MY 2000 si has KYB GR2's w/ neuspeed springs, (kinda old) stock sway in the rear. I am hearing a popping noise when i go over small pumps, any idea where this might be coming from? I am only hearing this in the rear of my car
ive read your post 3 times and personally cant figure out what it would be but i would double check everything back that and make sure everything is torqued down tight and make sure your springs are secure in the perch.. etc.
I figured out the problem.It was my rear sway bar end link bushings. I removed the dinky stock sway bar and added an oldschool Neuspeed 22mm +1 4 me lol j/k
