Don't waste your time , as this is not an area that gets proper air flow. Woodhouse designed a brake ducting system years ago that got ton of air on the calipers/rotors, and then the indominatible Henry " I am Proud to be Anal," Cone came up with a kit that is a wonder to behold. It is downright pretty and well finished ,even though no one can see it. The Famous Paul Mumford built two flugle horns to protrude out the nose of his ACR to finally capture air, and he joked that his Horny Air Intake looked like and orchestra coming down the straights. Cone's adaptation of Woodhouse's idea is the most effective on the market, as it forces air onto the brake components at the highest pressure zone.
This is the number one item to keep your brake fluid from boiling, giving your brake pads double the life , as well as decreasing rotor wear.
I ran through 3 sets of pads at Mid Ohio in 2000, and yet one year later with this system ( albiet the one we designed initially ) on a faster car, I made it through the entire weekend , a practice day for the next Viper Days event, and one morning track sesssion. The initial figure is a bit high to some, but you will get it all back in less than one year of events.
