jbradfieldApril 6, 2017 at 7:11 pm 5 out of 5 I am the Rockford Fosgate Sales Rep for North, East and West Texas and Oklahoma. We own a Ford Transit Connect, nicknamed “The Mini Sound Lab.” Our Mini Sound Lab is our Rockford Fosgate Demo vehicle, with an extremely loud audio system that includes 6- 15″ Rockford Fosgate Subwoofers. I would estimate close to 800-900lbs of MDF, speakers, amplifiers and wiring in the Transit Connect. I spoke with Mike at a Distributor show and let him know the issues we were having, while driving. He assured me that the addition of SuperSprings would greatly increase the stability, safety and ride, even with that much weight in the back. I bought a set of SuperSprings and I installed them that weekend. Wow! What a difference! No more bouncing, no more leaning! It rides like a brand new vehicle. I am amazed that such a simple product addition can have such a dramatic affect on the ride. Installation was fairly quick and easy. I would highly recommend SuperSprings, as an addition, for everyone that routinely drives or hauls with a heavy load.
