Similar story to mine. 4 of us that were into autocrossing and Solo I. One of the guys ended up becoming my best friend and just recently my best man. I had a 1981 Rabbit that I bought in 1984 from an older lady with 17K miles. She must have been cool, because it was a stick. After 3 years as a school car I bought a wrecked 1984 GTI and had the motor bored, added forge pistons, mild cheater cam, match ported head and balanced and blueprinted engine. Car was making about 123 hp with the mild cam and about 130 with the big cam which I only put in for the Solo I events. OK hp to 4 grand, but then it screamed with the bigger cam. Bear in mind this car with a full cage only weighed about 2000lbs with the smaller battery and lighter seat. I added a Quaife limited slip to the trans so you had 99% traction all the time. What made the car competitive against the CRX's was the suspension. We could not buy stiff enough springs, so we had perches machined out of billet aluminum to fit in the stock strut housings that would allow us to run the 2.5 inch id racing springs off a formula car. Stock springs on the GTI were 100lbs. a corner. I was running 200lbs in the front and 250lbs in the rear. That's how you get a front wheel drive car to have neutral handling. If you have never driven a car with a fully bolted in cage, it makes the car feel as if it were machined out of a billet of aluminum. Zero chassis flex. Cool stuff and what a blast. Street legal go cart(before they started checking for the catalytic converter).
