I'm hoping to avoid additional NVH by using the STI trans mount instead of the Group N. I've also heard that rear diff mount inserts can help.

Engine mounts are tough. All the aftermarket ones are way too ****ing stiff and the Group N's from the BRZ are pretty expensive.

I got the Perrin pitch stop brace as soon as I saw that my 2017 didn't have the revised mount. It's pretty solid on the driver side, but I'm slightly concerned about the perrin pitch stop brace on the passenger side of the mount. It's only help to the chassis/firewall via two aluminum rivet nuts which are, frankly, weaker than I'm comfortable with. Unfortunately I just couldn't find stainless steel rivet nuts that would fit

Apparently the Perrin brace will repair broken mounts they say...


jokes aside. I plan to get the Perrin pitch stop, engine and trans mounts when I have $1k to spend on it haha.

All in all I'm stage 3 for the last 18.5k miles not a single issue!! My end links and some of my cusco bracing is a bit rusted, yet just cosmetic. I track the car and drive super hard this is also used as a daily driver. That Perrin mount brace is prob. Overkill to tell you the truth. You will be fine. I prefer Perrin quality over group N and customer service is the best at Perrin!!
Thanks for this review. I was wondering about the rest of the ride quality after stiffening up everything.

road noise is already loud, so now we have the engine and trans noise to worry about!

how about vibrations? it would seem that all this stiffening would cause more vibrations inside the car.

Do not use SS rivet nuts,there is a reason why we use aluminum.
The aluminum ones are plenty strong, the force that is applied to the nuts is not enough to cause an issue. Additionally if they strip out or do not crush properly while installing them you will not be able to get the SS ones out easily compared to the aluminum ones, as well as if you ever have to remove them the aluminum ones can just be pulled out with some needle nose pliers.

Sorry not sure what you mean? but the PERRIN Pitch stop brace is NOT made to fix a crack or broken bracket, it is a preventive maintenance part.

I must have misinterpreted your website?

quoted from the site:

"The PERRIN Pitch Stop Brace does exactly what its name implies, it reinforces the brackets that connect the pitch stop to the car. The factory brackets on the firewall that hold the pitch stop in place will bend and snap off, even with the flimsy and soft factory pitch stop bushings. The PERRIN Pitch Stop Brace will act as both a means of preventing your pitch stop brackets from tearing as well as reattaching the pitch stop to the firewall if your brackets have already failed.[1] "

Either way I was trolling a bit to get discussion started....as I wouldnt use this to reattach if it broke....

I might also mention that I plan on getting one for my car...since I really like your all's stuff


even if my personal opinion is that they are a bit too pricey for me...Speaking of which...do you all have discounts for Nasioc members?

I installed a pitch stop brace (Perrin) on my 2015 WRX - fairly easy install - also added solid pitch stop while I had TMIC off

I'm looking to install the group N pitch stop in my 2018 WRX. Is this safe to do so without Perrin's brace on vehicles with the revised mount, or is it still too early to tell?

Will the Group N engine mounts from STi for the BRS (FA 20) motor work on a WRX?

Default Pitch stop mount bracket cracked

I have the same issue with my 04 wrx where the bracket on the fire wall is cracked and its causing a metal tinging sound when I shift gears. I know theres a reinforcement for the 15+ but I cant find one for the bobble eye. Is there a aftermarket bracket for the 02+? If not, how well with it hold up if I weld it. I was told by a couple members from central ohio subarus to weld it up but I dont know if it will hold up very well. The car is about 98% stock with no tune

the bracket can be replaced, its a better bet than welding it. i dont have the part # for it, but here is a pic of what the current gen one looks like.

Okay, same problem. Not covered. Going to attach new bracket with blind rivets or blind bolts.

I just purchased a 2017 wrx and noticed this issue, cracked pitch stop bracket, the next day. I've read all these posts. What's seems to be the repair for this? How is it holding up for those who have had it happen in the past years? Looking at the technical service bulletin on subispeeds website, does the motor snd trans have to come out? I assume the dealer will not cover with EGR,TGV deletes, intake, accessport, and an exhaust!
Any follow up information would be appreciated.

Was your pitch stop bracket cracked? If so, how did you repair? Did you leave it damaged and depend on upgrading the other mounts?

OK so your pitch stop BRACKET failed? Or your pitch stop MOUNT failed? You are not being clear. I assume the former, which is worst case.

The place you purchased the car from, assuming it's a dealership, should fix it under warranty. If you bought it privately, warranties still carry over.

no it wasn't cracked but i prevented from happening by replacing the stock pitch mount. with less movement, less likely that bracket would snap. but isn't yours still covered under warranty?

It is but I assume they will immediately deny the claim due to the modifications.

not really. it's a common issue and there is a service bulletin on it. they should cover it under warranty. and yeah....it's unfortunate and they may have to take the engine out to replace the bracket.

Has anyone else got this covered under warranty with similar modifications? I know the starter of this thread stated his dealership was going to pay for half.

I think you want to do the opposite. You want to transfer less force to the pitch stop bracket by using a softer pitch stop. If you put in a stiffer bushing, that will transfer more forces to the bracket itself instead of letting the bushings take the vibrations.

Installing the group N engine and trans mounts should help by stiffening the overall engine/trans.

The warranty will most likely be reviewed on a case by case basis. If they see you've modified the vehicle (e.g., tuned and increased hp), I wouldn't be surprised if they denied your broken pitch stop bracket.
