PITCH STOP MOUNT
Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop mount. The factory pitch stop mount is designed to control the pitching of the engine and transmission under light to normal acceleration. Subaru's with power and drivetrain upgrades will need PERRIN's more aggressive option.
What does a pitch stop mount do?
Under hard acceleration, the drivetrain is being twisted front to back from front axle torque twist. To control this front to back twisting, Subaru created a pitch stop mount. The factory pitch stop is made of plastic with soft rubber bushings, allowing for a significant amount of movement under hard driving conditions, creating drivetrain slop & shudder.
Why Do I Need The PERRIN Pitch Stop Mount?
The PERRIN Pitch Stop mount controls the movement of the drivetrain in both on and off throttle driving giving the driver a more positive feel and literally putting more power to the wheels by eliminating lost energy.
Construction
The PERRIN Pitch Stop Mounts body is machined from 6061 billet aluminum and features a combination of 90a and 70a durometer. The bushings are as stiff as possible without introducing excessive NVH. (noise vibration harshness)
5 Year Warranty
PERRIN Performance warrants to the original purchaser, all PERRIN products to be free from defects in material and workmanship within a sixty (60) months period from the date of manufacture. *Some exclusions apply

Satisfying
By 17 Forester March 14, 2018Before finding SubiSpeed, I had asked Perrin if my 17 Forester had a pitch stop, the guy who I asked wasn't even sure himself. Anyways... 3rd gear always had a pretty noticeable vibration that felt uncomfy. The moment I installed the pitch stop, it has become a slight vibration. If I had to put a rating, probably took 90% of the vibration away. The other gears almost nothing.

Well worth it
By Spencer February 14, 2018More direct feel of power and no wheelspin, even when road is wet. Gives you more of that raw feeling when going flat out.

Great Product
By Mych June 18, 2017Nicely packaged and instructions were clear. I also used Subispeed's install video for additional insight and install views. Product was a little difficult to get installed (had trouble aligning both top and bottom holes with mounting points). Once lined up it was a piece of cake, and torquing it down was easy given the amount of space in the area. I installed the mount along with Perrin's brace. Shifts feel more direct and "cleaner". Acceleration and direction change feels sharp. Only 'downfall' is additional drivetrain noise, but it's barely noticeable. All in all it's a great product. I would recommend it for enthusiasts and people looking for reassurance, alike.

Solid
By Aaron March 1, 2017Feels and looks better than stock. Great peace of mind when matched with the pitch stop brace. Easy to install overall.

Solid piece
By Andrew October 28, 2016Overall seems solid. Although i did realize many 2015 wrxs are having issues with pitch stop mounts breaking the bracket so I will be picking up the perrin brace as well just for peace of mind.

Noticed the difference right away
By Jordan November 15, 2015I could feel my engine moving around while driving around normal in my 2015 sti and decided to give this a try. After replacing the stock pitch stop mount which is actually made of plastic yes plastic with the perrin pitch stop mount you could feel an improvement right away. The throttle response is better and the car just feel more solid. It should have come like this from the factory. I also dId not notice any extra noise after installing the mount as well. I would definitely recommend this product.

Nice Build, Better Engine Response
By Tim September 22, 2015When I received this pitch stop mount, I was pleasantly surprised with the overall build quality. It is very sturdy and significantly larger than the OEM mount. I had some issues getting it installed, mainly because of the much larger bushings. This made it harder to squeeze the mount in and line it up for the bolts. My advice is to not be afraid of using as much of the provided grease as needed. Once I got it installed though, the improvement was noticeable as soon as I started driving. The car responds much quicker and smoother, especially under harder driving. I'd definitely recommend getting this mount.

Pleasantly Surprised
By Leland August 10, 2015I was pleasantly surprised at the noticeable difference this made after install. It's not a night and day difference but you could feel it in acceleration and I believe handling also. The car didn't seem to want to 'push' as hard as it did before also it seemed to transition a little easier in immediate change of directions. The car (2015 WRX CVT) suspension was all stock when this was installed. Quality part at a reasonable price and easy install.
