Minimize Deflection and Improve Handling. Granatelli Motor Sports (GMS) created their Mustang Motor Mounts with two objectives in mind. The first is to dramatically reduce the engine deflection and drive line movement found with the stock mounts to increase engine response. The second is to drop the motor lower in the engine bay which lowers the center of gravity for improved handling performance. These two benefits make GMS Motor Mounts ideal for spirited street, track and race drivers.

Minimize Driveline Deflection. The stock OE motor mounts found on the S550 Mustangs use soft rubber bushings. These rubber bushings allow for engine and drive line movement which is fine for a soft comfortable ride, but not for the spirited driver. GMS Motor Mounts use high grade polyurethane bushings to reduce this excessive driveline and engine deflection, which results in an increase in engine response, quicker reaction times and more accurate shifts.

Improves Handling Performance. Granatelli Motor Sports engineered their Motor Mounts to drop your Mustang's engine 0.520 inches lower to the ground, effectively lowering its center of gravity. A lower center of gravity will make your Mustang much more stable, especially while taking a turn and will greatly improve its overall handling performance.

Quality Construction. GMS proudly manufactures their Motor Mounts right here in the USA. The mounting plate itself is constructed from carbon steel for superior strength, while the spacers are CNC-machined from high quality billet aluminum for light weight and durability. Lighter and stronger than the stock rubber and steel mounts, these GMS Motor Mounts will provide years of trouble free driving performance.

Polyurethane Bushings. Granatelli Motor Sports designed their Motor Mounts using Energy Suspension polyurethane bushings. The included polyurethane bushings are considerably stiffer than the soft factory rubber bushings for a dramatic increase in handling performance. While being stiffer than stock you will see a negligible increase in NVH (Noise, Vibration and Harshness).

Application. This Granatelli Motor Sports Motor Mount Kit is designed to fit the 2015 to 2018 Mustangs including the V6, GT and Shelby GT350 models. Does not fit EcoBoost.

What the description says is all true :)

I didn't see a drop of the motor by .520" like it said. I placed a gt350 tower strut bar and a c brace. Clearance looks the same as before. But the engine is more precise and shifting is sooo seamless. V6 auto.

Mind blowing!

I drive a manual v6 mustang and I was coming across the common problem of shifting from 1-2 and 2-3 when driving hard. A buddy of mine had recommended that I upgrade my mounts to reduce engine movement. After researching a TON online, I couldn't find much about people talking about mounts for the s550, not many reviews on here either. So when I had come across these, I decided to go for it. Install took about 3 hours at a local garage, probably could've been quicker but they've never had a 16 model before. The results are amazing! There is some noticeable vibration at idle and when taking off in 1st gear but it's in no way bothersome. 1-2 shifting is improved but still has the smallest amount of stickyness, 2-3 shifts have improved ten fold. Butt dyno tells me there's an obvious amount of power now being sent to the rear wheels, driving like I normally do actually chirped the tires pulling out of the lot with traction control on. I've never had any experience with gms or any other brand that carries motor mounts for the s550's but I'd imagine they all do their job well. For the price I'd say these are top notch. Also lowering the engine the extra 3/4" seemed to make the car feel more planted as I drove over a set of railroad tracks on my daily commute. A lot less body movement. All in all, I would recommend these to any person that has even the slightest thought about upgrading motor mounts. No regrets here!
