Is there a "proper" way to figure out what coils I need for my 4 linked rear? Do I need to weight the thing, then make a decision based on spring rates? Or can I just get some TJ coils in whatever length I need? No coilovers for now....or atleast not till I hit the lottery. I'd like to see some pictures of 4 link set-ups on K5/K10 frames....Anyone?
