Shifter Cable Ends

The OEM shifter cables use large rubber ends to isolate the shifter from the transmission. These soak up your effort and numb the feedback and directness required for optimal shifting performance. The resultant sloppy gear engagement leaves the driver questioning if the desired gear is fully engaged and leads to over-extension and stressing of the cables as the shift lever is pulled beyond the limit. From a safety and reliability standpoint – the plastic snap-on cups wear out over time and split, causing the cable to pop off the transmission.

This replaces the rubber and plastic internals of the OEM shifter cable ends with tight tolerance aluminum and Delrin components.  The result is excellent shift feel, precision and control with no added NVH and no chance for the cable ends to pop off.

Installation is simple – just snip out the OEM shifter cable end internals and bolt in the upgraded units. The existing cables do not have to come out for the install, so the entire process can be done from below the car.

This upgrade is an excellent accompaniment to our SHIFT-RIGHT Solution ball bearing shifter kit to deliver the ultimate in shifting performance and reliability.

NOTE:  Installation is not reversible, as the OEM cable end internals are cut out to install the new cable ends.

Transmission Mount Inserts 


The OEM transmission mount was designed for ride comfort and is prone to sagging and tearing – and is detriment to performance. The empty voids allow for too much transmission movement, resulting in sloppy handling, numbed responsiveness, and imprecise shifting. Race cars utilize a solid metal mount, which is impractical for street use as it transfers excessive noise and vibration into the cabin.

These durable urethane inserts simply slide in to fill and fortify the empty voids of the OEM mount, preventing premature bushing wear and undesirable transmission movement with minimal added noise and vibration.

Handling is taut and predictable; power delivery is smooth; gear changes are crisp.

Installation can be completed with basic hand tools in about an hour. Removing the stock transmission mount bushing is NOT necessary.

Choose between three hardness levels:
1. TRACK (80A) – for optimized performance on track and race-cars
2. HP STREET (70A) – for tuned and sport-oriented high performance street cars
3. SOFT (60A) – for added performance and to preserve the OEM bushing


a) Although the inserts help prevent OEM bushing from tearing, if the bushing is already torn, it will need to be replaced. The inserts serve as a supplement to a good bushing.
b) In some cases of extreme bushing sagging, a vise or C-clamp with adequate silicone based lubrication will aid in installation of the inserts.
c) The 996 series bushings have a tendency to distort and sag over time.
d) For 996 GT and Turbo applications, please make sure that you are ordering the correct insert for your transmission mount. Occasionally previous owners with failed OEM trans mounts replaced them with 997 bushings, which is different than the 996 turbo bushing.
e) The OEM bushing is shown for illustrative purposes only and is not included with the Transmission Mount Insert

Shift Knobs

The factory shift knob is often overlooked as a source of sloppiness, but it shouldn’t be – comprised of rubber and plastic, the OEM knob separates and numbs the driver from the mechanicals.


The Shift Knobs are machined from solid billet aluminum or Delrin to ensure that all shifting effort is transferred to the shifter. The 2 inch diameter knob fits firmly in the palm, with the circumferential cutout providing dexterity and enhancing grip. The shaft is designed specifically to fit Porsche’s rectangular shifter, attaching securely via high-hold set screws, and allows for seamless integration of the OEM shift boot.

The knob threads onto the aluminum base shaft, and is available in 2 materials:
1. Aluminum – machined from a solid billet and anodized, this knob offers added weight for confident shifts
2. Delrin – impervious to extreme temperatures, the lower weight of this knob yields faster shifts

Shift pattern engraving and custom paint in the engraving is also offered for an added OEM look.

NOTE: Fitment is for Manual Transmission vehicles only. The Classic Shift Knob is designed to work with the OEM shifter – some aftermarket shifters may require minor modification for proper fitment, please contact us for details. Purchase price includes 1 shaft, 1 knob, and mounting hardware.

Lackluster shifting performance on a stock turbo can be attributed to the worn plastic bushings and pivot connections utilized in the shifter assembly. As these bushings require loose tolerances and free play to prevent binding up, they generate sloppy shifter feel. Moreover, the plastic and rubber construction flexes excessively which causes spongy gear engagement, especially on older turbos.


The SHIFT-RIGHT Solution replaces plastic bushings with ball bearings, eliminating flex and excess play that normally plagues the stock setup. Shifter feel is sharpened and gears engage with certainty.

The kit is comprised of custom machined aluminum pieces, heavy-duty enclosed ball bearings, and hardware to entirely upgrade the factory shifter assembly. Additionally, the tightly toleranced shifter yoke is hard anodized for maximum wear protection and Teflon impregnated to further reduce friction. The OEM cradle and shift lever are retained with this setup so that shifter throw remains unchanged and the factory fit is preserved.

The SHIFT-RIGHT Solution is compatible with the Turbo OEM shifter, as well as most aftermarket short shift kits. Please contact us to confirm fitment for your particular aftermarket short shift kit.

NOTE:  Fitment is for Manual Transmission vehicles only. Choose model based on the type of shifter installed in your car, not necessarily your car model (ie. some 996 turbos have 997 turbo shifters installed).
