I finally got a chance to work on my car again xD. Took me awhile though because i had to take existing items inside my car apart. I can say the B-Stock helps out a lot!!! My air compressors use to rattle like crazy . They are so quiet sometimes I barely notice the compressors are on. When i air out my air ride no noise at all, scared me for a bit . Will probably purchase more later down the road, right now finances are tight. got to pay to play that's for sure.
