Categories? Well, should we just say the fastest is the fastest? If you are going to split the times into categories, then why not rwd, fwd, 4wd, 4cyl, 6cyl, 8cyl, etc. Thats similar to how the actual competitive drag racing records are kept is it not? Anyhow, Id be happy to break 15 with my atmo 20v and lsd. We will find out next month i hope.
