More Grip, Better Tire Contact Patch
Updates the rear suspension camber curve to meet the needs of modern, wide, low-profile radial tires. The result is superior grip in turns, superior grip in straight-line braking, reduced tire wear. Excellent for both street and track.
✔ Improved contact patch in turns
✔ Improved contact patch for straight-line braking
✔ Go street-to-track with one camber setting
✔ Reduced tire wear
✔ Reduced camber thrust/rolling resistance
ASP Makes The Tire Gain Camber Faster.
As the suspension compresses in turns, countering the effects of body roll and matching the needs of modern radial tires. The tire remains square with the road surface and the contact patch is improved. Grip increases.
With the ASP '69-'89 911s can now achieve modern suspension performance.
How Does It Work?
The 911 suspension was designed in the early 1960s for narrow, high-profile, bias ply tires of the day. '60s bias ply tires did not need or like a lot of negative camber.
Fast forward 50+ years to 2013 – tire technology has progressed – we run wide, low-profile, radial tires. Modern tires need a lot of negative camber to grip well. No surprise, the 911 suspension designed nearly 50 years ago doesn't match the needs of modern tires!
All modern Porsches are designed with aggressive camber curves matching radial tires needs beginning with the 1990 911(964) and continuing through the current models. The ASP updates the early 911 suspension to similarly perform with modern radial tires.
The core problem is illustrated by the stock blue 911 pictured, the tires follow the lean of the car in the turn – causing poor contact as the tires roll over onto the outside edge. The rate of camber gain is too slow, grip suffers.
Easy To Setup Toe And Camber Independantly
Replaces the troublesome stock eccentric adjusters with simple double-adjusters.
ASP allows adjustment with vehicle weight resting on the tires making it easy to read a camber / toe gauge while turning the adjusters. Quick changes can be made trackside even if a camber gauge is not available.
✔ Upper and lower double-adjusters
✔ Rotate same direction to set toe
✔ Rotate opposite direction to set static camber
Replaces stock '69-'89 spring plate blade and spring plate cover. Bolt on – no welding required, works with torsion bars or coilovers. Use with any standard size bushing – not included – PolyBronze recommended. Requires the splined hub portion from a set of factory adjustable spring plates or the QuickChange Spring Plate splined hub. Download instructions for more information.
Note – Some images show the ASP pictured with optionally available QuickChange Splined Hub and PolyBronze Bearings. Trailing arm is not included and is shown for reference only.

Change Torsion Bars and Adjust Ride Height
QuickChange spring plates make fast-work of torsion bar re-indexing and replacement. Screw-type adjuster makes corner balancing and ride height adjustment a breeze. Pairs the high quality of the factory design with ease of servicing.
• 5 minute torsion bar changes
• Fast and easy ride-height adjustment
• Accepts standard bushings
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.

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.
Two Height Settings
Choose stock height or 1 inch raise for anti-squat geometry (requires matching raise of trailing ar
