the jamex ones (coilovers) i can say are pretty decent, iv had mine on 3 years and about 35k miles with nothing but good words to say, they are not expensive, pretty firm ride tho, and if you were not looking to lower your car anyhow, id prob say to you to get uprated shox/springs over the collies mate
you will need top mounts too, forget crap from places like euro car parts, get genuine, add this to your costings....
