield blocking airflow to the rotor altogether.

Finally got a chance to run the car hard for two days at the track at Oregon Raceway Park. The combo of these slightly larger rotors / stock calipers/ hi-temp fluid, and EBC Yellow pads was a great combination. Braking was great, with only mild fade at the end of the later sessions. I suspect I'll go through these pads pretty quickly, but they should last another 2-3 track days. Overall very pleased with the track performance of the 128 braking system.

So there’s two potential aluminum calipers:
34116769091 328i 34116769093 Z4 What is the difference between the two? I’m looking to fit as big of brakes as I can inside the style 262 wheels. Possible options are: z4/328i aluminum calipers + 330mm rotors z4/328i aluminum calipers + 312mm rotors 328i steel calipers + 330mm rotors I don’t see why the aluminum calipers and 330mm rotors wouldn’t clear the 262 wheels considering the 135i calipers + 338mm rotors clear it. Can anyone chime in on any of the possible options?

Sorry to bring back this old thread, but i have a couple of questions.
Basically if i understood correctly, one can keep the 125i calipers (front and rear), get the 330i/Z4 carrier and install the 325mmx25mm discs? The two piece Z4 ones should be the ones to go for, since they are two piece meaning lighter correct? What about the rears? do the 330i/Z4 discs also require carriers for the calipers to mount up? Isn't this the same setup some teams were using when racing 1 series cars? This would be an ideal setup for me, since everything is original BMW and i do not need to have to go to the TÜV and have registered the modifications, sadly this means i am stuck with EBC pads only for the REC90/RC90 label (European label for being street legal) and i can run redstuff or maybe yellow stuff on street and track. |
