Both of my S550's will receive mechanical Mods for this coming season. My 2016 GT/CS mods are as follows: Steeda rear sway bar load adjustable, Steeda subframe IRS connectors, Roush Performance pedal kit, Steeda Extreme G Trac K member brace, Ford Racing Sport cat back with x pipe, Ford Racing Show parts custom lighted door sills, JLT catch can, JLT custom painted engine and coil covers. My 2015 GT will receive a new Steeda front & rear sway bar kit load adjustable & a base line "DYNO RUN" on the Realspeed dyno. Curious to see the stock numbers with 1200 plus miles on my GT. These mods will be installed by Realspeed Automotive . They have done MOD installs on all of my Mustangs .The results were fantastic.................. MODS..................season 2016
