Race weight was 3408 lbs

Usually when I run one of the benz's in the past it has been a bit colder.

1st pass was just getting used to it
2nd pass was a bit better but it felt like it had a bit more in it
3rd run I spun a bit



I bet with a bit more practice.... and keeping the front tire psi the same on all runs I would have had a 14.4 run

Car goes back in early November so I wanted to make a couple passes in it.

Hmmmmm, what benz to get next????

Why would you keep lowering the psi in the fronts? If anything you should have been raising it....
