Why Upgrade to 19-Inch Volk Racing Wheels?
Choosing 19-inch Volk Racing wheels is not merely an aesthetic decision; it is a performance-driven upgrade rooted in motorsport engineering. Volks, produced by Rays Engineering, are forged using a proprietary process that yields an exceptional strength-to-weight ratio. The reduction in unsprung mass directly improves suspension response, acceleration, and braking. This guide covers critical installation steps and provides data-backed insights into the real-world power and performance gains you can expect.
The Engineering Behind Volk Racing Wheels
Volk Racing wheels are forged from 6061-T6 aluminum alloy under immense pressure, creating a dense, grain-aligned structure. This forging process eliminates porosity and allows for thinner spokes and barrel walls without sacrificing structural integrity. The result is a wheel that can be up to 20–30% lighter than a comparable cast wheel. For a 19-inch diameter, typical weights range from 18 to 22 lbs per wheel depending on the model, whereas cast equivalents often exceed 27 lbs. This weight reduction is rotational mass, which requires significantly less energy to spin and stop, amplifying the effect beyond a simple static weight saving.
Installation Tips for 19-Inch Volk Racing Wheels
Proper installation ensures safety, optimal performance, and longevity of your wheels. The following steps detail the process from initial fitment check to final torque verification.
1. Verify Fitment Parameters
Before mounting any wheel, confirm that the 19-inch Volk Racing wheel matches your vehicle’s critical specifications. Even within the same diameter, hub bore, bolt pattern, offset, and backspacing can vary by model year and trim.
- Bolt pattern: Common patterns include 5×100, 5×112, 5×114.3, and 5×120. Use a bolt pattern gauge or measure center-to-center of adjacent studs.
- Offset (ET): Expressed in millimeters, offset determines how far the wheel sits inward or outward from the hub mounting surface. Incorrect offset can cause rubbing on the fender or suspension components. Volk Racing offsets typically range from +15 to +50 for 19-inch applications.
- Hub centricity: Most modern vehicles use hub-centric wheels where the center bore matches the hub diameter. If your Volk wheels have a larger bore (common with multi-fitment models), use hub-centric rings to prevent vibration.
- Brake clearance: 19-inch wheels provide generous clearance for big brake kits, but always test-fit the wheel over the caliper before final installation. Use a cardboard template or physically mount the wheel with only two lug nuts to check gap.
2. Acquire the Proper Hardware
Volk Racing wheels often use tapered or ball-seat lug nuts depending on the model. Do not reuse factory lug nuts if they are a different seat type. Additionally, because aftermarket wheels require a specific torque and thread engagement, we recommend using high-strength, heat-treated lug nuts or bolts that match the wheel’s seat profile.
- Lug nuts: Use closed-end or open-end as needed, with a 60-degree taper for most Volks, except for certain models (e.g., TE37SL) that require a special splice washer system.
- Wheel spacers: If offset adjustment is needed, use bolt-on hub-centric spacers, not slip-on spacers, to maintain proper load transfer and avoid stud shearing.
- Torque wrench: Critical. Calibrate it annually and never use a breaker bar for final torquing.
3. Prepare the Vehicle and Workspace
Work on a level, solid surface. Loosen the old lug nuts (or bolts) while the vehicle is on the ground. Raise the car using a jack at the manufacturer-recommended lift point, then secure it on jack stands. Never work under a car supported only by a jack. Remove the old wheel and inspect the hub face for rust, debris, or damaged studs. Clean the hub with a wire brush and apply a thin layer of anti-seize compound only to the hub center bore (not the studs) to prevent galvanic corrosion.
4. Mount the New Wheel and Torque in Stages
Place the Volk Racing wheel onto the hub. If using hub-centric rings, insert them first. Hand-thread the lug nuts in a star pattern to ensure the wheel seats evenly. Use a torque wrench to tighten in three stages: 30 ft-lb, 50 ft-lb, then final torque per manufacturer spec (typically 80–100 ft-lb depending on stud size and wheel material). Do not exceed the specified torque; overtightening can warp the rotor or strip threads.
5. Post-Installation Checks
After torquing, lower the vehicle and bounce the suspension several times to settle the wheel bearings. Then re-check the torque on all lug nuts within the first 25–50 miles. After 100 miles, verify torque again. Listen for unusual noises and feel for steering wheel vibration at highway speeds. If vibration occurs, re-balance the wheel and tire assembly or verify that the hub-centric rings are properly seated.
6. Special Considerations for 19-Inch Diameter
Larger diameter wheels like 19 inches increase the moment of inertia. This means the lug nuts must be tightened evenly to avoid warping the wheel. Additionally, tire selection becomes more critical: choose a tire with a load index matching or exceeding the original equipment, and an aspect ratio that maintains the overall diameter within 3% of stock to prevent speedometer error and ABS anomalies.
Real-World Performance Gains from Upgrading to Volk Racing Wheels
While accurate power gains are often exaggerated in the aftermarket community, reducing wheel weight delivers measurable improvements in acceleration, braking, and handling. Here is a breakdown based on empirical testing and physics.
Reduction in Rotational Inertia
Rotational inertia scales with the square of the radius. For a 19-inch wheel, a 1-pound reduction at the rim is equivalent to at least a 2–3 pound reduction in static weight for acceleration purposes. Swapping a 28-lb cast wheel for a 20-lb forged Volk can drop approximately 32 lbs of rotational mass across all four corners. This translates to:
- 0–60 mph improvement: Approximately 0.1–0.2 seconds on a typical 300–400 hp vehicle.
- Quarter-mile time: A reduction of 0.1–0.3 seconds depending on traction and gearing.
- Braking distance: Shorter stopping distances, as the brakes have less rotating mass to decelerate.
Impact on Acceleration and Handling
Because less energy is required to spin the wheels, your engine can deliver more torque to the pavement in response to throttle inputs. This is particularly noticeable when accelerating from a corner exit or during quick lane changes. The reduced unsprung weight allows the suspension to follow road contours more accurately, improving grip and transient response. Many drivers report a more "planted" feel and reduced understeer in tight corners.
Heat Dissipation and Brake Performance
Volk Racing wheels are designed with open spoke patterns that promote airflow across the brake rotor. Better heat transfer reduces brake fade during aggressive driving. Additionally, the lower mass of the wheel means less heat generated from braking. In repeated high-speed stops, this can maintain consistent pad friction and reduce pedal travel.
Quantified Power Gains: A Case Study
On a dynamometer, the effect of lighter wheels is not measured as increased wheel horsepower directly, but as reduced driveline loss due to lower parasitic drag. In a test performed by a tuning shop with a 2019 BMW M4 (425 hp), swapping 20-inch heavy factory wheels (29 lbs each) for 19-inch Volk TE37 Ultra (18.5 lbs each) showed a 4–6 lb-ft increase in torque at the wheels under acceleration from a standing start, and a consistent 0.15-second reduction in 60–100 mph times. This improvement is equivalent to adding approximately 10–15 whp in terms of effective acceleration, though the peak power number did not change.
Long-Term Benefits: Fuel Economy and Tire Wear
Lower rotational mass also improves fuel economy slightly—typically 1–3% in city driving—because the engine does not have to work as hard to accelerate the vehicle. Furthermore, reduced unsprung weight decreases harshness transmitted to the tires, potentially extending tread life if alignment and inflation are maintained.
Conclusion
Adapting 19-inch Volk Racing wheels is a technical project that rewards careful planning and precision. By verifying fitment, using proper hardware, and following a staged torque procedure, you can safely unlock the performance advantages these wheels offer. Real-world gains include quicker acceleration, sharper handling, and improved braking, all resulting from the reduction in unsprung and rotational mass. While the power gain is not an increase in engine output, the effective acceleration improvement is tangible and significant—especially for drivers who value response and lap times.

When combined with a proper alignment and performance tires, your Volk Racing wheels will transform your driving experience.
