18x5.0 D5 Drag Wheel 5x4.5 BC 2.125 BS

The 18x5.0 D5 Drag Wheel 5x4.5 BC 2.125 BS from Forgestar is purpose-built for dedicated drag racing and competition vehicles where every tenth of a second matters. Designed for serious bracket racers and street-legal drag enthusiasts, this wheel maximizes sidewall flex and reduces rotational mass during launch, delivering the lightweight performance that separates winners from the field. At 18.8 lbs per wheel, this is genuine competition-grade engineering—not a street compromise.

The D5 design combines a narrow 5.0-inch width with Forgestar's proven monoblock forging process, creating a rigid yet compliant structure that handles the violent acceleration and deceleration cycles inherent to drag racing. The 2.125-inch backspace positions the tire optimally within the wheel well, minimizing sidewall stress while maintaining clearance for large brake packages and suspension geometry tuning common in competitive builds. With a 5x4.5 bolt pattern, this wheel integrates seamlessly into Chevrolet (small-cap 4.5-inch patterns), Ford, and Mopar platforms that dominate drag racing classes from street-legal grudge racing to sanctioned NHRA competition.

Bracket racers and full-time drag competitors will appreciate the repeatability and durability of Forgestar's forged aluminum construction—there's zero flex between rounds, ensuring consistent tire contact patch and ET performance lap after lap. The minimal 18.8-lb weight reduces unsprung mass, lowering rotational inertia during tire spin-up and improving launch traction on prepped surfaces. Installation is straightforward on any vehicle with 5x4.5 lug spacing; verify backspace compatibility with your specific suspension and fender work before ordering to ensure proper clearance during compression and droop cycles under heavy acceleration.
