I think the OP has to make an official decision on what car he wants. You can set up a car for both but you also have to think of where you are going to race the car and where your going to drift it. Is it going to be street registered? What are the regs of the class you want to race in etc If its not going to be street registered do you have a trailer and a tow car to take it there? Have you raced before?

my stocko LSD in the nissan locks up and skips the inside wheel when i turn right normally at a T intersection. thats its job!

 

i don't belive for a second that a properly setup, and properly adjusted and worn in aftermarket mechanical KAAZ LSD will "do singles"

 

also ive no idea what yo mean by "....and a spool will push the car rather than let it turn freely". in my limited locker experience, all the locker does is try to straighten the car up. and doesnt let the car turn freely on sharper corners.

 

if the LSD is setup correctly it will lock up when its supposed to, and let it free wheel when it is supposed to.

 

of course, like trev sais, if the lsd has not been setup properly, been slapped together by some bloke in his backyard, not worn in properly. then ive no doubt it wont perform correctly.

 

i just don't think its such a good idea to setup a car with adjustable everything, then go and compromise the entire setup with a locked diff.

 

agreed LSD's are expensive, but you are talking brand new here (a brand new kaaz for a nissan is around 1300, so id assume commondore is the same), and they are a precise mechanical device. don't forget setup costs too, setting all the backlash is not a cheap excercise, and best left to the pro's. (though it can be done, but ive not had the chance to do it myself....i hate the smell of diff oil, and thus will avoid it all costs!)

I have seen a GENUINE KAAZ 2 WAY LSD spin a single wheel, run in corretly, fitted correctly by a diff shop not just a "backyarder", and on the skid pan at qr it spun a single wheel twice in one night :bash:

 

I agree an lsd will always be better for circuit racing hill-climbs blah blah blah, but lsd's wear out over time were a spool wont!, a spool may snap axles, but I'll take paying $25 an axle over $500-1000 to get an LSD tightened

 

I have had afew cars with locked diffs and they take abit of geting used to but once you have a REALLY good understanding of what your car is going to do with a locked diff then you can probably push just as hard as you would with an LSD

 

What I ment by 'Push the car' is when you have a spool in a car or a locked diff, you can't take corners as sharply as you would with an open or LSD car because with a locked diff the wheels turn at exactly the same speed as one another so in turn it FORCES the car to go straight ahead i.e pushes the car
