15 X 8 Steel Rim, Series 21, 4 On 130mm, 2 Backspacing

OVERVIEW

When you''re building a machine designed to conquer the dunes or navigate tight wooded trails, your wheel choice is the foundation of your entire suspension setup. The EMPI Series 21 Steel Rim is engineered specifically for the air-cooled enthusiast who demands rugged durability without sacrificing that classic off-road aesthetic. Measuring 15 inches in diameter with a massive 8-inch width, this wheel is designed to support high-flotation tires, providing the wide footprint necessary for maximum traction in soft sand or deep mud. The heavy-duty steel construction ensures that whether you''re airing down for the rocks or taking a hard landing off a jump, your rims will maintain their structural integrity far better than fragile aluminum alternatives. This is the workhorse of the VW off-road world, built to take the abuse of the trail and keep on rolling.

The defining characteristic of this particular Series 21 wheel is its aggressive 2-inch backspacing. By moving the mounting surface closer to the inside of the rim, the wheel is pushed significantly outward from the drum or disk, creating a much wider track that dramatically improves lateral stability and helps prevent rollovers during high-speed cornering. This "deep dish" look is the quintessential style for Baja Bugs and Manx-style dune buggies, giving your Volkswagen a mean, wide-shouldered stance that screams performance. These wheels are the gold standard for budget-conscious builders who refuse to compromise on strength or style. Whether you are building a woods buggy, a beach cruiser, or a full-blown desert racer, these steel rims provide the reliability you need when you are miles away from civilization.

FITMENT

This wheel features the standard late-model Volkswagen 4 on 130mm lug pattern. It is designed to fit a wide range of air-cooled applications, though body modifications are often required due to the aggressive width and backspacing.

• Volkswagen Beetle (Standard): 1968 through 1977 (Rear fitment only without flares).
• Volkswagen Super Beetle: 1971 through 1979 (Requires fender modifications).
• Volkswagen Karmann Ghia: 1967 through 1974 (Fits rear with wide fenders).
• Volkswagen Type 3 (Squareback, Fastback, Notchback): 1966 through 1973.
• Dune Buggies & Sand Rails: Any custom chassis utilizing 4-lug VW transaxles or spindles.
• Baja Bugs: Perfect for use with cut fenders and fiberglass wider-eye kits.

PRO TIPS

1. Mind Your Fender Clearances

Because this wheel has a very shallow 2-inch backspacing, it pushes the tire much further out than a stock "narrow" rim. If you are mounting these on a standard steel-bodied Beetle, they will stick out past the factory fenders by several inches. For a street-legal look and to prevent the tires from catching the fender lip under compression, we highly recommend using these in conjunction with wider fiberglass fenders or a complete Baja Bug conversion kit. Always cycle your suspension through its full travel to ensure the tire doesn''t contact the bodywork, which could lead to a dangerous blowout on the trail.

2. Use the Correct Lug Hardware

Never reuse your stock Volkswagen lug bolts with these heavy-duty steel wheels. Stock VW bolts typically feature a radius (ball) seat, whereas most aftermarket steel wheels like the EMPI Series 21 require a 60-degree taper (cone) seat lug nut or bolt. Using the wrong seat type will prevent the wheel from centering correctly on the drum and can lead to the lugs loosening or even snapping the studs. If you are running these on a buggy with a stud conversion, ensure you have at least 1/2-inch of thread engagement for maximum safety during high-stress off-road maneuvers.

3. Balancing and Tire Pressure

When mounting large off-road tires to an 8-inch wide steel rim, balancing becomes critical for any street driving. Steel wheels are inherently heavier than alloy, and the added rotating mass can cause significant vibration if not balanced correctly. We recommend "static" balancing for
