Anybody using brake ducting?

The car sounds fine the way it is, maybe some cross-drilled rotors and your set :up:

Cross-drilled rotors are 100% no-no. You want mass, and no "focus" on which to start cracks.

Blank rotors from a well respected supplier and proper track pads - (HT10, PF01/06, and ducts if you feel you overheat the brakes.

The car is being prepped for track use and while it's down i'd like to put the brake cooling set up in.

I still haven't tracked it first hand so i can't say if the brakes do hold up. The previous owner didn't mention brake fade or failures. OTOH he gave me 3 boxes of pads and which is why i'm running the HP+s for a while.

The bimmerforums search was pretty fruitless, i didn't find a whole lot of e30 tech or pictures. I did see a ghetto fabulous hose clamp around the strut holding a hose clamp on the duct hose which if all else fails i'll have to try. Then i'll just need to make a flange to connect the hose to the vent. My valence looks just like the one on your 85 325e Jgood, minus the lip.

I don't care about noise or dust, but i want to be able to make the 20 minute trip to the local track without swapping pads. Can i do this with the HT10's or pf6's? Longer trips would be made on a trailer.

Agreed.

You can drive to/from the track on HT10's, but they'll be rather noisy. PFC 01 or 06 pads are not nearly as noisy and are, in my opinion, a better track/race pad than the HT10 pads.

If I was sufficiently inspired, I'd jack up a corner of the 38 car and get a picture of the cooling ducts. Maybe later...

I'd appreciate it very much, there's no hurry as the car is in and out of the shop till the weekend.

If I get home when it is still light tonight, I'll get a picture for you.
