Chris Wilson Posted March 24, 2006 Share Posted March 24, 2006 Get a friend to watch the inside rear tyre as you turn, at walking pace, on full lock, in a circle. If the inside wheel is skipping (trying to turn faster than it needs to), you have a tightly set plate type, none stock, LSD. Get used to it or buy a stock type, or a less aggressively set plate one, like a TRD. There's almost certainly nothing you can do except perhaps use an LSD additive. All this assumes it's the REAR tyres that are skipping. is there also a loud banging / rattling as it happens? At above 30 MPH, on anything other than a tight hairpin bend, the LSD should be all but inaudible thosugh, I see you say at ALL speeds.... ???? The wheels are too big, as well Quote Link to comment Share on other sites More sharing options...
Guest hodgson1234 Posted March 24, 2006 Share Posted March 24, 2006 the dif doesnt knock or bang but when you set of from stand still with full lock on the car really jumps badly as if it cant grip i think its def a lsd. it also does it when you reverse in a straight line as if the cogs are slipping? the only way i can describe it is that its like the abs is stuck on?

JohnA Posted March 25, 2006 Share Posted March 25, 2006 So does it feel like there is no differential then? Isn't a hard-core diff a weird choice for a n/a supra? Quote Link to comment Share on other sites More sharing options...
ardasaliah Posted March 25, 2006 Share Posted March 25, 2006 IF your SUPRA is an Auto then the push from the rear wheels, which is always present, can cause sliping on full lock on wet or on salty roads. Mine started to do this when I changed the tyres which don't grip as well as the older pair. I know they are less grippy because the rears also have less grip which is noticable on WOT. Its like ABS pulsating effect. Quote Link to comment Share on other sites More sharing options...

Guest hodgson1234 Posted March 25, 2006 Share Posted March 25, 2006 hard core diff? im new to all this please expand Quote Link to comment Share on other sites More sharing options...
carl0s Posted March 25, 2006 Share Posted March 25, 2006 hard core diff? im new to all this please expand He means any kind of un-shitty diff.. i.e. why would someone put a specialised aggressively-set plate-type lsd on a non-turbo car. I'm not suggesting n/a's are shitty just interpreting for you Quote Link to comment Share on other sites More sharing options...
JohnA Posted March 26, 2006 Share Posted March 26, 2006 He means any kind of un-shitty diff.. yeah, 'hard-core' as in 'men-only', a diff that doesn't really diff:d Totally inappropriate if your mother needs to drive to the stores, but could shave seconds off each lap on a track if you know what you're doing. Race-only stuff. Quote Link to comment Share on other sites More sharing options...
Guest hodgson1234 Posted March 27, 2006 Share Posted March 27, 2006 the faster you go ie up to 30mph the better the car is if i pull away from a junction and go left or right the back wheels jump like they get no grip but if i put the clutch in its fine the car goes round smoothlly no jumping. the slower you go the worse it is especially at walking speed but if you let the clutch of and give it no revs so the car pulls away by letting the clutch out the car doesnt jukmp its weird. i know the car has an upgraded twin plate hks clutch dont know if that helps at all. normal driving i.e 30 upwards going left or right the car is very smooth in a straight line its A1 and pulls very well. I think the car has been messed with in japan and i will have to live with it or sell it i think thank you all for your help im sure the car has LSD? regards Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 27, 2006 Share Posted March 27, 2006 It sounds like its a clutch problem, I have changed 4 HKS twin plates, either for my own uprated stock clutch, or a Giken twin plate package, as the owners (quite rightly, IMO) couldn't live with the dradful clutch judder. The OS Giken twin plate in my Skyline drives almost like a stock clurch, my uprated single platers drive exactly like a stock clutch. Unless, by some miracle, you have got all the considerable amount of bits that are binned when fitting the HKS clutch, it's pretty expensive putting another clutch in a MKIV. I keep alll the required bits on the shelf though. Quote Link to comment Share on other sites More sharing options...
