Well, I've had these brakes on the car for almost a year. Combined with the Michelin Sport 4S tires, I've only had the anti-lock kick in once, and that was when I tried VERY hard to get it to trigger.
Overall, these brakes work great. The only problem I'm having is that I can't stop the squeal from the Hawk 5.0 pads. Currently looking for a quieter ceramic pad. |

I'm sure you know, but just a reminder.

I just changed the front rims/tires to match the rears. In order to have a reasonable amount of space between the tire and the front spring I added a 10mm spacer. Since I was adding spacers, I put a 20mm spacer in the back. All four wheels now have studs.
This increased the space between the rim and the caliper a bit. It's still rather tight, but the extra 10mm moved the caliper to a flatter section of the rim. |

do we need coding for the rear m performance calipers if goin from the bosch gray ones with 330 rotors to the 345mm rotors?
im not seeing any pressure seal part on realoem for the m performance calipers. only dust shield if rebuilding used ones.is this just needed for other models than 335i F30 and m3 f80s? Last edited by jjjccc; 10-06-2022 at 01:09 AM.. |

I feel you need new pressure seals whenever you pull the piston out. Due to the use of metals with different expansion rates (Stainless piston and aluminum caliper), it's not possible to have a tight seal without the pressure seals. The seals are in there, regardless of what RealOEM says.

feelin rt u mean stop without pullin to one side? i had brembos on an acura once and man it would stop so quick u cud barely press the brakes or it would jerk u to a dead still stop best brakes i ever had. i dunno if the m performance brakes are meant to stop like that even with coding or maybe just the material pads u use.
i feel that way too! i got the bmw part number/ brembo repair kit listed on realoem from(i thought reputable company) in UK and it does say repair kit caliper.. no dust seals inside just the 2 boots for one caliper. i tried arguing with them and they insisted bmw sells this repair kit part number that simply does not work because no dust shields inside of them.i tried to explain that to them , that no pic is shown because theyre inside of them on schematics! i said i cannot use them to rebuild so its not a rebuild repair kit. they acted like it was normal that people just buy this kit get the boots and set them on a shelf to look at the boots with no dust shields inside. and thought that was their good argument. after they admitted it doesnt make since. brembo manual even came with them with bmw sticker on front. i cant find dust shields for these anywhere i can, but they want 40 buks per dust shield. stoptechs/centric wont be in stock anywhere until january!

Usually, the issue that indicates that coding is needed is a front/rear imbalance. It makes the car feel "squirrely". If there's a side-to-side imbalance (makes the car pull to one side consistently), there's a different problem and it might be able to mask a front/rear imbalance.

The abrupt grab that some pads have can be dangerous on the street because the car behind you is unlikely to be able to stop as fast. While the accident wouldn't be your fault, your car still goes to the shop. This is something I like to avoid.

Hello terryd5150,
Just stumbled upon this thread with the photos above. Im trying to figure out if the F80 380mm discs +calipers would fit in the style 658 wheels as i have the same. As you currently have the same wheels as I have but with the 370 discs would you say there is currently another 10mm between your caliper and barrel of the wheel? realise I would need a custom bracket to be able to install these but just doing a bit of research. thanks! |
