M series - tracking / camber / caster

[Finn2500m14]

Hi everyone,

Once i have fitted fresh suspension i will be looking to have the car setup properly.

I have the original specs but are camber and caster actually adjustable or are they determined by the chassis.

If that is the case i presume its just tracking the front end.

Thanks, Finn

I was just starting to think about this on my 3000M.
I am going to try 30" tow in .
For the camber i know you can adjust it but i don't know what is best, maybe 1° negative.
Perhaps too much negative camber the car turns in too quick + heavy steering.
I wonder what the experts think

Same as for pretty much every TVR built...

Front... Little bit of neg camber and Little bit of toe in.
Rear.... Little bit of neg Camber and either straight ahead or a tidgey little bit of toe in

A little bit of negative camber is what 1°

I'd go 1.5 deg neg front and 1 on the back.

Should feel very stable at that and not wanting to change directions if you hit a leaf in the road.

Just measured the camber and it's 1.7 ° neg each side.
Does more neg camber make the steering heavier. If i reduced it to 1.5° neg would the steering be lighter.

I would very much doubt that anyone could notice any difference for such a small change, especially on a bushed-suspension road car, that's if it's even possible to adjust/measure that increment accurately.
A psi or two in the front tyres might make more difference!...

Maybe i'll change it to 1° neg then to see

I tried increasing the camber on mine once, didn't feel any noticeable change(although I was preoccupied with a gearbox problem on the day) all I did was ruin a set of fronts on one track day at Aintree.

For mine ( and don't try this at home because I runs different size tyre, rims, solid bushes, ride heights, etc) I have the fronts and rears set up right using a spirit level on the rims with the car with no one in it.
I run the rears parallel, no toe in or out.
And the fronts I have 1.5mm toe in a side measuring back to front of the rims.
