Product Information
Product Information
Rear control arm bushing set.  Price is for 6 bushes. 
Designed to replace Porsche’s factory silent bloc in rear suspension link arms. Engineered for road use and built to OEM tolerances, this is a direct-fit, stock-spec solution for various Porsche 993.

Fits:
Porsche 993 1995-98 Stock Hardness

Replaces the rubber bushing on each of the rear 993 lower wishbone, camber control arm, and KT control arm. Each arm has 1 rubber bushing, for a total of 6 bushings per kit… enough to do one car.

Stock-hardness – Restores performance and ride quality to original.

Sport-Hardness – Similar to the 993 RS bushing, sport hardness rubber is about 25% firmer. Deflects less under cornering loads and thereby maintains alignment more precisely.

Features & Benefits
  • OEM-equivalent rubber compound for a compliant, comfortable ride 
  • Designed and manufactured in the EU with strict quality control 
  • Backed by Prekom’s 2-year warranty  
  • Straightforward installation; no modifications needed on stock link arms

If you're serious about how your 993, 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. Rubber Boots not included but available separately.

Prevent Alignment Settings From Slipping

Losing on the track is bad enough, but losing the alignment on the track is even worse. Prevent your eccentric adjuster bolts from slipping under heavy cornering loads with our Eccentric Adjuster Locking Kit.

Complete kit includes four lockout plates. Two plates are used to lock the rear toe adjusters and two plates to lock the camber settings.

Retain convenience and functionality of the eccentric adjuster. The original functionality of the adjuster is completely preserved. The plate can be set in any position.

Retain full range of the adjuster. These lockout plates do not limit adjustment range in any way, maximum toe and negative camber can be achieved with these plates in place.

Works with OEM fixed length arms and our adjustable length control arms as well.The unique design features a slotted hole that counters the slot provided for the adjuster. The plate can be moved up and down to reach any camber or toe setting desirable.

The Locking plates function by increasing the friction that holds the factory eccentric adjusters in place. These plates are guaranteed to prevent any adjuster slip even under aggressive driving conditions.

About Control Arms Rear

Rear Control Arms (Coffin Arms) – Stability, Alignment and Rear-End Control

Rear control arms, commonly referred to as coffin arms, are critical suspension components responsible for controlling rear wheel alignment, stability and handling balance. Mounted between the rear hub and chassis, these arms manage camber and toe movement as the suspension compresses and extends, directly affecting traction, tyre wear and overall vehicle confidence.

At Design911, we supply OE replacement and performance rear coffin arms from trusted suspension manufacturers. Whether you are addressing worn factory components or upgrading for fast-road and track use, rear control arms play a vital role in maintaining predictable handling and restoring proper suspension geometry.

What Do Rear Control Arms (Coffin Arms) Do?

Rear control arms locate the rear wheels and guide their movement through suspension travel. Their primary functions include:

  • Maintaining correct rear wheel camber and toe
  • Providing rear-end stability under acceleration and cornering
  • Supporting predictable handling balance
  • Reducing unwanted suspension flex

Because the rear suspension governs traction and stability, worn or flexing coffin arms can significantly affect handling feel and tyre life.

Why Upgrade or Replace Rear Coffin Arms?

Upgrading or replacing rear control arms offers:

  • Restored rear suspension geometry and alignment accuracy
  • Improved traction and stability during cornering
  • Reduced uneven tyre wear
  • Better feedback and control during spirited driving

Performance rear control arms may feature stronger materials, uprated bushes or adjustable geometry, allowing fine-tuning of rear suspension setup for performance driving or track use.

When Should You Replace Rear Control Arms?

Rear coffin arms should be replaced or upgraded when:

  • Suspension bushes are cracked, worn or noisy
  • Rear alignment cannot be set correctly
  • Handling feels unstable or unpredictable
  • Uneven rear tyre wear is present
  • Performing a suspension refresh or performance upgrade

Replacing worn rear control arms helps restore factory handling characteristics and improves overall driving confidence.

At Design911, our rear control arms meet OE or performance standards, supporting both professional servicing and enthusiast upgrades.
