My 1990 is pretty low on raceland ultimo coilovers. 15x7 205-50-r15. I aligned it and was only able to get the rear to -3 camber. I'm wondering if I need to buy camber bolts or plates or whatever to fix this. I ultimately want to have a low stance (not slammed) without this negative camber. Also, what are specs for a good handling miata, I hear that factory specs are what you need to aim for but what are other people running for good handling? Thanks!
