The classic Mustang chassis presents some unique challenges in terms of updating its suspension. The factory configuration has issues with camber gain, roll center height and migration, and bump steer, to name a few. The traditional fix has been with new parts that bolt into the existing factory structures. We can make some pretty impressive gains with this type of system but we`re still limited in the scope of the designs, and we still have to deal with the big, intrusive shock towers crowding the engine bay.
