Prekom
Prekom for Porsche
Prekom is a family-run business specialising in steering and suspension parts renovation and manufacturing, with a strong focus on Porsche applications. Their range covers stock replacement steering and suspension components for Porsche models, supplied through Design911.
A Quick Look at Prekom
The Prekom family passion has always been cars, technology and aiming to do things that they like the most. This spark led to the start of production and renovation of steering and suspension car parts in 1978, and the second generation is now running the business. Over time they have focused on manufacturing and industrial renovation of aftermarket suspension and steering parts. After initially working across a wide variety of car brands, including steering parts for buses, transportation and construction vehicles, they have for the last two decades specialised in stock replacement steering and suspension parts for Porsche, Ferrari, Maserati and Lamborghini vehicles. Prekom are also OEM to several Porsche parts. Information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.
Choosing the Right Fit for Your Porsche
Where Prekom parts are listed for Porsche, use the supplied model coverage and OE references on the product pages to confirm suitability. Pay close attention to details that commonly affect fitment such as model year, body variant, steering layout, side/position, and any notes about bushes, joints, or mounting style.
- Typical reasons people replace these parts include wear in steering and suspension components, restoring precise handling and safety, and choosing stock replacement options that match original characteristics.
- Common symptoms before replacement can include knocking over bumps, vague steering, wandering, uneven tyre wear, vibration through the wheel, and clunks when turning or braking.
- Practical tips include planning for a professional wheel alignment after steering or suspension work, inspecting related bushes and joints at the same time, and replacing parts in axle pairs where sensible for balanced behaviour.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the diagnosis and parts choice grounded.
Steering Parts — Steering components from Prekom are used to restore precise control and feedback in Porsche models where listed. They are typically chosen when addressing play, knocking, or vague steering, and when you want stock replacement parts that work with the original system design.
Track Rods — Track rods (tie rods) connect the steering rack to the hubs; Prekom replacements, where available for Porsche, are used to remove play, improve alignment control, and bring back a direct steering feel during routine maintenance or front-end refresh work.
Suspension & Axle — In this area, Prekom suspension and axle parts for Porsche are aimed at bringing ride, stability and braking behaviour back to how it should be when original components have worn, with a focus on stock-style geometry and fitment.
Track Control Arms FRONT — Front track control arms from Prekom, where listed for Porsche, are selected to correct geometry, reduce unwanted movement and restore steering precision when original arms, bushes or ball joints have degraded.
Suspension Upgrades — Where Prekom components appear within suspension upgrade packages for Porsche, they are generally used to renew key wear items as part of a wider upgrade, helping keep geometry consistent while other performance parts are fitted.

Stock Spec Spring Plate Bushes
A true stock spec bushing replacement for spring plates.
Spring plate bush condition can be accessed by looking at the hole in the spring plate cover. It should be concentric around the spring plate. When the bushings deform, the cover becomes non-concentric around the spring plate and in extreme cases actually contacts the cover plate – metal-to-metal.
More than just bushings, this is a full kit that includes inner and outer bushings (4 pcs), adhesive, instructions, long bolts to press in the bushings, and abrasive cloth to prep the surface.
Rubber is the choice if you want to restore factory ride and performance in a zero-maintenance solution. Check our PolyBronze Bearings for a high-performance solution.
Also see our Bushings Removal Tool to simplify the removal of old bushings.
Notes – 1967 spring plate bushings changed mid-year
The following 1967 chassis numbers transitioned to the late style 1969-89 style bushes.
• 1967 911 from Chassis Number 307 325
• 1967 912 from Chassis Serial 354 938
• 1967 911 S from Chassis Serial 305101 A
All earlier 1967 chassis numbers use the early 1965-67 style bushes

This bushing installs directly in place of the factory part without modification.
This replacement bushing is especially useful during restoration, front-end maintenance, or when the original mount exhibits signs of wear - ensuring safe, predictable handling and preserving chassis integrity.
Worn or degraded support-frame bushings can lead to excessive play under load, compromising suspension geometry and causing unstable handling, uneven tyre wear, or unpredictable steering feedback. In addition, degraded rubber can transfer vibration and noise into the cabin, reducing comfort and potentially accelerating wear on other suspension or chassis components. Replacing with a correct-spec bushing restores firm, damped support - preserving handling precision, ride comfort, and the structural integrity of the front sub-frame.
When to replace. Consider replacing when:
• The original bushings are cracked, flattened, perished or visibly damaged
• There is clunking, looseness or unstable handling under braking, cornering, or uneven roads
• You are performing a front suspension, frame or chassis overhaul
• You are undertaking a restoration or recommissioning of a classic 911/912

Front Control Arm Front Bushing, Sport Hardness (Forward Position).
Upgrade your Porsche’s front suspension with this Front Control Arm Front Bushing – Sport Hardness.
Designed for Porsche 964 and 993 models, this bushing replaces the factory front mount of the lower control arm, providing a stiffer, more durable connection between the wishbone and subframe.
The sport hardness compound (approximately 25% stiffer than stock rubber) minimizes unwanted flex and maintains consistent alignment under load. The result is improved cornering stability, sharper steering response, and better feedback without significantly compromising ride comfort.

What This Product Does:
- The bushing is the interface between the control arm and the subframe / mounting point.
- It permits controlled movement (for suspension travel) while resisting unwanted motion so the wheel alignment remains stable.
- The firmer (sport) version deflects less under cornering, braking, or acceleration loads, helping maintain alignment geometry under load.
- By resisting deflection, it helps reduce unwanted movement in the front suspension, improving handling precision and steering feedback.
Symptoms Of A Worn / Failing Bushing:
- Vibration felt in the steering wheel, especially under certain loads or speeds (“shudderiness”)
- Looseness / play in the front suspension — less precise steering response
- Alignment changes under load — the front toe may drift during cornering or braking
- Clunking or knocking noises over bumps or from the front suspension
- Uneven or increased tire wear, especially on the front edges
- A degraded “feel” to the front end — less sharpness or a vague response in turns
Why The Sport Hardness Version Matters:
- Better control under load: Because this bushing is stiffer than stock, it deflects less in aggressive driving, helping maintain suspension geometry (camber / toe) more accurately in dynamic conditions.
- Sharper steering feel: Less compliance means more direct response, reducing mushiness in the front end.
- Reduced suspension movement / slop: Particularly helpful in performance, track, or spirited road use where loads are higher.
- Longer service life (in some cases): A harder compound may resist aging and fatigue better in high-stress conditions, though it may transmit slightly more noise, vibration compared to softer rubber.
- It still retains enough flexibility to absorb some road input, balancing performance with comfort.
