9-Spoke Flow-Formed Hyper Chrome Wheel Built for Big-Brake Clearance and Track-Ready Fitment
The Konig CT7510035C Countergram is a 15x7.5 flow-formed aluminum wheel in a 4x100 bolt pattern with a +35mm offset, 73.1mm hub bore, and 1,100-pound per-wheel load rating. The CT7510035C is sold as a single wheel. The Countergram uses flow-forming technology that applies hydraulic pressure to the inner barrel post-casting, producing a lighter and structurally stronger barrel than conventional cast methods. Konig designed the CT7510035C face-forward to maximize caliper clearance, providing adequate room for factory brakes and many aftermarket big brake kits commonly used in club racing and autocross. The hyper chrome center with mirror-machined lip is a two-tone finish that contrasts the polished spoke face against the deep-cut machined lip. Konig backs the CT7510035C with a lifetime structural warranty and a one-year finish warranty to the original purchaser.
Key Features
- Flow-Formed Construction: The CT7510035C barrel is produced by applying hydraulic pressure to the cast aluminum while spinning, creating a work-hardened inner barrel that is lighter and stronger than a standard cast barrel without the cost of a forged wheel
- Maximized Brake Caliper Clearance: Konig pushed the CT7510035C spoke face outward to create the greatest possible clearance between the wheel face and the brake caliper, accommodating factory brake hardware and most common aftermarket big brake kits up to 11 inches in rotor diameter on Mazda Miata platforms
- Hyper Chrome with Mirror Machined Lip: The CT7510035C features a hyper chrome spoke center paired with a mirror-polished machined lip for a high-contrast two-tone finish that complements both factory and aero-modified body panels
- 73.1mm Hub Bore: The CT7510035C uses a 73.1mm center bore matching Honda Civic, Acura Integra, and Mazda Miata hub diameters for hub-centric fitment on most common 4x100 platforms
- 1,100-Pound Load Rating: Each CT7510035C is rated for 1,100 pounds of static load, appropriate for lightweight sports and compact vehicle platforms
- Lifetime Structural Warranty: Konig provides lifetime structural coverage and a one-year finish warranty to the original purchaser through an authorized dealer with proof of purchase

Frequently Asked Questions
What is the Konig CT7510035C?The CT7510035C is the Konig Countergram wheel in 15x7.5 with a 4x100 bolt pattern, +35mm offset, 73.1mm hub bore, and hyper chrome center with mirror-machined lip finish. It is a single flow-formed aluminum wheel sold individually, rated for 1,100 lbs load, and backed by a lifetime structural warranty from Konig.
Is the CT7510035C sold as a single wheel or a set of four?The CT7510035C is sold as a single wheel. A full set of four requires ordering four units. Always verify center cap quantity with your order if your vehicle needs new center caps.
What is flow-forming and how does it benefit the CT7510035C?Flow-forming applies hydraulic pressure rollers to the inner barrel of the wheel while it spins after casting. This work-hardens the barrel material, increasing tensile strength and reducing weight compared to a standard cast barrel. The result is a wheel that approaches forged-barrel performance at cast-wheel pricing.
What is the hub bore on the CT7510035C and do I need hub-centric rings?The CT7510035C has a 73.1mm hub bore. This matches the hub diameter on Mazda Miata, Honda Civic (through 2000), Acura Integra (through 2001), and most Volkswagen Mk4 platforms. If your vehicle's hub diameter is smaller than 73.1mm, hub-centric rings are required for proper hub-centric installation and vibration-free operation.
Does the CT7510035C clear big brake kits?Yes. Konig designed the Countergram face-forward to maximize caliper clearance. On Mazda Miata applications, the CT7510035C clears all factory brakes, the StopTech 11-inch BBK, and the Goodwin Racing V5 11.75-inch BBK. A 3mm wheel spacer is required for the Wilwood 11-inch BBK. For other platforms, verify caliper clearance with your specific brake kit dimensions before purchasing.
What is the offset and backspace of the CT7510035C?The CT7510035C has a +35mm offset and 5.63-inch backspace. On a 15x7.5 wheel, ET35 places the hub face 35mm outboard of the wheel centerline, providing a moderate flush stance appropriate for most stock suspension configurations on 4x100 platforms.
What warranty does the CT7510035C carry?Konig provides a lifetime structural warranty against defects in materials and workmanship under normal use conditions, and a one-year finish warranty, both to the original purchaser. Warranty claims are processed through an authorized Konig dealer with proof of purchase.
Can the CT7510035C be used for autocross or track days?Yes. The CT7510035C is specifically designed with motorsport input from Konig's racing teams, and the face-forward spoke design is optimized for brake caliper clearance to accommodate big brake kits used in club racing and autocross. Verify that your specific competition rules permit 15x7.5 wheels and confirm tire sizing is within your class limits before competing.
Installation Instructions
- Confirm the CT7510035C fitment by verifying your vehicle's bolt pattern (4x100), hub bore, required offset range, and available tire clearance before mounting
- Mount the CT7510035C on a calibrated wheel balancer using the center bore for hub-centric mounting. Do not balance using lug-centric methods only
- Install hub-centric rings between the CT7510035C 73.1mm bore and your vehicle's hub if your hub diameter is less than 73.1mm
- Mount your chosen tire onto the CT7510035C. Common sizes for this fitment include 195/50R15 and 205/50R15 on most 4x100 platforms
- Torque lug nuts to your vehicle manufacturer's specification using a calibrated torque wrench. Do not use an impact wrench to final-torque aluminum wheels
- Re-torque lug nuts after the first 25-50 miles of driving following installation
- Clean the CT7510035C finish with pH-neutral soap and water only. Avoid acid-based wheel cleaners that can damage the hyper chrome and machined lip finish
