The car:- 2wd Cosworth

Mods:-
Adjustable TCA's
AVO Coilovers

I would like to know the best settings for the above two items for a road and also some track sessions going quick in straight line but needs to hold the road for bends and twists.

Future mods will be some sort of adjustable rear end. I would like to fit Mag works rear end but need more info on what brakes are needed? If a std type exhaust will fit and clear the mag arms? How would you have a handbrake other than hydrolic? + Anything else that could effect the fittment.

Any helps would be great Thanks in advance.
