Re: Q's for the KW Experts

Peter can you clarify - Did you mean "Pax should have more toe-out than my settings"?

It is true that the front wheels of a FWD car tend to *toe-in* under power.
Probably poly bushes reduce that effect slightly - good point I forgot about that!
So yes he could have slightly more toe-out I suppose, this would lead to the figures that PAx's dealer had - which seem fairly sane to me.

However I think Pax would still be fine with the settings since
when my first coilover kit was fitted by AD I didn't actually have poly bushes on the front and AD specified slighty less front toe-out than the (still modest amount) they do now. This was for a more powerful car than standard so it is possible that AD might have been playing a bit safe to maximize straight line stability and later changed to slightly more toe-out to increase turn-in.
The car still handled great though.

For Pax I would say that it is a choice between balancing
tyre life and slightly improved straight-line stability Vs very slightly reduced initial turn-in .

To be honest the GTA turns-in so quickly I don't think a minor reduction affects the handling too much.

Cheers,
TB

A powerfull FWD like the GTA on stock rubber bushes, will create quite a bit of Toe in when the wheels are laden.

I'm not a doctor - but I really do recommend braking later
