So I was planning to cut into the dust shields and mount a flange there, like Modshack's Audi pictures here: http://www.the370z.com/diy-section-d...tml#post101626.
I'm thinking I'll probably have a friend with some metal working equipment (proper cutters, a plasma cutter if necc) help with cutting the right-sized hole in the dust shield, and then just rivet a flange into there, aiming for as close to the center as possible (at least, far enough in that the air is mostly being drawn through the center of the rotor rather than dumping on the back surface of it). I'll try to get some pics when we get to this. |
The dust shield blocks air to the hub pretty significantly. Cutting a hole in the dust shield shouldn't be too difficult, I think I'll just use the dremel. For now I think I'm just going to strip the fender liner all together, run a 3" duct with 2" reducer and come up with a way to direct the air through the gap between the caliper and the hub (probably use a 2" metal coupling and beat on one end with a hammer). Unfortunately with the AP Racing caliper bracket to offset the caliper the gap is even tighter. You also have to deal with the fact that everything moves when you turn the wheel.
Not sure if I'll get this done by my next track day on Memorial day, but we'll see. It's a short track with 3 heavy braking zones and not a lot of time for cooling. Either way I'll have rotor temp paint and caliper temperature gauges installed. I'll be using 1800F MOT Sintered track pads.
