C-bag when I was stationed in Furth Germany we had a small track at Montieth Barracks VWs were the only things ran.
3 of us went together one winter and built our car in my motor-pool Rather as it turns out I think I did most of the build like the near perfectly match parting the little 1200CC to the point that it had the output of a 1500 duel carb, constructing the roll bar out of very lightweight chrome-molly tubing cutting nearly 120 lbs out of the safety cage alone. Every bit of the body was sanded by Fred and Dave to the point of being less than half the thickness of a stock Vdub. They ground and stripped away every ounce of superfluous metal
The VWs had a unique front suspension in that addition to having cross mounted torsion bars the control arms trailed vertically inline with the front to rear of the body the whole assembly is held on to the center frame by 4 bolts. I skewed the front end with the Right tire 1 1/2 inches in front of the left then twisted the control arms on the right to give it nearly 15° negative camber and the left side to have 10° positive camber then bent the spindles, down for the right and up for the left a few degrees . with the right torsion rod tightened to raise that side and the left loosened to lower the left. Doing this changed the castor to more positive on the right and slightly negative on the left The rules allowed for running 3 different sized tires but the steer tires had to be the same size.
When the season started in the Spring with Dave as the driver our car, his qualifying lap broke the all time track record in any class by 3 seconds. I don't think anyone in the association had ever actually sat down and calculated the effects of staging or re-cambering the front end like I had. It was my belief that if the front tires were properly adjusted and tweaked to fit the turns while maintaining minimal straight line rolling resistance that even though not powered they would actually help to pull the vehicle leaving the rear tires to just push By setting the car up to have as much inward lean as possible the poorly banked turns were not nearly as hazardous.
