I'm forced into XP, so I'm only running against a couple of people. Looking to do time trials next year with lots of track days.
No, no, no. You're not forced to run XP, you're
privileged to run XP. XP is where the cool guys hang out. None of that mamby-pamby street tire stuff for us. We also don't bother spending hour after hour wondering if that new NGK spark plug is a legal mod. Welcome to the XP club, Dude.

BTW, I've also found that magnets do quite poorly on some of our XP cars. For temporary numbers, I found the Reusable Vinyl to work much better for me than the static cling. The static clings tended to have trouble when it started raining.
The reusable stuff tends to get some dirt buildup on the leading edge of the sticky side over time, but it's no big deal. It is basically a thicker vinyl stock that has a little less "stick", so it holds it's shape well when you peel it off. I think I might still have a roll of White Reusable stuff in my garage that you can have for free if you want it. I'll look tonight when I get home.
