I know this thread is super old, but I just wanted to comment on the above post: I ran into the same problem, so I had a friend of mine weld a piece of bar stock (maybe it was key stock) into the slot on the OEM scissor jack so that the resulting indentation is only about a quarter inch. Now when I jack the car up, the weight is transferred through the welded-in piece to the jack, and the jack doesn't contact my V1 side underwings.

 

How does it work? Have you been on the track with it yet?

 

Nah I just use it at home, couple times per year to change out my wheels or do other minor work. I don't worry about the welded in piece breaking, but I do worry about some other parts breaking. That thing makes all sorts of unhappy noise when I crank on it.
