Five Star Fabricating Spoiler Bracket

Five Star Fabricating Spoiler Brackets: Precision Hardware Built for the Track

When it comes to race car aerodynamics, the spoiler blade gets most of the attention — but it's the bracket that does the real work. Without a properly engineered mounting solution, even the finest polycarbonate spoiler blade can flex, shift, or fail under the aerodynamic loads generated at speed. Five Star Fabricating has understood this relationship since the company's founding in 1978, and their line of spoiler brackets reflects decades of race-proven development.

Built from the Ground Up for Short Track Racing

Five Star Race Car Bodies, a division of Five Star Fabricating, Inc., was formed in the late 1970s in Twin Lakes, Wisconsin, beginning as a direct response to the need for innovative sheet metal products in the stock car racing industry. That grassroots origin has never left the company's DNA — every bracket is designed with the real-world demands of short track competition in mind.

Five Star's spoiler sets feature a two-piece polycarbonate blade paired with a newly redesigned two-piece aluminum bracket, available unpainted or in a black powder-coated finish. The aluminum construction keeps weight low without sacrificing the rigidity needed to hold a spoiler blade firmly in place lap after lap.

Adjustability Where It Matters

Five Star spoiler bracket systems are designed to make rear bumper cover and deck lid height adjustable, fitting all current ABC and Late Model Stock Car (LMSC) bodies, while supporting the rear bumper cover and allowing easy adjustment of rear spoiler height. That adjustability is critical for teams dialing in rear downforce across different track configurations — a small change in spoiler angle can meaningfully shift the aero balance of the entire car.

Five Star's hardware provides everything needed for a precise, secure spoiler installation, including the hardware to mount the polycarbonate spoiler blade to the bracket and the bracket to the bumper cover. For teams looking for a complete solution, Five Star also offers a 76-piece polycarbonate spoiler mounting kit containing machined aluminum inner and outer washers, flat head socket screws, and locknuts — lightweight, yet heavy duty for a secure installation.

Engineering Standards That Come From Motorsports

Five Star bodies and components are engineered using a combination of advanced composites and high-impact thermoformed plastics, delivering durability, aerodynamic performance, and weight reduction. These same material philosophies carry through to their bracket hardware — all Five Star products are proudly engineered and manufactured in Twin Lakes, Wisconsin.

For Five Star, high quality means repeatable fit, flawless finishes, failure-free assembly, and no product recalls. For a crew chief bolting on a spoiler bracket in the pits before a feature race, that reliability is everything. Whether you're running a local weekly show or a regional touring series, Five Star Fabricating's spoiler brackets give you a mounting foundation as serious as the rest of your build.
