Cheers guys for the input, but I don't suppose anyone has gone from a basic geo done at a specialist to a full Geo and noticed a great deal of difference?

Depends what you mean by "full" geo. If this just means caster then the difference will be minimal. You can do this yourself as it's normal just to max it out (2 washers either side is normal, 3 rear one front is maxed out if you're using standard bushes) If "full" geo involves corner weighting, bump / rebound setting etc etc the difference will be more pronounced.

 

 

exactly, the real question is would you "need" a full geo based on what you are going to use it for.

I'm not convinced increasing the castor is a good idea personally, it can dull the steering feel as the wheels want to self-align too much.

 

Some of the best handling cars (like Alfas in the 70s and 80s) had almost no camber for instance.

Static or on bump?

Ooops, yes I meant caster in the second sentence of posting #22, sorry.

Another thing is that switching to semi-slick tyres (sometimes with lower profiles) means that the side walls may flex and bend far less. This is partly due to less sidewall height, stronger carcass, more plies etc etc. As a result when cornering (in theory) you need less camber, as the tyre is far more rigid. In practice though if you get them really hot then the increased friction may allow you to pull more G, thus meaning you need extra camber. Anyway my point is the change of tyre and way your drive can greatly influence the way your should set the car up.
