Caldina with 17's wheel alignment

[Lac]

Hey,
Do any of you have good wheel alignment details for a 1997 GTT with 17's. 215/45/17. All new tyres going on tomorrow and want the alignment to be good!

Cheers

Basically factory settings, maybe a tiny little more toe in for the front, 1mm max per side.

Rear factory settings are 1.9mm toe in per side if I remember correctly.

Whats the Factory settings? Ive only seen what people think they are.

When I had my alignment done with new tyres at Firestone they gave me a report with all the specified factory settings next to the before and after measurements... you could ask a place like that? That'll probably not be for 17s though huh

I did a wheel alignment on my brothers Caldina 6 months ago.

I am 90% certain that it was 1.9mm of toe in each side for the rear.

Front setting factory is zero toe. which on most fwd/4wd causes tyre wear on the inner shoulders of the tyres. Which is why I say 1mm max, to combat the inner shoulder wear.

Ive seen these specs?


FRONT
0.5mm toe in
Camber is at .7 deg negative,

Rear

Rear wheels are 2mm toe in,
Camber is at 1.2 deg negative

Well 1/10th of a mm is pretty dam close.

And Like I said, Give it a max of 1 mm of toe in each side for the front and it will be mint

I have always had better results with more camber in the front.
With toyotas stock settings, changing them front to back makes a world of difference! Remeber they are set up to understeer from factory.
Ie in this case 1.7 front and .7 rear.
However these things can depend on the drivers preferences.
Despite pretty much every person doing my alingments saying "you will wear the inside of your tyres out" It has never happened. Instead on the times when I let them do it to stock specs, I wear out the outside edge faster

[B_giB]

That is why I gave them more toe in for the front than the factory settings.

[Mr Revhead]

toe IN on the front?

[B_giB]

Yes

[Mr Revhead]

Can you explain that in detail please?
that goes against everything I have learned/read etc on wheel alignments

Thought slight toe out on the front of 4WD / FWD so that under power wheels go from

I am just saying almost every vehicle I have done a wheel alignment on that has zero toe or up to .5mm toe in has cuased inner tyre wear, only exception to that rule has been Subaru's, for some reason they always wear the outer tread on the front tyres.

When a vehicle with power going to the front wheels causes the front wheels to toe out during acceleration, which loads up the inner tread on the front tyres.

As everyone knows, negative camber loads up the inner tread to, so a combination of the two, equalls more wear on the inner tread.

Where toe-in loads the outer tread, it can counter-act the load from the camber.

Here is interesting document:

http://www.gtfours.co.uk/stuff/download ... _ST165.pdf

Which recommends 0 toe on front and 0.5mm/side toe out on the back, although it is for ST165.

[B_giB]

The back would want to drift all over the place with settings like that

[sergei]

I think slight toe out on the back is sensible as the powered wheel are trying to overtake vehicle and toe-in in the result.

You are thinking about non-powered (RWD) front wheels where they are pushed by the car and resist movement.
In FWD/4WD configuration front wheels pull the vehicle and try to toe in instead.

[1I1]

On FWD's a bit of toe-out on the back can be used to aid turn-in

Well this is what local wheel alignment did to my corolla
