Reduce Subframe Movement. The Independent Rear Suspension (IRS) Subframe of the S550 Mustang is infamous for unwanted side to side movement during spirited driving and hard braking. This unwanted subframe movement is caused by the soft, natural rubber bushings installed by Ford at the factory. You can eliminate this unwelcome movement by replacing your original stock bushings with a set of Granatelli Motor Sports Subframe Mount Polyurethane Bushings. After installing a GMS Rear Subframe to Body Bushing Kit you will see a dramatic improvement in handling performance with increased traction and less wheel hop. These GMS Subframe Mount Bushings are a must for any IRS equipped S550 Mustang.

Superb Quality. Granatelli Motor Sports Subframe Mount Bushings are proudly designed and manufactured right here in the USA. These GMS Bushings are injection molded from a high quality low-deflection, 80-durometer polyurethane. A synthetic polymer material, Polyurethane is considerably stiffer and less compliant than your Mustangs original factory rubber bushings making it ideal for spirited driving applications.

Minor Increase in NVH. GMS's Rear Subframe Mount Bushing Kit was designed to decrease bushing and cradle deflection, because of this there will be a slight increase in NVH (Noise, Vibration and Harshness). With only a minor, almost unnoticeable, difference in NVH, this GMS IRS Subframe Bushing Kit is perfectly suited for street, auto cross and race applications.

Application. This Granatelli Motor Sports Rear Subframe Mount Polyurethane Bushing Kit is designed for use on all 2015 to 2017 S550 Mustangs that are equipped with the factory Independent Rear Suspension (IRS), including the V6, EcoBoost, GT and Shelby GT350 models.
