I entered my truck in a 1/2 mile roll racing event on October 3rd called No Fly Zone in Arizona at the Gila Bend airstrip. My truck is a 2005 ecsb 2wd Silverado LQ9 with turbo and made 708rwhp on the dyno last year. The way my truck sits now I have a drop shackle in the back and decranked my torsion bars in the front to make it sit a little lower (yes it's a 2wd with a torsion bar front end). For tires I have some Nitto 420s 305/50R20. They are only rated for 130mph so I might not be able to run those if the organizers check like it says they do in their rules.

My questions are does anybody have any good wheel and tire recommendations that would feel stable on a truck at what ever speed I'm able to hit in the 1/2 mile and also do well on the quarter mile. Also what can I do from a aerodynamic stand point to help it out a little. Stuff like should I lower it a little more, tailgate up, down, tonneau cover, or no tailgate.

Here are a couple of links to the event if anyone else is interested. I'm hoping to surprise some exotic "supercars" with my old pickup truck and see what she can do.

I ran that event the first time they were out here... the tech is lax as hell... so its what ever you feel comfortable running on... Unless of course this year they get stricter...

 

Just a suggestion but make sure your alignment is spot on. A bed cover and wing will help a lot. Ive been 140+ in a truck and its a little uncertain to say the least.

 

I Know it can get a little hairy from experience myself. I've been well over my 120mph speedo several times. My oh $hit moment came when I thought was about to pass a highway patrol at well over 120, hit the brakes too hard, and put the truck sideways going down the freeway at that speed. First I thought I was gonna die then I thought I was gonna go to jail. Luckily I saved it and the Crown Vic. was retired. After that incident getting on the brakes to slow it down is actually what I'm most concerned with.
