Raymond,

I don't know the answer to how many IT VW's are shortening their axles. It is said to be needed to avoid puncturing the trans seal and in some cases actually breaking the axle.

Considering that shortened axles are sold by two of the main VW race prep shops on the right coast, I suspect that you'll find a bunch if you go a searching.

I never had or ran shortened axles even though I was warned of the damage I would see. I ran my car at many differing ride heights, some very low(as Greg said it never worked well), and never punctured the seal or broke an axle/CV. Maybe I got lucky. They were just remans and before I sold the car in '01, they had approx 44 race weeeknds or around 100 hours.

As far as how. The shortening, as I understand it, takes place at the most inner end of the axle that can come into contact with the trans seal.
