Caster/Camber plates. May 13, 2015, 01:32:50 PM I know they're out there, but do I really need them. I'm lowered on SN-95 springs, and I've got something like 2 degrees negative camber. As you can imagine, on grooved roads, the car can be entertaining to drive with 245/45ZR17's. Has anybody got experience with the factory plates? How much correction have you managed to get from adjusting them?
