Just don’t google “drag race accidents” before signing up
Only joking! I’ve no idea what they would throw up but will assume some spectacular top fuel dragster wipe outs!
I’ve never done a RWYB session at Santa but have watched plenty when I used to attend some of the (water cooled) VW events there in a past life. Same for the sprint at GTI International.
The strip at Santa had/has a special coating and needs the tyres to be warm for proper traction.
There are proper barriers between the lanes and proper licenced safety measures etc.
Id class the PS4S as decent enough quality to run that class but you might well need to replace the fronts after a few sessions! Some proper race tyres might shave a few hundredths of a second (which is the difference between first and second under race conditions) but not really going to make the blindest difference to a first timer. Reaction times are what it’s about.
It’ll be great fun in a DSG as the car will do all the hard work, all you have to do is perfect your launch control techniques.
As for insurance, what will it actually cover? Not an awful lot I’d imagine but your road car insurance will be nul and void for sure. Unless you get a blowout there’s not a lot to go wrong and I doubt any insurance would cover it in the incredibly unlikely event your car caught fire.
