Traction issues

The tyre issue is the big one - Those 17" low profile tyres have no footprint under load, they don't "spread" and are also a pretty hard compound.

Fit drag radials and the sidewalls "bag", you get a bigger footprint, and the softer compound sticks better also.

You may not need Caltracs - there are plenty of 500 HP cars sticking on good tyres, spring clamps and SS springs.
