Hey all, just had a quick question. I'm going to soon buy either Tein Basis Z or Advanced Z coilovers to go on my NA. I'll be mounting them with NB tophats, but I just wanted to know if all I need for this coversion is the tophat itself, or all the bushings/ washers/ etc that come with the stock NB suspension. I've read conflicting answers online, so I want to be sure. Either mount the NB tophat on top of what the Tein coilovers come with, or mount them with the associated bushings/ other hardware that come on stock NB suspension? Thanks
