If you want one of the biggest suspension bang-for-your-buck upgrades for an S550 or S650 Mustang,start with the cradle. The factory rubber bushings are great for a soft ride, butthey also let the rear cradle move under load.Not the best for performance handling. OurStage-1 Cradle Lockout Kit nearly eliminates that deflection, helping reduce wheel hop, improve 60-foot times, and make the car feel more predictable without adding noticeable noise, vibration or harshness.
