TRANSMISSION MOUNT UPGRADE
986/987




We are excited to announce our new product/service for Upgrading your existing OEM transmission mounts! This is one of the best and least expensive handling modifications you can make to improve your Porsche driving experience, and they work nicely in tandem with our Engine Mount Insert.

As we've all read over and over again, the OEM transmission mounts are a wear item and need replacing after only a couple years of use, due to their rapid deformation. The weakened mounts lead to a loose feeling chassis, imprecise handling, and numb shifter feel. Yet, even new OEM mounts exhibit too much flex to extract maximum performance from your Porsche.

Enter the FUNCTION-FIRST Performance Transmission Mount Upgrade.

We modify your existing OEM trans mounts by gutting and draining their dampening hydraulic fluid, placing them in a jig to restore each mount to its original dimensionality, and filling all the voids, top and bottom, with a carefully selected durable urethane. The result is a rejuvenated and stiffer performance oriented setup, akin to a semi-solid mount – for a fraction of the price. This solution does not alter any structural component of the mount and adds only minimal NVH to preserve a streetable ride.

By limiting undesirable drivetrain movement, you will be rewarded with precise turn-in, planted handling, reduced weight transfer, minimized wheel hop, and direct and confident shifts.


Ordering Options:
1. CORE EXCHANGE - we send you Upgraded Mounts and you return your existing OEM mounts with the included domestic shipping return label and box
2. OUTRIGHT BUY - we send you Upgraded Mounts and you keep your existing OEM mounts
3. MODIFY YOURS - send us your existing OEM mounts and we'll Upgrade those (buyer responsible for shipping to us; 1 week turn-around)

Function-First

Here is some feedback from a 996 owner for the engine mounts, which is essentially the same part and location as the Boxster transmission mounts:

Observations:
I've experienced the same typical observations of people that have swapped motor mounts but I think the degree might be amplified with these in terms of performance.
- Better and more precise shifting(almost like getting a new shifter or bushings)
- Better handling since there is better weight control(it is like getting new shocks to some degree)
- Better threshold braking as more controlled weight transfer allows you to better and effectively modulate the brakes

I've driven this in spirited and relaxed driving environments and in a wide temp range from 35-95deg F.

NVH was very minimal and not noticeable for me(YMMV) since I already had the GT3 coilovers and was used to some amount of roughness.
I would say NVH was more noticeable on first startup in cold weather(below 45 deg) but otherwise for me, was hardly noticeable.

For me the positives far outweigh any negatives that may exist and you have to remember, this is a performance part. I don't understand people that want to corner on rails yet have Cadillac ride(Magnetorheological shocks aside). You're always gonna have to compromise in some aspects in most situations imo.
