n boost Posted September 1, 2007 Share Posted September 1, 2007 hi guys. On my supes if i drop a gear to slow down my back end twitches everytime as i release the clutch. Is this standard and anybody here have same effect? When i bought the car it was used as a drift car so don't know if been changed. Link to comment Share on other sites More sharing options...
tDR Posted September 1, 2007 Share Posted September 1, 2007 Sounds like you have an aggressive 2-way mechanical LSD fitted like a kaaz. By twictching do you mean the back wheels are locking? I could do this with a downchange in my auto with TRD 2-way but have to shift manually. Do you hear any noises from the diff? Cheers, Brian.

Nic Posted September 1, 2007 Share Posted September 1, 2007 hi guys. On my supes if i drop a gear to slow down my back end twitches everytime as i release the clutch. Is this standard and anybody here have same effect? When i bought the car it was used as a drift car so don't know if been changed. Sound to me like you are simply changing down to a low gear at speed (ie. aggressively changing down from 3rd to 2nd) and releasing the clutch, if you do this then you can get the rear wheels breaking traction.

Guest DaveWilko Posted September 1, 2007 Share Posted September 1, 2007 Did the UK TT auto come with a Torsen LSD? Mine has rubbish tyres at the back (previous owner penny pinching) and pulling out of junctions in the wet is very 'interesting' lol. Slightly too much throttle and i'm twirling the wheel and looking out the side window. Makes me think mine probably has the LSD. The traction control doesn't seem to do much though I haven't spun the wheels longer than a few seconds. Link to comment Share on other sites More sharing options...
Guest DaveWilko Posted September 1, 2007 Share Posted September 1, 2007 Oh and its much more fun with a LSD. You do get much more traction and even if it is more lively going round corners at least you aren't spinning all the power away through one wheel. With both spinning you are still maintaining forward motion, even if it is sometimes sideways hehe. Did that make sense? Link to comment Share on other sites More sharing options...
Spoony Posted September 1, 2007 Author Share Posted September 1, 2007 isnt it better to give more power to the wheel with trcation instead of locking?? Link to comment Share on other sites More sharing options...

I could do this with a downchange in my auto with TRD 2-way but have to shift manually. Do you hear any noises from the diff? I do hear an odd light clunk/judder if i pull out a tight bend/junction, or doing a 3 point turn. Yes it feels like the wheels are locking as i can sometimes hear the tyres screech and it only happens on down changes at around 4k rpm and above. It can easily send you sideways when it doe's this.....Loads of fun. Also i find that i get plenty traction on the straights. Link to comment Share on other sites More sharing options...

Sounds like it could be a 2-way LSD, no chance of asking the previous owner? Be careful lifting off with a 2-way as it can catch people out.

n boost Posted September 3, 2007 Share Posted September 3, 2007 The previous owner is eating sushi somewhere in japan. I am the first owner here and the company i bought it off thought the intercooler was a rad, so picked up a bit off a bargain. Link to comment Share on other sites More sharing options...

Guest yoshi_v300 Posted September 4, 2007 Share Posted September 4, 2007 I fitted a Cusco LSD 2-way to my car. The difference was unbelievable. Traction is just plain crazy, I could chase down Lotus cars thru the twisties much more easily. At partial throttle it locks beautifully to give you mega grip at the back. Downsides are of course when it breaks traction it will lose grip on 2-wheels even if 1-wheel only loses grip. It also vibrates on 90-degree turns as it trys to get grip. But when it does get grip on 90-degrees it spins and screeches away like it's some sort of high horsepower animal, good gimmick. Don't fit TRD etc. etc. diffs. They are made by Hitachi and are not a patch on Cusco or Kaaz. It should be noted also that install requires one-time use only bolts and to setup properly you will probably have to install, drive it, then re-install with adjustment to get it perfect. Proper installation is critical. Done incorrectly the diff will chew itself to death. My mechanic disassembled the brand new diff and re-built it prior to install to ensure it was A1. For most people, a 1.5way is ideal for circuit driving. I chose a 2-way on advice from my Jap tuner which is better for drifting, but superb for circuit use also. With the 2-way the car will drive a little bit like a 'forklift truck' and understeer. But you soon get used to that and the dividends are worth it in my opinion.

Thorin Posted September 4, 2007 Share Posted September 4, 2007 Good explanation Yoshi... Don't fit TRD etc. etc. diffs. They are made by Hitachi and are not a patch on Cusco or Kaaz. ...I have to disagree here though. Horses for courses and all that, I personally wouldn't want a 2-way diff on a road car, the TRD is a good compromise and very tame on the road. It's also less likely to catch people out and therefore safer for most people. Link to comment Share on other sites More sharing options...
Guest yoshi_v300 Posted September 4, 2007 Share Posted September 4, 2007 It'll only catch you out if you give it way too much throttle on a wet road and the car isn't straight. Open diff, torsen diff, 1.5 or 2 way will still spit you off the road if you break traction. Link to comment Share on other sites More sharing options...

Guest yoshi_v300 Posted September 4, 2007 Share Posted September 4, 2007 With a 2-way lifting off the throttle has more of a chance to unbalance the car. True, if you've locked the diff up fully it will 'pop'. But for most street driving thru the twisties, throttle is not fully depressed so when you come off it's not so bad. You shouldn't be lifting off thru cornes anyway. I found the 2-way no problem to drive once you get used to it...the 90 degree turns are the worst thing. You can even brake round corners too, which dispelled the typical 2-way myth that straight line braking is not advise. A 1.5 way is good also. But whatever way the diff is set, how tight it is will determine it's unforgivingness. Link to comment Share on other sites More sharing options...
n boost Posted September 5, 2007 Share Posted September 5, 2007 Mine does's the same on tight 90 degree turns. It screeches and vibrates. I love the diff the way it is and find straight line traction great. Link to comment Share on other sites More sharing options...
Guest yoshi_v300 Posted September 5, 2007 Share Posted September 5, 2007 Yup, the traction from the apex onwards is nuts. Even at 1/4 or 1/3 throttle you can feel it grip the road like nothing on earth! I only got the full potential at circuit - through Duffus dips at Knockhill it was crazy and on the Nurburgring the traction out of the corners at full throttle was amazing. My auto allows me to coast out the first part of the 90 degree turn and small throttle just to coast me...which reduces the vibration. The diff has downsides, but it's worth it for when you get it on dry tarmac. I chased a WRX round the circuit for 2 laps in the stinking wet proving you can drive it in the wet conditions. But it does pop and shake the back end when you come off the power in wet weather. Link to comment Share on other sites More sharing options...
Nic Posted September 5, 2007 Share Posted September 5, 2007 This is probably a question for CW, are there any advantages in using an LSD using Carbon plates? ATS a Japanese manufacturer make carbon LSD and clutches for the Supra http://64.233.179.104/translate_c?hl=en&u=http://www.a-t-s.co.jp/02lsd/character/index.html&prev=/search%3Fq%3Dhttp://www.a-t-s.co.jp/02lsd/carbon/index.html%26hl%3Den%26safe%3Doff%26client%3Dsafari%26rls%3Den http://www.a-t-s.co.jp/02lsd/character/img/carbonlsd.gif Link to comment Share on other sites More sharing options...
tDR Posted September 5, 2007 Share Posted September 5, 2007 I guess the wear rate is a lot less Nic, and it may not make so much noise as some normal clutch plate type 2 way diffs - that's the difference carbon in clutches apparently makes anyways, looking at the Tilton and RPS Carbon/Carbon. Nothing wrong with the TRD diff for traction BTW yoshi, mine is great down a backroad and is very different from driving a car with an open or torsen LSD. I get a little wheel hop on 90deg turns but nothing major - at all other times the TRD does not make its presence known other than through great traction. Cheers, Brian.

Guest yoshi_v300 Posted September 5, 2007 Share Posted September 5, 2007 My cusco is fine, you don't know it's there until you do a 90 degree or you put the power on and feel IMMENSE grip levels Link to comment Share on other sites More sharing options...
