I would get an LSD but the only one worth getting is the Quaife Helical LSD which costs $1000, not including install. If I'm going to spend money on something I'm going to get the best; not compromise in the short run and lose money down the road. If you are only interested in drag, your money is much better spent on a set of good drag radials for launching. BFG's are good but now I've heard more than one person tell me a blowout story so I'm not so sure if I should get them. There could be issues because I have a friend in Vegas who said he was driving his truck down the strip with new BFG g-forces' when the sidewall of one completely gave out, and he had to fight to stay in control. The PowerFC costs $1000 (not including Datalogit) and the Quaife costs $1000. Between the two I would get the PowerFC and that's what I did. It just arrived Tuesday but I haven't had a chance to try it out yet.
