i got BC coilovers on my classic wagon that were for the saloon. would recommend them. New they were about £650 if I remember correctly.
The thing to remember though is that if you lowerthe car, you need the roll center correction kit really. You can leave the dampers set quite stiff or use stiffer springs to hide the fact that your roll center has been raised, but if you lower the car at all, you raise the roll center and actually increase body roll.

that being said, mine is lowered and I don't have the roll centre correction kit installed, but it's on my "to do" list when funds allow
