I did a quick search and didn't see anything about this so here goes.
Last time I took my 1G to the local road course I melted the front brakes off of it and they were good high temp pads. I wanted to take my 2G to the same track but didn't want to end up with the same results. Both cars are running 2 piston front calipers with outlander rotors and brackets. I looked at some options and couldn't find a good way to route hose around the axles and would still need to fab a new backing plate. I saw many cars how oem wings/deflectors attached to the lower control arm to divert air running under the car toward the center of the wheel to help cool the brakes. The biggest duct I could find of this style is off of a Porsche GT3 model. The parts were surprisingly cheap from my local Porsche dealer, ebay was more expensive
. The part numbers I used were
997-341-484-92
997-341-483-92
The ducts are designed to snap around the stock lower Porsche arm so they required a little trimming to fit the DSM lower arm. I wasn't able to figure out a way to re-use the clips on the duct and ended up using zip ties to hold the duct to the arm. It sounds ghetto I know but I was looking for a quick fix the night before the event and it turns out they held on fine. I drove the car to and from the track at 80 mph and hit 130 mph on track and they are still on the car. I don't have direct before and after results but I didn't experience any brake fade during this track day so they must have had a positive effect. I was using pretty cheap pads as well (stoptech performance pads) and they still have good meat left. Take a look at the pics and let me know if you have any questions, hopefully this can help somebody out. I spent less than $20 on this mod
