Colby DuVerger

Okay so I need some serious help.. I've been looking for a decent full set of coilovers for my '85 Z31 and I have had no luck finding any "bolt-in" coilovers for anything under a grand! (Not willing to drop a grand on coilovers). I keep seeing EVERYTHING for the Z32's and I understand they are a more popular car but I've been looking at some S13 conversion kits and even those run a over couple hundred bucks ontop of the S13 coilovers I now have to buy..

If anyone can suggest a company that makes coilovers for Z31's under a grand or even another budget route, that would be greatly appreciated👌
