New Set Up for Cooling Front Brakes
inline6 posted a topic in Brakes, Wheels, Suspension and Chassis
I've been working on installing some new brake ducts. I am running the common Xenon Urethane air dam. I was looking at my C6 Corvette Z06 brake ducts a while back and they looked like they might be good for the Z (240 that is). So I took one side off and mocked it up on the Datsun. It fit pretty well, so I ordered a pair. They are about $30 a piece if I remember correctly. I have had them a while, but finally got serious about putting them on because I am getting the car ready for a track event. To fit them, I made some styrofoam forms... One thing I did not know, as this is my first time making fiberglass parts - styrofoam is made from polystyrene. And, standard fiberglass resin is made of some type of styrene as well. That is not good, as the resin reacts with the foam - it "eats" it. Halfway through putting on two layers of cloth, my form was disintegrating. Luckily, I did them one at a time. And for this second one: I bought a can of spray "polyurethane". 6 coats of that on my second form put a layer of "urethane" between the resin and the styrofoam. The second form did not react with the resin. The black you see inside the fiberglass is some high temp silicone that I had on hand to seal the gap between the foam and the air dam - this kept resin from seeping through to the front side of the air dam. It was easy to remove after the resin cured. A bit of laquer thinner poured into the center of the foam and it melted away leaving the fiberglass part. After some clean up with my little air powered belt sander, it was ready for fitment: Not sure yet if I can go full lock on both sides without rubbing, but it looks like I have a chance:
