“954 Billet” FI Performance Corvette C5 Transmission Mount

NEW DESIGN - The OEM Corvette transmission mounts are fine for low power C5’s. High HP C5’s that launch hard, the transmission mount is prone to failure. This often reduces traction also creating powertrain shake (sometimes mistaken as wheel hop). With a forced induction C5 throwing the power down and you are really asking for problems.
The 954 Billet Design Transmission Mount set is designed to replace the OE mount and bolts to the differential to keep your powertrain in place reducing the loads on your half-shafts and other driveline components.
Constructed with 6061-T6 aluminum Energy Suspension Bushing / Pads and Steel Bracket for durability, pair this transmission mount with Engine Mounts for an unbeatable package. All necessary hardware is included and this is a direct fit application for all C5 Corvette models.
Note: You are going from a squishy rubber mount to a solid Poly mount, you will notice a slight increase in driveline feel.
You do not need to remove your harmonica dampener on the side of the differential with this new design during installation. Also the brake lines are easier to deal wit.
If there is any question please call or text 203-644-0712.
I've tried 3 different diff mounts. The Lux Mount by SacCity, AMT Double Barrel, and just for the **** of it the Duralast c5 mount. Finally bought this 954 Bullet from FI Performance. In a nutshell the 954 had the least NVH of them all and best of all zero wheel hop even with crappy tires. Thanks Mr. Brian for your vast knowledge on this subject.
I’ve only received my diff brace still waiting for my trans brace only got one tracking number so not too sure about that

Great quality, unfortunately the differential did not make the pass , time for an uprgraded diff lol
Looking forward to putting this to use. Brace went in without issue and was a fairly easy install since I had my drivetrain out for other work. Nice quality product.

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.

Brian was AWESOME to deal with, I changed my mind a few times on what I wanted to do with my c6z.. You can go down an endless rabbit hole when you get into these cars “while I’m in there “He was right there with updating pricing and I couldn’t ask for more.. Parts are parts and they will fail but it’s the service that sets the bar for a big purchase.. I haven’t driven the setup yet as it’s still being built but I’m sure he a phone call away to get it sorted..

Great customer service as always. Was on my doorstep within 48 hrs.

High quality parts with installation pics to come

Great support team helped me get the parts needed and got my order within the week.

Balancer was exactly what I needed. Everything as described and fast shipping. Thanks guys

Team went above and beyond to locate the part needed to get my can back on the road asap.

I finally got to install the intake which literally took 10 minutes. The power and launch difference was insane! You can hear the turbos spooling a lot better as well. I’m amazed by the difference just from the intake

Great product and communication.

I went with the super low, extended rear shocks , Swift 9/7k upgrade and absolutely love the stance and how the truck rides. It’s tight in the corners , smooth driving down the hwy and not bouncy at all. Thanks to Brian for getting me set up.

Completely changed my car

Everything seems in good condition and good quality, appreciate the help from brian for all my questions and to setup the shipping to canada

Brian R. was extremely helpful and spent a good amount of time answering my questions about switching to coilovers. He was a wealth of knowledge and made the purchasing and installation process very easy.
