Just to add to this, I installed s14 front coils, Fully threaded body for individual height adjustment.
Measured the fender arch height of 26" before install after install had a height of 24 1/2"
Stiffer ride on 10k springs, less body roll. Camber plates are a great addition handling wise.
They perform well, but I'm not worried about performance as much as some of you are as I am going for a custom look. One future problem that I can see is the front lower control arm is very close to hitting the body of the car and the lower I go the closer it'll be.
