Help me decide..

Ok... I've been thinking about lowering my Z for a while now, but due to the area I couldn't justify lowering it on pure garbage roads without having some way of raising it back up. It occured to me to use airbags, but I don't want to take anything away from the performance of the vehicle. Recently I've found out about cup kits and I've decided to go that route. However I'm caught up between a couple choices in coilovers.

I've narrowed it down to a few...

Stance GR+

Stance Supersport (has a feature that has camber adjustment)

BC Racing ER or BR (ER's have an external resevoir)

Tein Flex or Monoflex

I'm not sure what to go with. As I'm not too familiar with coilovers in general. So I'd like to know what you guys think. Not just about what's popular but what would be the best for ehh.. "street use" and looks and comfort.
