Chucky_waR Posted February 12, 2012 Share Posted February 12, 2012 How does one stop the rear end stepping out when accelerating? For example if I'm in third and I put the hammer the back end twitches to the right. I have the boost down to 1.3 bar and can't accelerate in 2nd and need to be careful in third gear or I loose rear. Now my question is for you big single turbo boys and girls. How do you accelerate without loosing the rear end but still manage to get the power down? And is normal for the supra to always kick to the right? I want to drive her properly but needs some advise. Link to comment Share on other sites More sharing options...
JamieP Posted February 12, 2012 Share Posted February 12, 2012 Best quality and biggest tyres you can get under the arches, avoid very low profile tyres and 19" wheels, good geometry setup. Link to comment Share on other sites More sharing options...
Neil-NA Posted February 12, 2012 Share Posted February 12, 2012 Mines NA and always kicks to the left, just figured it was the camber of the road. Link to comment Share on other sites More sharing options...
Westy Posted February 12, 2012 Share Posted February 12, 2012 Have you had a full geometry set up done on the car!? May be something slightly out of line!? What tyres are you running as these could be a strong contender!? Link to comment Share on other sites More sharing options...

heckler Posted February 12, 2012 Share Posted February 12, 2012 and check you tyre pressures too! Link to comment Share on other sites More sharing options...
Wez Posted February 12, 2012 Share Posted February 12, 2012 Decent suspension, geometry and rubber Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted February 12, 2012 Share Posted February 12, 2012 big wide arches, decent quality wide rubber and a decent geo setup..... thats the PROPER way anyway. Decent geo setup and decent tyres will do the trick though Link to comment Share on other sites More sharing options...
TRD-Rob Posted February 12, 2012 Share Posted February 12, 2012 I had the geo setup and good tyres on but I've always had a problem with my back end stepping out,as Darryl will know Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2012 Share Posted February 12, 2012 Check your tyre pressures first then move on from there Link to comment Share on other sites More sharing options...
Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 Let go and get the tyre size.... I have not taken her yet for a geo setup but was told by Phil Boase when I bought her that it was done. She has HKS adjustable coilovers but has been adjusted since I bought her in september.. I'm going to pop outside and check the tyre size.. Back in a sec.. Link to comment Share on other sites More sharing options...
Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 The rear tyres are Pzero rosso 285 / 35 / 18 97Y Link to comment Share on other sites More sharing options...
Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 Where can I take her for a good geo setup..? And is the above tyre and size ok or is the profile to low? Link to comment Share on other sites More sharing options...
dude Posted February 12, 2012 Share Posted February 12, 2012 Phil Boase also told you it had a built motor, to be fair even a stock TT will step out in this temp, the tyres will never reach their operating temp as the road itself is too cold, this is why winter tyres work better they are designed to be used under 8 degrees, even a sportsbike will have more grip on a touring tyre than the latest chewing gum compound sports tyre because they are designed to work at slower speeds and colder temp. Even the best rubber is useless with all the salt and grit spread at the moment so just take it easy and wait a couple of months or get some driving lessons from JP, he deals with this on a daily basis. Or fit a syvecs with TC. Link to comment Share on other sites More sharing options...
Spence Posted February 12, 2012 Share Posted February 12, 2012 Go with contis or n rated tyres from a Porsche. Don't like pirrellis at all. Link to comment Share on other sites More sharing options...
Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 Hi dude.. This even happened on day one back in September. I took it easy yesterday as the motor has just been rebuild and the roads were very slippery but now that I have her back I want to learn to control her better.

dude Posted February 12, 2012 Share Posted February 12, 2012 IMO unless you run a decent TC you need to accept the fact it will step out and learn to drive around it, the real prob is when it does it for no reason like over disel etc , I know that when I floor pretty much any single car in 2nd its not goinf to be pointing dead straight so allow for it.

Tyres also deterorate with age Pete, they go 'off' get hard etc, maybe do the 30-130 day where you can learn the car better, unless the road cambers a lot they are pretty controlable as they have a long wheelbase, just blag a go with JP if you need to learn how to control one.

See if you can book an airfield day to have a go at controlling different conditions in a safe environment. Link to comment Share on other sites More sharing options...
johnny g Posted February 12, 2012 Share Posted February 12, 2012 As above with sensible tyres and a good make, but also look into a decent diff like a TRD or Giken, and be progressive on your throttle. Link to comment Share on other sites More sharing options...
JamieP Posted February 12, 2012 Share Posted February 12, 2012 Yeah as Johnny says a good LSD might be worth looking towards, tyre size is fine, dont drop to a 30 profile, id put some R888's on it come the spring and do the geo setup. Link to comment Share on other sites More sharing options...
Lbm Posted February 12, 2012 Share Posted February 12, 2012 Would the constant application of pedal through the floor with a heavy right foot with a turbo'd car contribute to the problem? or is it more the tyres and set up in the op's case?

adam1983 Posted February 12, 2012 Share Posted February 12, 2012 Probably a really daft question but what would you guys say is the right tyre pressure? I just tend to go with 34 all round but never really given it too much thought until I read this. Link to comment Share on other sites More sharing options...

Also depends on how hard the turbo comes on boost. Link to comment Share on other sites More sharing options...

I just tend to go with 34 all round but never really given it too much thought until I read this. Stock UK is 36 front and rear. I keep mine around 34-36, i try to keep them exactly the same from side to side. With my car being a weekend toy i check them everytime i use it.
