Short shift / throw shifter



Fits:
Porsche 964 Carrera 2 / Turbo
Porsche 993 Carrera 2 / GT2
2-Wheel Drive vehicles only

This shifter is a game changer! We approached the design of this shifter with the Numeric Racing mindset, and it paid off. This shifter eliminates all the bushings and slop of the stock shifter to give that bolt-action shifting experience Porsche enthusiasts love. The removal of the excessive stock parts makes our shifter 30% lighter too. The shifter is CNC machined from aerospace grade aluminum with stainless steel hardware and includes precision ball bearings to ensure undeniable accuracy. There is absolutely no other like it.

Features:

OEM Fitment: The shifter bolts on easily and directly without any fabrication or modifications! Just remove the stock shift lever, tunnel tube, and forward rod then bolt our shifter right on. Simple and easy install. Nothing required but a few common use tools and red Loctite, although a lift is recommended. The position change in the cabin is no different in the longer throw setting, our shifter will sit and is angled exactly like the stock shifter. In the shorter throw setting, it will sit 1/2" taller than the stock shifter. Also, a plug and play with the Golden Rod or stock shift rod.

Patented Adjustable Throw: Throw reduction of up to 40% (equivalent to 1.1" reduction for each gear). This provides short and crisp throws. No more long and sloppy throws. There is also a longer throw option at 33% reduction on the shift lever, so it is interchangeable based on preference. Here at Numeric Racing, we own the patent for being able to adjust the throw by multiple hole positions on the lever so we can confidently say there is none like it.

Ball Bearings on Every Moving Axis: We remove all bushings and clips that hold the stock shifter in place and bare metal to metal contact for pivot with ball bearings. This is how we can remove all the play from the shifter and provide precise shifts. The forward rod is also eliminated, as that was the old pivot point in the stock shifter and still is in nearly all the other aftermarket options. The problem with that forward rod is that it uses a bushing as the pivot point. It also limits the other shifter options on the market for how short to make the throw because to make the throws shorter, they must lower that rod. But we all know that the rod can only go so low before it will interfere with the heat shield. We do not use the forward rod and that is how we are able to achieve short, crisp throws at 40 and 33 percentage reduction.

All Stainless-Steel Hardware: All hardware is stainless steel, and all aluminum is anodized. Rust will not be a worry with our shifters.

Shift Boot Delete: We partnered with Swine Eleven for the 964/993 shift boot trim panel. The Swine Eleven Re-Boot is a solution for Porsche 964 and 993 owners looking to update their shift knob allowing the factory integrated boot to be removed. This solution is great for those looking to replicate a "Singer Style" shift boot. Order through our website to purchase the ones they tailored to our shifter. If you already have one installed, some slight non-visible modification must be made for it to work with our shifter (contact us).

Transmission Guide Tube Bearing Bracket.
Restore smooth, precise shifting in your classic Porsche with this bearing plate/bracket designed for the guide tube / shift rod assembly. This direct-fit component is compatible with Porsche 964 (1989-94) Carrera 2 and selected 993 (1995-98) manual models.
Engineered to maintain correct alignment and support of the shift linkage, this bearing plate ensures your gear changes remain crisp, reliable and free of slack. A must-have for high-mileage cars, performance upgrades or full restorations.

Fits:

• Porsche 964 (911) C2 1989-93
• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97
• Porsche 993 (911) RS 1994-97
• Porsche 993 (911) C2S 1994-97
• Porsche 993 (911) C4S 1994-97
• Porsche 993 (911) TURBO 1994-96
• Porsche 993 (911) GT2 1994-97
• Porsche 993 (911) TURBO S 1994-97

What This Product Does:

• The guide tube/shift rod assembly transfers your shift lever inputs through a rod or tube to the gearbox selector shaft. The bearing plate/bracket serves as a structural support or mounting interface for that assembly. It ensures the guide tube is located correctly, held securely, and rotates or slides cleanly.
• It helps maintain the correct geometry and alignment of the shift linkage: by keeping the rods/tubes aligned and secured, the transmission engages gears smoothly, with minimal slack or mis-alignment.
  
• Because shifting precision depends on how the linkage is held, a good bracket helps ensure crisp gear changes, correct engagement and minimal wear on adjoining components.

Symptoms Of Wear Or Failure:

• Gear shifter feels sloppy or has excessive movement before engaging a gear — the linkage might flex or mis-align.
  
• Hard or imprecise gear changes — because the guide-tube/rod path is mis-aligned or the bracket is loose, the shift becomes less consistent.
• Noise or rattle around the shift linkage tunnel or transmission area — the bracket may be loose or the bearing surface worn.
• Reduced shift feel especially noticeable in manual gearbox models — less crispness, possible missed engagements or longer travel.
• Visual wear: The mounting holes of the bracket may be elongated, bolts loose, or the bearing surface has scoring, wear, or play.

Why Replacement Or Upgrade Matters:

• Ensures the gearbox linkage works as intended. For high-mileage vehicles or cars used for performance driving, the shift linkage components often endure a lot of movement, and any play in the bracket reduces feel and precision. Replacing the bracket restores the linkage’s structural integrity.
  
• Improves shifting feel & reliability: Especially in classic Porsche manual models (964/993), having tight, well-aligned shift mechanisms contributes strongly to the driving experience. A worn bracket reduces that feel.
• Minimizes secondary wear: If the bracket is loose or misaligned, the shift rod/guide tube may wear more quickly, cause mis-engagements or place additional load on the gearbox. A fresh bracket can help prevent those downstream issues.
• Important for restoration or performance builds: If you’re restoring a 964/993 to better than original or upgrading the gearbox/shift kit, replacing supporting components like this bracket ensures the new components work at their best.

• Porsche 964 (911) C4 1989-93
• Porsche 993 (911) C2 1994-97
• Porsche 993 (911) C4 1994-97
• Porsche 993 (911) RS 1994-97

What This Product Does:

• The guide tube keeps the shift rod / linkage properly aligned, housed, and supported as it transmits motion from the driver’s shift lever to the gearbox internals.
• It prevents the shift rod from bending, mis-aligning or vibrating excessively, which can degrade shift feel or cause mis-engagements.
• A well-fitting guide tube ensures smooth, precise gear changes with minimal slack or bind, contributing to the crisp manual-gearbox feel that many Porsche enthusiasts seek.

Symptoms & Signs Of Wear / Failure:

• Gear shifts feel sloppy or misaligned — the lever has excessive travel or ambiguous engagement.
• Shift linkage noise, rattles or vibration coming from the tunnel / gearbox area due to looseness in the tube or linkage.
• Harder or imprecise gear changes, especially under load or rapid shifts, because the linkage path isn’t firm.
• Visual signs: the tube may be bent, the mountings worn, bushings or bearings inside the tube may be degraded.

Why Replacement Matters:

• Replacing with a new unit ensures the shift linkage remains tight, delivering the precise feel and reliability associated with Porsche manual gearboxes.
• Especially in older vehicles or those modified for performance, the original tube may have suffered from play or wear; replacing it prevents-related issues like sloppy shifts, mis-alignment and accelerated linkage wear.
• The shift-feel of a Porsche manual transmission is part of the driving experience—ensuring the path of shift motion is clean, direct and stable helps retain that.
• Prevents additional wear on the shift rod, guide bearings, bracket or gearbox selector mechanism—if the tube is loose or misaligned, other parts may wear prematurely.
