Call Afco also
I really like my new Afco double adjustable coil overs(36 different settings) on the front of my S/P car that I remove a set of older Koni steel coil overs, new best 60 ft. 1.24 at Yakima, WA compared to a old best of 1.27 at Woodburn, OR last year with the old Koni. The D.A. at Woodburn was right at 2000 ft. lower also
Al Aquirre recommend them over Koni, Santuffs and the other custom expensive brand name that I can't remember right now
Better price and better results
