Gain back ride quality and rear end stability with High Density Rear Spring Plate Bushings for your 911. Under prolonged use, especially when driven hard, the OEM bushings can break down allowing more slop in the rear suspension. If neglected long enough or driven under heavy load enough, these bushings will eventually deform allowing the spring plate to contact the cover plate. Replacing your factory bushings with our 25% stiffer units will allow full and smooth articulation of the spring plate, thus improving the ride quality and performance of the legendary rear end in your classic 911. Featuring a higher, "sport" durometer these rubber mounts are a great compromise between soft factory mounts and solid/spherical bearings often used to replace them.

The Porsche Washer for Camber Adjuster is a genuine OEM component designed to ensure precise suspension alignment. Used as part of the camber adjustment assembly, this washer acts as a spacer and load distributor, helping maintain secure and accurate positioning of the suspension arms.
Sold Each.

- Porsche 911 1965-1968 2.0L / 912 SWB (F)

- Porsche 928GTS 5.4L 1992-95
What This Product Does:
- As a washer used in a camber adjuster, its job is to act as a spacer or shim between the adjuster mechanism and adjacent components (arm, bracket, nut, etc.).
- Helps maintain the correct alignment spacing / preload so that camber adjustment geometry is precise and held firmly.
- Prevents metal-to-metal friction, distributes load, and ensures fasteners seat properly.
Signs / Symptoms Of Fault Or Need For Replacement:
- Camber adjustment doesn't stay stable — alignment drifts or slips.
- Unwanted play in suspension / control arm area near the adjuster.
- When removing or reinstalling camber adjuster, the original washer is worn, bent, or shows damage.
- Hard to achieve the correct alignment or shim stack due to missing or damaged spacer.
Why Replacement Matters:
- Ensures accurate alignment — camber settings rely on precise spacing, and a worn or missing washer can ruin alignment.
- Preserves hardware life — correct spacing reduces uneven stress or wear on adjuster bolts, bushings, or arms.
- Maintains safety and handling — camber out of spec can lead to poor tyre contact, excessive wear, or less stable cornering.
