What are peoples ideas on this? Front and rear toe? Starting point recomendations?

 

Rick my Toe settings are as follows.

+0°02' Front Toe

-1°08' Rear Toe

Hope that helps

 

B8,could you please tell us why you have those settings????What handling charactoristic's do they give the S2???I havent really much of a clue myself and any explanation would be usefull,regards Micky

 

Micky Id love to be able to explain! Im still learning myself.

I'll have a shot though.

1stly this description of TOE will help.

TOE
Look down at your feet and turn them inward so your toes are closer together than your heels -- this is called "toe-in".

Now make your toes further apart than your heels -- this is called "toe-out".

In wheel alignment, "toe" is much the same.

Positive toe (or toe-in) describes that the forward edges of the front wheels are closer together than the rearward edges when the wheels are viewed from above the vehicle.

Similarly, negative toe (or toe-out) has the forward edges further apart than the rearward edges.



In effect the Front Toe in my own set up is +0degree and 1min each side.

Giveing a Total Toe of +0 degrees and 2mins Total Toe.......

Very close to being straight.

The reason for the Toe Out on the rear is to remove understeer from the car.

(1) [ ] (2) (5) [ ] (6)

(3) \ / (4) (7) / \ (8)



^^Exagerated examples

1-2-3-4 = Current Setup. 5-6-7-8 normal setup.

Using 1-2-3-4. When turning right (2) & (4) will be loaded with weight from the turn. Weight will ease off (1) and (3).

In effect what is happening is by running -Toe(Toe Out) on the rear of the car, turn in is quickened and understeer is drasticaly cut, as (4) assists in the turn rather than forceing understeer to occur.

With settings in 5-6-7-8 understeer would be promoted in the same right turn (8) being loaded causeing forces towards(5) in turn needing further steering input.

I hope this helps maybee not the most straight forward way of explaining, but the best I can think of.

 

how do you adjust the rear toe on a standard s2 then ,do you need adjustabe tie arms?

 

Ideally yes - but, u can do it with washers - but it'sa pain.


Andy - how do u find the straight line stability with rear toe out?

Taking the car to the Nurburgring in April, there is going to be a lot of high speed driving - i drive a lot on the mway here too.

Rick.

 

Rick,thanks for the info,found it very clear and informative .Regards Micky

 

Mine is still a bit of a c unt to drive but I haven't got round to getting it set up yet.

 

Rick for the Ring my previous settings which were +0°25' (rear) not as wild and a lot more stable at speed would be my personal choice.

Although I recon somewhere between +0°25' (previous setting) and -1°08' (current setting) will be the sort of charactaristics Im ultimately after.

+0°25' was idea for stability whilst at speed and felt reasonable whilst cornering. A good yet safe starting point i was informed during 1st set up.

cool. ive got a little toe in at the rear at the moment, so will try going neutral.

 

so a standard set up ,has the rear wheels(standard tie bars)(s2),at toe in(looking at the rear of the car"forward directional!"so to speak),and the front set at 0 ie,neutral.

~ therefore,in both of these cases ,what would the result do to handling?

1.rear set up as above,with front wheels set at toe -in.

2.rear set up as above,with front wheels set at toe-out.

please

 

simple rule is this: Toe out gives greater turn in, and promotes oversteer - toe in makes the car less eagar to turn into bends, but gives good straight line stability at speed
