Don't you like ATB's ? I've run both and apart from the racket when parking with the plate type , couldn't discern a difference. Rob.

Hi Rob, a friend of mine does a lot of rallying,(i know it's a different application)and warned me off them so i'm just taking advice from whoever at the moment.

Please educate me. Plate? ATB?

There are several manufacturers of limited slip differentials. Two main methods of limiting the slip between the two driven wheels which normally would have no drive on one side to allow for tight slow turning. The oldest has been around for a very long time and consists of a plate in the diff' which will drive both wheels depending on the spring pressure put on them. So these can be adjusted to the weight of the vehicle and it's intended use i.e. tarmac or loose surface. Mine was set at 40 ft/lbs measured at the wheel and served me very well although very click clacky when turning/reversing at walking pace. Also if not adjusted correctly can give you more understeer for obvious reasons --- she only wants to go straight ahead !
Then there is the ATB made by Quaife which is controlled by gears but cannot be adjusted. Much less savage in operation and therefore , in theory , less likely to give understeer . Completely silent in any situation and said to be better for light cars. However , I changed to ATB years ago and noticed no advantage nor disadvantage over the plate type I sold. Interestingly the guy I sold it to was rallying and had tried the ATB but wanted to go back to a plate type --------- so I assume a plate type suits loose surface better cos they're normally opposite locking before every corner anyway SO understeer isn't a problem but max ' grip is all important.

Trans ex make one but not sure of the method of operation . Andy Bailey has one in his Blue Stylus SBD XE 235BHP I think ?

That's it Kev' ------ the limit of my knowledge on these bits of kit

I really don't know why i did'nt ask you first Rob, i think my mate said he blew a few ATB's up and advised against them, if you say theres no difference in your experience then i will go for an ATB, it saves a lot of work messing about with the plates. I'm currently building a rear axle, i want to fit rear discs any info on calipers and disc size.

Talk to Tim on rear calipers , I'm on drums cos they don't work very hard anyway which means you'll have to fit a balance bar or a valve. Get the front right ie. disc size/alloy calipers/nice pads(not EBC) , I use HAWKE BLACK then the rears simply stablise the car under braking. The front does 90 percent of the work. Tim has experience with disc set ups on light cars and he'll have it all off pat --- probably the bits as well.
