If you're serious about how your 996, 997, 986 Boxster, 987 Boxster, 987 Cayman, 991, 981 Boxster and 981 Cayman handles, you should upgrade the factory tie rods with an adjustable bump steer kit. There is one major drawback to the factory tie rods, bump steer. Bump steer results from a tie rod that is angled from the steering rack to the spindle. An angled tie rod end will have a larger horizontal travel distance than the rest of the suspension, compared to a level link. Rennline's adjustable bump steer kits solve this problem. Manufactured from 6061 aluminum and feature a turnbuckle design that allow each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. A number of spacers are also included and can be added or removed accordingly to get a level tie rod for your vehicles specific ride height. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car’s alignment settings, ensuring predictable cornering under all conditions.

Note: 2 kits required per car. Rubber Boots not included but available separately.

Upgrade your stock front swaybar with this simple bolt in replacement for the factory drop links. These drop link are cnc machined billet 6061 aluminum and angled to fit 997TT/ 996C4 / 997TT /997C4 w/factory struts or Bilstein PSS9 and PSS10's. Left & right hand threaded rodends allow for simple length adjustment to eliminate swaybar preload.

Correctly sized, precision, Teflon-lined rod-ends for smooth and quiet operation, long life, and high reliability. No wear and rattling problems, like those seen with other designs, due to undersized or low quality rod ends. Eliminates the factory compliant plastic drop link bushings that deflect under loading and quickly wear out. High misalignment, steel spacers allow for superior bind free operation and corrosion resistance. Precisely connects the stock or adjustable swaybar to the front strut assembly for improved feedback and swaybar response. Overall length is adjustable to accommodate either stock or adjustable swaybar requirements.

Sealed Monoball Cartridges - Front and Rear - Most Porsche owners today, especially those of us who take our cars to the track, have equipped our cars with tires much wider and stickier than stock, which allows higher g-forces to be achieved in cornering and braking. During that type of hard driving, rubber suspension bushings are compressed and flexed by the extreme loads being put on them, defeating your car's finely tuned alignment settings, thereby reducing your braking and cornering potential. Mono balls are a downside-free improvement; because they eliminate four important sources of suspension slop without making your car's ride harsher. Your Porsche will handle and brake with greater precision, predictability, and feedback to the driver. Rennline mono balls are equipped with FK Motorsports bearings, cadmium-plated and Sealed to prevent premature wear due to moisture or dirt contamination, ensuring long track or street life.

If you're serious about how your 996, 997, Cayman, or Boxster handles, you should upgrade the rear suspension with adjustable control arm links. There are two major drawbacks to the factory links:
1) You can't lower your car and maintain proper suspension geometry. The factory links create too much toe-in, which cannot be adjusted out, creating handling problems and excessive tire wear.
2) The factory links have rubber bushings, which make handling imprecise, especially in performance driving when suspension loads are highest.

Rennline adjustable control arm links solve both these problems. Manufactured from 6061 aluminum and feature a turnbuckle design that allows each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car's alignment settings, ensuring predictable cornering under all conditions. Rennline arms come with all required bolts and machined bushings to get the job done.

Fits:
Porsche 996 C4 / C4S / Turbo / Turbo S
Porsche 997 C4 / C4S

PRODUCT DESCRIPTION
These RWD conversion spindles will allow you to remove your front axles, differential, and driveshaft allowing you to convert your AWD 996 or 997 to RWD. This conversion will increase the performance of your 911 by removing nearly 100 lbs. of weight while simultaneously reducing the amount of drivetrain loss. This will improve the driving dynamics to handle more akin to the infamous 911 GT3 & GT2. Due to our spindles having integrated ABS reluctor rings like the OEM c/v shafts, no ABS or PASM warning lights will ruin your fun and all electrical systems will retain full functionality. Each spindle is machined from durable carbon steel and coated with yellow zinc to prevent corrosion, ensuring our spindles will last a lifetime. This modification is completely reversible and does not require permanently modifying any parts on your car.

The RSS Adjustable Rear Link Kit is the proper way to correct the rear suspension geometry of lowered 996 and 997 models which greatly improves handling and feedback. The additional negative camber in the rear can prematurely wear out rear tires as the factory eccentric bolts do not offer enough adjustment to properly re-align the car to desired specifications.

About Suspension Upgrades

Porsche Suspension Upgrades & Components

Your Porsche’s suspension is the key to its handling, comfort, and safety. Upgrading or maintaining your suspension system not only restores factory performance but also unlocks sharper cornering, improved ride quality, and greater driver confidence.

At Design911, we supply a complete range of suspension upgrade parts for Porsche, including:

  • Anti-Roll Bars
  • Control Arms
  • Lowering Springs
  • Drop Links
  • Strut Mounts
  • Polyurethane Bushes
  • Engine / Gearbox Mounts

We stock world-renowned performance brands such as DesignTek, Bilstein, Ohlins, Koni, Powerflex, H&R, KW, and Nitron, trusted in both road and motorsport applications

Why Upgrade Your Suspension?

  • Improved Handling – reduce body roll, sharpen steering response, and corner with confidence
  • Better Ride Quality – balance comfort and control for road or track use
  • Increased Durability – high-quality components outlast standard rubber parts
  • Performance Customisation – tailor ride height, stiffness, and response to your driving style
  • Safety & Stability – maintain consistent contact with the road under all conditions

Key Suspension Components

Anti-Roll Bars (Sway Bars)
Reduce body roll during cornering, keeping your Porsche flatter and more stable. Perfect for spirited road driving or track use.

Lowering Springs
Improve handling and aesthetics by lowering your car’s centre of gravity. Can enhance steering precision while giving your Porsche a more aggressive stance.

Drop Links
Connect anti-roll bars to the suspension arms. Upgraded drop links ensure accurate movement transfer and eliminate play that can develop in worn components.

Strut Mounts
Provide the critical connection between the suspension strut and chassis. Replacing tired mounts restores steering accuracy and reduces knocking noises.

Polyurethane Bushes
A performance upgrade over standard rubber bushes. Poly bushes (such as Powerflex) offer increased durability, sharper response, and reduced flex under load.

Engine Mounts
Help stabilise the engine under acceleration, braking, and cornering. Upgraded mounts reduce drivetrain movement, improving handling feel and gear change precision.

Common Signs of Suspension Wear

  • Knocking or creaking noises over bumps
  • Excessive body roll or poor cornering stability
  • Uneven tyre wear
  • Steering feels vague or less responsive
  • Ride height appears uneven
  • Vibration or harshness through the chassis

Bilstein – legendary German dampers and coilovers for road and track
Ohlins – motorsport-grade suspension with advanced adjustability
Koni – durable, high-performance shock absorbers
Powerflex – market-leading polyurethane bushes
