So I changed the pads back from the carbotech track pads I had in today....

I would tend to agree. The long straights allow time for things to cool off.
I only used one set of DTC-70's for all three days and I'm not shy about using my brakes. I had plenty of pad left for another day. To compare, at Blackhawk, I will go through one set in 2.5 days. Mike knows Blackhawk - it's a much shorter track with more hectic braking zones and not nuch time for things to cool.
The uneven wear is probably the inner pad. Get some more air in there with ducting or by removing the inboard splash shield.

i'm speaking relative to other tracks...vir isnt hard on brakes...
doesnt really matter which car...i used to track my 3600 lb (without driver) S4 there with stock brake setup (with good pads and fluid) and it wasnt hard on brakes...if you are killing pads at vir, you have some sort of problem (like bad compound choice, etc, ect)...
tracks like cmp and other tight/technical tracks tend to be hard on brakes, since there is usually no real time to cool the brakes...
there are only 2 real brake zones at vir with PLENTY of time for the brakes to cool in between...

Looks like I used about 1/3 of the pad material...
Here are the pads from the left front (they were the same as those on the right). I saw even wear on the inboard and outboard pads.

Here's one of the Carbotech pads (top) compared to my relatively new Hawk HPS (bottom).

I definitely didn't see the same kind of wear as you.

You probably have some room to work with...Every time I take off my belly pan, I marvel at the
amount of crap they managed to cram into such a small space. Unfortunately, it doesn't leave a whole lot of room for anything else...namely, brake ducts.
Good luck with the project. I'm sure you'll have a LOT more success.

I've been thinking/researching ducting as well...
Over on the Tech Article side someone has writen <a href="https://www.audiworld.com/tech/wheel27.shtml">something up</a> on ducting for B5. That's what I'm sort of using for ideas. Aircraft Spruce has these <a href="http://aircraftspruce.com/catalog/appages/ductflanges.php">Aluminum flanges</a>, and some piping. Riveting the flange to the OEM inboard dust shield.
The part I'm still figuring out is coming up with a nice clean way for the air intake ports. I want to keep my fog lights operational. I've narrowed it down to:
(1) NACA ducts on the underside of the belly pan at same location as the RS4. (RS4 pan doesn't fit A4 easily, someone @ brakes forum already tried. Plus there's no connection for piping.) Upside is it won't affect ground clearance. But belly pan needs to be cut/mod and also the piping needs to be easily disconnect-able for when the pan is removed for service (AND w/o it inadvertantly disconnecting on its own.)
(2) long thin rectangular airscoops that hangs down below the belly pan into the free stream, and connects to round ducting outlet. Besides reduced ground clearance, I haven't been able to find a source for these scoops. Prob will need to be home fab sheet metal.
Let me know what you find. I'll be more than happy to share and compare notes!

Sperry.... it's caus you had to haul Drew around half the time...
... LOL
Seriously though, that looks like abnormal wear. The uneven wear may suggest that the pad is binding somehow. I cant remember how the caliper guides are setup on your car.. but make sure those are greased up and that where the pad "ears" make contact with the caliper are clean and free from dust/debris.
Other than that, driving style can also play a role, however, I dont think it would play THAT much of a role. I'll have to talk to Drew and see how your braking inputs were
Just as a point of reference, I used XP12s all weekend with barely any wear. I have brake ducting/cooling and was carring on avg. 3000lbs
