This Mustang is receiving a upgraded rear suspension purchased from Ridetech. The ride height of your car is also lowered after installation; improving ride quality and handling eliminating the typical soft ride changing to a firmer, controlled ride for performance driving. This car already had the front kit installed which the customer stated lowered the car an overall 2 inches but he could already feel the difference in handling. We are looking forward to getting his feedback when the rear is installed.
