Specifically engineered for \"slammed\" or ultra-lowered air-cooled Volkswagens, these shims are the most aggressive single-shim solution available. When you lower a VW front end significantly, the beam pivots forward, losing the positive caster required for stable handling — causing bump steer, front-end wandering at highway speeds, and a steering wheel that refuses to return to center.\u003c\/p\u003e\n\u003cp\u003eBy installing these 5.25-degree shims, you tilt the entire axle beam back, restoring necessary positive caster. This significantly improves straight-line tracking and driver confidence at cruising speeds. Machined from high-strength \u003cb\u003e6061 T-6 billet aluminum\u003c\/b\u003e, these shims provide a solid, singular mounting surface that is far safer and more stable than stacking multiple thinner shims.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eVehicle Fitment\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003eFits all standard (non-Super Beetle) air-cooled VW front axle beams, both ball-joint and link-pin:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eVW Type 1 Beetle (Standard):\u003c\/b\u003e 1946–1977 (except Super Beetle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVW Karmann Ghia:\u003c\/b\u003e 1956–1974\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVW Type 2 (Bus\/Transporter):\u003c\/b\u003e 1950–1967 (split-window models)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eVW Type 3 (Notchback, Fastback, Squareback):\u003c\/b\u003e 1961–1973\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDune Buggy \/ Sand Rail:\u003c\/b\u003e Standard VW axle beams\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cb\u003eWhy Choose EMPI?\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003eEMPI machines these shims from 6061 T-6 billet aluminum for a solid, non-compressible mounting surface — a safer, more stable alternative to stacking multiple thin plates.\u003c\/p\u003e\n\u003ch3\u003e\u003cb\u003eKey Features \u0026amp; Benefits\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eExtreme Adjustment:\u003c\/b\u003e Provides 5.25 degrees of caster — ideal for narrowed and adjustable beams or extreme drops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBillet Aluminum Construction:\u003c\/b\u003e CNC-machined from 6061 T-6 aluminum to prevent compression or shifting under suspension load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHigh-Speed Stability:\u003c\/b\u003e Eliminates the twitchy feeling of lowered front ends by re-establishing correct suspension rake.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSafety First:\u003c\/b\u003e A single-shim design eliminates the risks of shim walk or bolt loosening caused by stacking thin plates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSold as a Pair:\u003c\/b\u003e Two precision-matched shims for one complete front axle beam.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cb\u003eTechnical Specifications\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eCaster adjustment:\u003c\/b\u003e 5.25 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial:\u003c\/b\u003e 6061 T-6 billet aluminum (CNC-machined)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFits:\u003c\/b\u003e Standard (non-Super Beetle) ball-joint and link-pin front beams\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSold as:\u003c\/b\u003e Pair (one front axle beam)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e EMPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003ePart Number:\u003c\/b\u003e 22-3020-0\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cb\u003eFrequently Asked Questions\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eWill these fit a Super Beetle?\u003c\/b\u003e No — they are for standard (non-Super Beetle) front axle beams.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHow many come in a set?\u003c\/b\u003e A pair — enough for one complete front axle beam.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eWho is the 5.25° shim for?\u003c\/b\u003e It is the most aggressive single-shim option, ideal for narrowed\/adjustable beams or extreme drops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cb\u003eInstallation\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eTech Tip:\u003c\/b\u003e Because 5.25 degrees adds significant thickness between the beam and the frame head, \u003cb\u003eLonger Front End Mounting Bolts are mandatory\u003c\/b\u003e for a safe installation.
