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!

You haven't really given much to go on. Do you mean pad choice, noise, dust seals?

Here is a link about pad choices and the potential noise.

Works wonderfully with DS2500 pads. No louder than stock.

Edit: you do get the reverse clunk but it's minor, and doesn't bother me.

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.

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?

With a little searching you would find your answer. The weight savings are noted in the link

No dust boots on these in the link above so not best suited to DD / all season use surely ?

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:

Our CP9660/372mm brake kit weights vs. OEM M2 Blue and M2C Silver brakes:

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.

If you're unsure which type of kit is right for you, check out our page, "Which type of AP Racing brake kit is right for me?"

Regardless of how you plan to use your car, we have a great solution for you.
