Thanks guys! I just went and read and re-read the 2008 rules and see that you are right WD40, so I'm now going with the 40 series. Thanks all, I'll let you know how I do this weekend on them.
Does anyone have any suggestions what-so-ever as to a starting air pressure for these? And should I get them mounted on the car and put some street miles on them before I head out to the race on sunday as a sort of a break in?
