coilovers all the way, they're awesome, much better than regular shocks and springs.
i have gaz gha coilovers and paid £420 for a full set, dampening is adjustable all round. The rear comes with stiff lowered springs uprated shocks, the front is fully hight adjustable however between 25mm and 80mm at least.
i believe AVO do coilovers which are of similar quality and spec but i opted for gaz's as i knew more about them and had seen xr2's with them fitted.
i would highly recommend gaz ones over cheaper alternatives (if they exist).
