AP racing kit for street use?
How is it for street use, I currently have the 2NH but am looking for something smaller so I could fit the wheels of my choice. The brembo is too big but the AP might just work.
Thanks! |

I have the Ferodo DSUNO's on my front kit. Surprisingly don't make much more noise than OEM pads..
So far so good as a street setup

I found that the Ferodo track pads don’t make much noise once putting them on, but a decent bit once using them on track. Lots of variables, tho.

You could also always go with the standard blue brakes from BMW. If you're not planning on tracking your car, this is probably much more affordable than AP Racing.

Also considered that, do we have part numbers on those? Wanted to see how much the total would be.

Rears: https://www.realoem.com/bmw/enUS/sho...diagId=34_2201 Best bet is to shop around the forum a bit. Those brakes were used on a number of M cars (M2/M3/M4) for a number of years. M2 - 2016-2018 M2C - 2019-current (optional/standard in some markets) M3 - 2012-2018 M4 - 2013-2019 I'm willing to bet you wont have any trouble finding someone who pulled a set off one of the above cars to upgrade to more track focused brakes. |

how much weight would you save by going from m2c silver calipers and rotors to ap setup? I assume ap setup would be even lighter than the m2 blue brakes so the weight difference between silver m2c and ap would be substantial?

If you browse through our Essex blog, you'll see tons of owner feedback on the suitability of our systems for both road and track. Here are a couple examples of customer feedback after 4-5 years and 50,000 miles of combined road/track use:
https://www.essexparts.com/news-blog...cing-brake-kit https://www.essexparts.com/news-blog...cing-brake-kit Quote:
Front brake caliper weight: Blue M2= 8 lbs. Silver M2C= 10.7 lbs. AP Racing CP9660= 6.2 lbs. (+0.5 lbs.for CP9668) Front brake disc weight Blue M2 380x30mm= 24.2 lbs. Silver M2C 400x36mm= 30.2 lbs. AP Racing 372x34mm= 21.4 lbs. To get the total off the nose of the car, you'd double the numbers above (I don't have the pad weights handy, but they factor into the total weight savings as well). On the front, our Competition Kits shave in the ballpark of 25 lbs. of unsprung weight vs. the big M2C setup, and about 10 lbs. vs. the OEM blue/base setup Rear brake caliper weight: Blue M2= 6.2 lbs. Silver M2C= 8.0 lbs. AP Racing CP9449= 4.95 lbs. Rear brake disc weight Blue M2 370x24mm= 20 lbs. Silver M2C 380x28mm= 21.2 lbs. AP Racing 365x30mm= 16.8 lbs. On the rear our AP Racing Competition Kit saves about 12 unsprung lbs. vs. the larger M2C setup, and about 10 lbs. vs. the standard blue rear brakes. Total unsprung weight savings with our Competition Kits at all four corners are close to 40 lbs. vs. the larger M2C system and 20 unsprung lbs. vs. the standard blue brakes. Our kits will fit many lightweight 18" wheel/tire packages. When you factor those savings in, you may be looking at 60 or more lbs. of unsprung weight savings. Huge bonus...you don't have to remove our entire caliper to remove pads like you do on the OEM M2C calipers. You can see the M2 discs above on a scale in this Essex Blog post. Here are our AP Racing Pro5000R calipers next to the standard blue brakes...which in this case were turning green after only a couple visits to the track. Spaceship vs. biplane. |

If one isn't quite as concerned about pure weight savings and fitting inside 18" wheels, our AP Racing by Essex Radi-CAL Road Kits for the M2 are also an option. These have painted calipers and dust boots for all weather durability. Our front Radi-CAL Road Kit is 10 lbs. lighter than the OEM M2C front brakes, while the rears shave a couple pounds. They run on 380mm discs front and rear, so wheel fitment will be a bit tighter than our Competition Kits.

Also I have been told that even 19inch TE37 won't fit in the OEM front 2NH calipers. The street version of AP front caliper seem to be able to fit any 19 inch, am I right? If I decide to go with 19 inch, do I have to change the rear as well? Last edited by Xerok; 02-04-2021 at 11:15 PM.. |

wavyyyy Don't go OEM Blue brakes, if you ever decide to go 18" e88's the calipers won't have enough clearance for the barrel. AP all day. I've ran them daily on my e92 M3 and now my M2C, no regrets.
The AP Essex kit in 9660/9451 is the best setup AND best fitment friendly for 18" wheels in general. If you are a heavy track user, perhaps 9668 is a better bet but keep in mind that a thicker pad is used but still very fitment friendly. Xerok A fellow member just bought the front 9660 kit and ran 18" TE37 with his stock comp rear kit. There's a thread somewhere about it. |

Q: Is it okay to just buy your front-only brake kit?What about the rears? A: Our front brake kits are designed to very closely mimic the OEM torque output on the front axle.That is accomplished by carefully sizing the discs and caliper pistons.For example, if we increase the disc diameter in our kit vs. stock, we decrease the overall piston area to produce the same overall torque output as the factory setup.As such, installing our front kit on your car will only have a negligible impact on brake bias.In most cases, the shift in brake bias is only in the 2-3% range.To put that in perspective, installing a more aggressive brake pad compound in your factory front calipers would typically have a greater impact on brake bias than installing our front kit while keeping the OEM front pad compound. On most front-engine sports cars, the front brakes are taxed much more heavily than the rear brakes.That's why the front brakes are almost always larger, and why you go through 2-3 sets of front pads and discs for every set of rears you burn up at the track.The fronts do a disproportionate amount of work, and as such, they are the most critical component to upgrade.On many platforms, rear brake upgrades offer diminishing returns.The rear factory components tend to be smaller and lighter than the front components.As such, switching to AP Racing calipers and discs don't usually offer the dramatic unsprung weight savings that they do on the front. Since the rears tend to not run as hot, simply running good race pads and stainless steel lines on the rear will solve or prevent any rear brake issues. On a rear-engine car, the rear brakes do a proportionately higher amount of work than on a front-engine car. As such, brake wear tends to be more balanced on the front and rear, and rear upgrades can be more relatively more important to the overall system performance. |
