Im also wanting to do this, after alot of reading and searching on here it seems the TTE/Eibach ones are rated, along with the Teins, I think I heard they can become bouncey though, Im also still a little lost a regarding what should be replaced at the same time, i.e-Bushes, and how to prevent bottoming out etc so any info would be great! Coilovers I think are the way to go but alot more pricey than just replacement springs, not sure if its worth spending another £200 on coilovers as im not going to be taking my 200 on track etc, all we are most likely after is a lower look with as little bounce as possible . . .
