Has any one removed the front brake backing plate(stone guard) to increase air flow to maybe help cool the brakes during track use? I was thinking of doing this in combination with Porsche GT3 brake air guides?

I have taken my 2017 M2 to Chin Track Days at Sebring 14 times since I bought it in Jan 2017. That is about 35 track hours or so. Somewhere between 1500 and 1700 track milea out of 8000 total on the odemeter.

I have been through three sets of OEM front rotors and two sets of OEM pads and one now have Hawk Street/Track pads on third set of OEM rotors up frint.

I have just replaced the rear pads but the rotors are still 8n spec (barely).

This weekend I again roasted the front rotors after only 3 1/2 track days. Prognosis is Hawk Pads overheated OEM rotors. Brake lines have Castrol React SRF and ECS steel braided brake lines so heat tolerable.

BMW in Tampa recommends more airflow as M2 brake cooling ducts are mostly cosmetic.

I have found Pegasas but not many other brake cooling duct kit vendors for M2.

Any suggestions?

I would start by trying what ZM2 did in this thread with Porsche GT3 brake ducts... http://f87.bimmerpost.com/forums/sho...2Bbrake%2Bduct

Thanks for the link post.

Altho, if you’re tracking that much, you may want to go a full duct solution ala Twt or DrKevM5. I found a good deal on a barely used front AP BBK, so I went that direction.

Plus, your calipers are likely to still change color no matter your cooling approach, so it’ll cost you some cash to return the car to stock down the road.
