S1 rear wheel toe in

[Trefhead]

Does anyone have the data for the toe in for the rear wheels for an S1.

Also I have put Gas Gold aluminium coilers on and have a set of S3 trailing arms to go on as they are adjustable. Anybody got any advice for me

Cheers

Sit tight, there will be someone along shortly. Have you tried the "search" facility? I was under the impression that the trailing arm of the S1 wasn't adjustable so I'm guessing that's why you're fitting the later ones.

If that's the case then why not get the existing fixed setup measured at an alignment centre and then replicate the settings when you fit the new trailing arms?

Because there is pretty no chance that the wheel geometry is still good on a 30-years-old car.

Haynes value is toe-in +0.25+/-0.25 degree. (It comes from "TVR S Series NEW Alternative Parts List")

The first post (from 2020!) will tell you what you want to know.
Otherwise, there's much more info in further posts.

It wants a tiny amount of toe-in. It isn't particularly sensitive to the amount because the camber/toe settings swing all over the place anyway due to the semi-trailing geometry, but I use about a quarter of a degree total toe-in plus about 0.1 degrees per degree of camber at normal ride height as a rough guide.

This is a good and brief watch - explains why you need a small amount of toe-in on the rear.
