The next step in extending pad and rotor life was getting some cooling into the front brakes. For whatever reason there is absolutely no ducting to the brakes on the M3...even my lowly 2001 540i had ducts that shot some ambient air in the general direction of the hub.
I picked up some aluminum backing plates that use a 2" inlet. They needed minor massaging to bolt up, but protect the tie rod ends from heat fairly well.

I adapted the 2" inlet to 2.5" hose with an off the shelf exhaust adapter and bolted it all up.
For the fresh air inlet, I cut holes in the face of the undertray and bolted up 3D printed ducts made by a member on the E9X Track and Race Discussion FB group.
Clearance is good, it's very close at full lock with 275/35/18s by the subframe but I used a few extra zip ties to suck in the duct and oval it where it was close to the tire.
Fresh rubber - love these tires for their endurance, durability, and price point.
