It seems for convential drag cars and hi-po street cars that a detroit locker is the go. This locks both the wheels so you get the maximum grip to propell the beast in a straight line in the quickest time. These locker type diffs are a real pig to drive on the street and can be quite dangerous, especially in the wet.
My question is why don't they use lock diffs that can be turned on and off like some 4WDs and trucks have?

You can modify your diff and install a thing called Lock-Right. (www.powertrax.com) It's a better LSD than the factory ones. There was also another one you could get where you had to drill a hole in the housing for either a vacuum line or some wires dependind on what locker you got. Haven't got any info on that one at the moment, have to hit the books at home and try to find it.

Try ARB (the 4WD mob). They do lockers for 4WDs front and rear axles. <ight have a website - dunno - try www.arb.com.au or something...

Detroit Locker diffs aren't locked all the time, they only lock under power. When you back off, they disengage and give you normal differential action. The new style Detroit Lockers are a lot easier to live with as they don't bang and clang like the old style that was fitted to the Falcon GT-HOs in the 60s and 70s. They aren't dangerous when you get used to driving with them, like getting used to driving with a tight Limmited Slip Diff.
Full and Mini Spools are a different animal altoghether as they are locked 100 % of the time and are a real pain in the arse to drive on the street. The only reason that V8 Supercars can get away with using a spool is they have a great big set of slicks on the front to make the car go round a corner.
