Toe in or out?

I know most seem to have toe in,

but my query is ..

toe in = stability in a straight line
toe out = better cornering/response

is this right?

If so - i have no issues regarding stability but would like the best cornering performance

Does this mean i want to go for a toe out set up?

Any help/opinions on this are needed and appreciated

Thanks

I don;t agree with the toe -out Statement

I thought (think) toe out is dangerous.

Camber adjustment on the rear will help with corner response as well helping car either grip road or oversteer. (different thread I feel)

On the rear suspension toe out introduced by the suspension being compressed is usually very undesirable, on on the front toe out may be useful depending on suspension set up, tyres etc.

Hi at the front bump steer will also need looking at. No point running toe out if you have loads of toe out added in bump and roll.

Also toe out on the front is usually the bodge way of adding ackermans angle to the front when cortina uprights are fitted. The sierra uprights do not have the same issues as cortina in this area of the geo setup.

Cheers Matt

As above but simplified

Cortina Uprights = Toe out
Sierra Uprights = Toe in

If you wan't quasi ackerman in turns move the steeeing rack mountings rearwards a bit, then reset the toe in to 1/16" to 0 (across both wheels)

I wouldn't put toe out on ANY rear drive car. I have cortina uprights and I run 0°30' toe in, with very satisfactory results.

I have a Hunter laser system and set up several cars a week, mainly Audi's, but we have all the boyracers in to sort out their scoobies etc.

Only set rear wheel toe if you want outrageous oversteer at very low speeds, on rear double wishbone setups, you can dial in quite large amounts of toe in without any detriment to the ride or tyre wear.





If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation
