Edit: No answers? Fine, I'll ask the evening crew.
Ok, this one is slightly above my suspension knowledge. The Seven has 450lb coolers in the front, worn-out, cut OEM Miata springs in the back. I was mocking you'll the rear fenders, and realize that the suspension will have to be limited go two inches of travel. It can have all the droop in the world, but after two inches of travel, it will contact the fenders. I know that the cheap and amateur way is to put thick neoprene bump stops so it'll run on the bump stops, but what's the correct way of fixing this? I'm looking out for a set of mildly used rear adjustable coilovers for the Miata.
