FWD Torque Steer problems

[Bazda]

oh true now that i think about it i thought about it the wrong way....

I've heard that extra castor helps reduce torque steer

haha from my experiece more castor makes torque steer worse when i drive my car in the wet. cause i can't get wheelspin when its dry...

That could be the extra toe movement from the change in geometry due to castor adjustors?

Yes, you need to set the bump steer and change the stock rod ends to proper rob ends and move them around. sent you pm on how much you need to drop the arm using my calculations.

ok well there are all sorts of things there for me to look at. I get the car back from paint in two weeks and then its off to speedtech so i will also talk to them

My brothers work send their racecars to a Wheel alignment specialist in Wellington so i will track them down and see what can be dont too

Most cars I did alignments for was toe in, wheels pointing inwards. This gives stability at speed as the tyres are pushing the car together. Toe out creates a very unstable car as the tyres are trying to pull the car apart leading to very twitchy steering.

Also, FWD will never have 'bite under acceleration' as weight transfer under acceleration will be towards the rear. As this transfer happpens, the weight comes off the front wheels which may lead to the wheels going from toe in, to toe out. Being in toe out before this happens will help reduce torque steer, but be aware that the vehicle will feel different.

when boost comes on at 22psi at 355hp the car 'Bites hard right'

[Bazda]

Gong hard right isnt really torque steer, thats another issue.
Torque steer is when it goes left to right like crazy.

[Mr Revhead]

Other way around

[tsoob]

need to drive it really

[Bazda]

Other way around

If it pulls to 1 side only, thats the alignment of either the front or the rear being out of wack.

tsoob had this same experience and managed to find the problem being his rear suspension bushes.

[Mr Revhead]

Yeah that can happen too.
But torque goes one way, not two.

[Bazda]

Fair point.
But not in these cars .

It goes all over the show. Next week i will get someone to follow me and i will video things so you can all see

And nick ..... i will be in Auckland in a couple of months to write a menu for a restaurant up there so we can swap cars for a bit

Might be a silly question but since getting the car back together has it had a wheel alignment at all?

[XSVWGN]

yea it had one recently when i had some new tyres put on

[Mr Ree]

Good luck getting to the bottom of your angry Rolla Matt

P.S Who is painting your car? Im on the hunt for prices from people who have good reputations *wink*

Matt

Bring it to me, i'll do an alignment for you to check it.

Recently Soopachargn had an alignment and they said it was all good. I checked it and they hadnt even touched the rear arms to adjust!, his car was towing out on the rear which made it twitchy.

Some times you gota wonder what these alignment shops do, guess it saves them time if its just out of spec but that will be fine.

[1I1]

I had one place set toe in on one side in the rear and toe out on the other side

hahah you driving up?

be cool to put a face to the name tho bro if you have time..

We can have a bbq with you as the star chef

[CelicaGT8]

Mine does the same thing 3sgte in Rona, hit boost and it can be a bit dodgy when your half way around a corner

[XSVWGN]

haha yea nick no worries ... im sure i can make that happen. Will be driving up to give the wagon a good run in. Baz, when i come up to aucks i will get in touch and get you to look at it ..


Ree ... you have PM

[loose_unit]

I have always run a slight toe out on my GT, there was quite a noticeable difference from having it at 0. Also run whiteline castor kit with as much postive castor as possible. Even with 230kw the torque steer was quite minimal.
