Alright so. Out working on my Miata suspension today. The rear end of the car sat lower than the front on the adjustable coil overs. The rear was also pretty cambered. So, I adjusted the rear coil overs all the way to the top to match the fronts. Then while adjusting the camber, I noticed that it was set at the stock settings, yet the rear was cambered. So, I adjusted the camber all the way out. Rear still has slight camber, but much less extreme.
Then on my test drive, every little bump made me feel like a bobble head, and every larger bump made a sound so loud I thought the rear end was coming out from under the car.
So my thoughts are this. The reason that the rear is still cambered is because the car is still several inches below stock. Lowering the car on the suspension = pushing the bottoms of the rear tires outward?
Secondly, the reason for the loud noises when hitting bumps I believe is from the coils being raised all the way up, making the suspension much stiffer and giving it less travel over all.
My solution is replacing the 3" top hats all the way around with the stock top hats (Which are roughly 1.5 inches shorter), then adjusting the coil overs all the way around further down to sit at its current height, but giving the suspension more travel and softening it. Now I'm pretty tired, so before jumping into this does this sound like sound reasoning to anybody else?
