034Motorsport ZTF Wheels are fully forged, designed with ultimate performance in mind. ZTF Wheels are forged with 10,000 tons of pressure to produce a wheel that is incredibly strong, providing all of the performance attributes needed in a track focused wheel while also being practical for the street. Close inspection reveals scalloping of the spokes, giving the wheel rigidity while also keeping weight to a minimum. This design was chosen for its motorsports heritage and track-worthy strength. Each wheel features traction improving-bead seat knurling, a thicker inner rim flange for durability and strength, and machined accents for good looks. ZTF wheels are designed specifically for each application to provide the best appearance, optimal tire selection, and proper fitment with most popular aftermarket big brake kits. In addition, all ZTF wheels are durability tested according to DOT/SAE and JWL/VIA standards to ensure safety. ZTF Wheels are sold with a lifetime structural warranty against defects.

Specialized Sizing
Some of our wheel sizing may seem unconventional at first. For example, questions frequently arise regarding the 9.3 inch wide wheel. The answer is simple. The ZTF wheel line is unique compared to other wheels offered in the segment in that they are designed for precise, model-specific fitment to maximize tire size while ensuring adequate clearance to the fenders and suspension components. Since these wheels are fully customized by the 034Motorsport engineering team, the optimal width from a performance and fitment standpoint can be chosen. In some cases that still results in the conventional half-inch sizing scale. But for other cars where conventional half-inch increments are a compromise, non-standard widths can be designed, such as the 9.3 inch and 11.2 inch wide ZTF wheels. Rest assured that ZTF Forged Wheels for your specific vehicle will fit perfectly without any guessing games or modifications to fenders or suspension components.

ZTF Forged Wheel Features:

Knurled Bead Seat:
All ZTF Wheels utilize a gear-cut knurled bead seat that helps the tire hold onto the rim more securely, reducing slip and giving you better traction when driving hard.

Strengthed Inner Rim Flange:
This highlights how we shave off unnecessary material but reinforce critical areas. In this example, the inner rim gets added forged mass to help prevent bending from impacts.

Perfect Fitment:
Because these wheels are application-specific, we dial in the proper performance sizing and visual fit for each vehicle. The result is a wheel that performs at a high level and enhances the car’s appearance. 

Large Brake Capable:
ZTF Wheels are built to clear major aftermarket big-brake kits, starting right from the design phase. We keep the aggressive concavity and styling you want while using a raised rim barrel to make space for larger rotors and calipers.

Improved Spoke Rigidity:
ZTF Wheels incorporate structural enhancements, like the rigid spoke tracer, to boost strength and durability while keeping weight low. Increased stiffness helps the wheel resist bending under high loads, giving you more consistent handling and greater confidence behind the wheel.

Weight Savings:
Every wheel is carefully engineered to remove excess material while keeping critical areas strong for maximum safety and reliability. Each design is analyzed using FEA software and rigorously tested in both the lab and real-world driving conditions.
