Found a place for mk3 cars
Might be worth a phone call to find out about mk2 cars.
I built my own for my Golf3. I used diamond plate I had laying around but flat/plain aluminum will obviously be cheaper.
An entire sheet of the diamond plate (3/16th thick, 4'x8') was $220 at my local metal supply dealer. Plus I used about $25 worth of sawz-all blades, and a large peice of card board as a template. The sheet is big enough to do 2 skid plates.
I bent it between two trees growing close together. Cut it with 12teeth/inch blades(best). Thick aluminum is easily smoothed if you're looking show quality, so roundinding the edges with a file will be like sanding wood. My plate is intended for protection from leaving the surface of the earth and impacting large rocks that frequently happen in rally-cross. Technically you could locate thinner (1/8th in) aluminum and be safe if you're just doing it for a lowered street car.
