EMPI Front Caster Shim Set - 4.00 Degrees - 6061 T-6 Aluminum (Pair)

Restore high-speed stability and steering precision to your lowered Volkswagen with the EMPI 4.00 Degree Front Caster Shim Set. When an air-cooled VW is lowered—especially with an adjustable front beam—the caster angle often becomes too "vertical," leading to "twitchy" steering, front-end wander, and poor cornering return.

These shims are precision-machined from 6061 T-6 Billet Aluminum to tilt the beam back, increasing positive caster. This adjustment improves "straight-line" tracking on the highway and ensures your steering wheel returns to center more effectively after a turn. By using a single 4-degree shim instead of stacking multiple thinner ones, you maintain a more secure, stable mounting surface for your front axle beam.

Key Features

• Precision Geometry: Provides exactly 4.00 degrees of caster adjustment to correct front-end geometry on significantly lowered vehicles.

   

• Premium Billet Material: CNC-machined from 6061 T-6 aluminum for high strength and resistance to compression.

   

• Improved Stability: Reduces front-end "hunting" and wander at high speeds, a common issue with lowered Beetles and Ghias.

   

• Alternative to Stacking: Eliminates the safety risks associated with stacking multiple thin shims on extreme-lowered setups.

   

• Sold as a Pair: Includes two shims—enough for one complete front axle beam installation.

Vehicle Fitment

Designed for all standard (non-Super Beetle) air-cooled Volkswagen front-axle beams, including both Ball-Joint and Link-Pin configurations.

Tech Tip: Adding caster shims increases the distance between the beam and the frame head. You may require Longer Front End Mounting Bolts to ensure proper thread engagement. Check your current bolt length before completing installation.
