Spring Plate

Spring plate PolyBronze bearings
For Porsche 911, 912, 930 1968-1989 Spring Plate SAW



PolyBronze bearings are superior to plastic bushing alternatives, here's why:

Suspension mounts are coarse sheet metal pressings. They tend to be out-of-round and have irregularities that deform ordinary polyurethane bushings, pinching and binding the friction surface. Polyurethane is "grippy" with an inherently high coefficient of friction and combined with pinching polyurethane bushings create a lot of friction. The result is a harsh ride and reduced tire adhesion.

PolyBronze have a rigid bronze bearing core that does not deform. The polyurethane jacket absorbs mount irregularities while the bronze inner bearing remains true, providing a free-moving machined-fit that rides on a precision race. Provided grease fittings make re-lubrication a breeze and a figure 8 groove keeps grease in place.

The combination delivers zero squeaks and friction-free suspension movement. Well suited to street or track, ride quality.

PolyBronze is a precision bronze bearing encased in a polyurethane jacket. The combination delivers a smooth-ride with the extreme performance of a metal bearing.

✔ No squeaks or binding
✔ Extremely smooth ride quality
✔ Easier to install than rubber bushings
✔ Integrated grease fittings and grooves

Note – 1967 spring plate bushings changed mid-year. The following '67 chassis numbers transitioned to the late style '69-'89 style bushes.

• '67 911 from Chassis Serial Number 307 325
• '67 912 from Chassis Serial Number 354 938
• '67 911 S from Chassis Serial Number 305 101 A

All earlier '67 chassis numbers use the early '65-'66 style bushes.

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.

Diagram Ref No 16

What This Product Does:

• Holding the torsion bar end and anchoring it to the chassis or suspension structure.
• Providing a mounting surface for the torsion bar to twist against, effectively managing the rear spring action (torsional stiffness).
• The adjustable aspect allows you to change preload, camber, or ride height for tuning the rear suspension setup to your desired performance balance (road or track)
  
• Helping maintain correct geometry as suspension moves, ensuring better tire contact, handling, and responsiveness.
  
  

Symptoms & Signs You May Need Replacement:

• Rust / corrosion / fatigue: The old plates may be rusty or weakened, especially in classic cars.
  
• Sagging or misalignment: Rear ride height may fall, or camber might drift under load.
  
• Uneven tire wear: Because geometry is off or not held firmly, the tires may wear more on one edge.
  
• Poor rear handling / unpredictable grip: The rear may feel loose under cornering or shift unpredictably under load.
  
• Difficulty setting or maintaining geometry: Without adjustability, it’s harder to dial in suspension tweaks, especially for track use or changed setups (wider tires, stiffer suspension, etc.).
  
  

Why This Upgrade Matters:
Factory spring plates offer limited adjustment. This RS-style sports version allows quick and accurate tuning of ride height, preload, and camber, giving sharper handling and better tire contact for both road and track.

Spring Plate Sports Quick Adjust Rear Set.
Upgrade the rear torsion-bar mounting of your Porsche 911 with this high-performance spring plate set. Designed for 1969-1986 911 models, this pair of indexed, quick-adjust plates replaces the original fixed units with a setup that allows ride-height, preload and corner-balance tuning. The “Sports” version features stiffer mounting bushings and precision manufacturing to reduce deflection and improve rear suspension stability under load.
Sold As A Set.

Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L

Diagram Ref No 16

What This Product Does:

• In torsion-bar rear suspension setups of early Porsches, the spring plate is the mounting point for the torsion bar end. It anchors the bar and defines ride height, preload and geometry of the rear axle.
• The “quick adjust” / indexing feature allows fast ride height or preload changes without major disassembly — enabling easier suspension setup or tuning.
  
• The “Sports” version also implies stiffer bushings or upgraded materials to reduce flex under load, improving rear-end stability and alignment retention during dynamic driving.

Symptoms & Signs You Might Need It:

• Rear ride height is incorrect or one side sits lower/higher than the other — the original plates may have settled, corroded or lost indexing.
  
• Rear suspension feels vague or loose in corners — the torsion-bar mount may be deflecting under load because the plate is worn or the fixings no longer rigid.
  
• Uneven tyre wear on the rear, indicative of changing geometry under load.
  
• You’ve modified the rear suspension (lowered ride height, stiffer springs, track use) and the original fixed spring plates limit your ability to set proper ride height or preload.
• The original plates are rusted, corroded or damaged — since many 911s from that era are several decades old, replacement can restore integrity.

Why This Upgrade Matters:

• The quick-adjust design gives greater flexibility to set the rear suspension correctly (preload, ride height, corner balance) — valuable in restoration, performance or track setups.
  
• Upgraded “Sports” bushings/plates reduce unwanted flex and movement, meaning the torsion bar mounting remains more stable, which improves handling precision, alignment retention and tyre life.
• For a classic 911 which may have been lowered or upgraded, the standard spring plates may no longer be optimal; installing this set helps the entire rear suspension perform as intended or better.
• It’s also a practical maintenance upgrade: replacing aged plates removes a common wear item and avoids downstream issues caused by degraded rear suspension mounts.

Setup is fast and easy

If you've ever re-indexed torsion bars to correct ride height, you can really appreciate the benefits of QuickChange. Used in combination with our QuickChange Torsion Bars and Polybronze bearings, this spring plate allows rapid replacement or re-indexing of torsion bars.

QuickChange Torsion Bar Changeout

QuickChange Torsion Bars can be extracted through the QuickChange Spring Plate without removing any bolts. Alignment settings are maintained. You don't even need to remove the wheel from the car. Changing torsion bars is a 5 minute per side operation!

Unlike other aftermarket spring plates, QuickChange Spring Plates bolt the plates together. This prevents the plates "halves" from sliding against each other and eliminates failures and metallic clicking noises common with competing products.

Can be used with any torsion bar and bushing that fits factory spring plates – not included – however QuickChange Torsion bars and PolyBronze Bearings are required to use torsion bar extraction features.

Kits for '69-'86 long wheel base cars include a screw type height adjuster. Kits for '65-'68 short wheel base cars use an eccentric bolt height adjuster for improved tire clearance.

To add QuickChange functionality to your existing set of '77-'86 factory adjustable spring plates or ASP, you can order the Splined Hub separately.

Splined Hub Kits

The Splined Hub Kit includes the small plate and adjuster hardware to mate with the large plate from your donor set of factory adjustable spring plates, or the ASP. Order one kit per car.

Porsche 930 Turbo
Porsche 912's with rear coil overs

Features & Quality
Our coilover-only spring plate system has the added features and thoughtful engineering you expect from Elephant Racing.
Rubber Seals

Rubber seals keep water and contaminate out of the oversized precision rod ends. Seals are critical to extend rod end life for both racers and street cars. Racers have the occasional "agricultural excursion", covering the suspension with grit and dirt that accelerates wear of unsealed rod ends. Street cars have occasional exposure to water when washing or in rain. Rubber seals are key to long life.
Build Quality

Skillful TIG welding and machined radius on the plate. Hard anodize burgundy aluminum parts are tough, attractive and look good on most any color car. Top quality materials throughout.

Hardened alloy steel blades and aircraft grade aluminum to handle even high HP turbos.

Precision, Oversize rod end – For long trouble-free performance.
Ease of adjustment

Drilled hole positively defines plate length ensuring proper thread engagement at double adjuster and rod end, preventing accidental over-extension possible with double-slotted designs.
