i have read alot of discussion's/arguments on the subject of locked diffs. i have 2 cars with lockers, my vh and my celica heres my findings to no surprise there is an increase in tyre wear. obviously the rear but also the front as when u turn sharply the rear wants to go straight and the front is trying to turn and causes the tyres to roll under the wheel etc...also slight increase on the turning circle because of this. any1 that says there is no increase in wear is lying! its obvious...when u turn sharp u can see skid marks from your tyres, thats rubber peoples!! driving in the wet...to me makes it no more dangerous...if u do try to induce some oversteer and ur inexperienced i can see how it can be dangerous but thats your own fault...in saying that it is a hell of alot easier to hold it out sideways as u can predict what's going to happen and control it (i recommend keeping this activity to the track!!) Diff lash! and annoying noises! this is annoying! unless u get your diff properly shimmed etc it will cluck around when u turn sharp with no load (eg, clutch in) the commodore is ok cuz its auto there always load on the diff but u can still hear it sometimes. once u get up to speed u dont even notice it most the time. over time i have started to notice random noises from the rear that didnt used to be there, id say my bushes are starting to flog out from the stresses. i locked the celica diff just to see what its like and i am putting an open center diff back in this weekend as its annoying me too much and its a daily driver. the commodore diff was locked purely for traction as i was sick of spinning a wheel off the line. anyways thats just what i have found over the months of having lockers, peace!
