Thank you all, this has been very helpful. I have done a little racing with some friends at test and tunes, but never anything to this exstent.

MrPbody, that is a good suggestion, and nice to know about the tow truck.

So, this being the first big event for me, should the drag radials be screwed to the rims, or just mounted normally, considering 630hp/tq and a 4200lb car?

If it would be suggested, what is the best method to do this?
