Thanks guys a lot of great info. but now I'm really confused and will have to measure the arms to clarify what I have.

Do the S1 and S2/3 arms look much different?

I ask as the GF manual says the chassis is designed for S2/3 suspension, I have vented front brakes and S2/3 lower arm and am guessing the original constructors would have followed the guidance of GF. They may have unwittingly bought S1 uppers, can this be decided just by visual inspection?

If it proves I have S1 uppers, I gather I can still achieve a suitable set up, is this correct?

Given I will have to look at the rear as well at some time, why do you recomment rear toe in?

What effect does it appear to have/cause to these cars?

How much toe in have you guys used on the rear?

At least I know for sure that my rear brakes are S2/3 I have an old receipt for their repair!

Cheers
