Konig HG08514258 Hypergram 18x10.5 5x114.3 +25 Race Bronze Flow Formed Wheel

Vehicle Fitment

• Universal fitment for vehicles with a 5x114.3 (5x4.5") bolt pattern and a hub bore of 73.1mm or smaller (with the use of hub-centric rings where applicable). Compatible with sport compact, sport sedan, and enthusiast vehicles across Honda, Acura, Subaru, Nissan, Mitsubishi, Ford, Mazda, Hyundai, Kia, Toyota, Lexus, and other platforms using the 5x114.3 bolt pattern.
• The 18x10.5 size at +25mm offset is primarily recommended for rear axle use in staggered fitment setups - pairing a narrower front wheel (typically 18x8.5 or 18x9.5) with this wider rear wheel. Confirm full staggered fitment compatibility with your vehicle before purchasing.
• Use Konig's fitment guide at konigwheels.com to confirm this specific size (18x10.5, +25mm offset) is appropriate for your vehicle and intended axle position before purchasing.

Fitment Notes

• Offset: +25mm (ET25). A lower positive offset at 10.5" width pushes the wheel face further outward toward the fender. Verify that +25mm is within the acceptable offset range for your vehicle's rear suspension, fender arch, and body configuration. Lowered vehicles and wider-body builds may accommodate this fitment more readily than stock-height applications.
• Width: 10.5". Confirm that 10.5" width does not cause tire-to-suspension, tire-to-fender, or tire-to-body contact at your desired ride height and through the full range of suspension travel. Wide rear fitments typically require verification of inner fender liner clearance and suspension component clearance at full compression and steering lock.
• Hub bore: 73.1mm. If your vehicle's hub bore is smaller than 73.1mm, this wheel will not fit. If your vehicle's hub bore is larger than 73.1mm, hub-centric rings are required to properly center the wheel and prevent vibration. Confirm hub bore before ordering.
• Backspacing: 6.73". Verify backspacing clears rear suspension components, including trailing arms, control arms, and any rear brake calipers, particularly on lowered vehicles or with aftermarket brake upgrades.
• Load rating: 1,521 lbs per wheel. Verify this meets or exceeds the per-wheel load requirement for your vehicle on the rear axle.
• Exposed lug design - confirm your vehicle's lug nuts are compatible with the wheel's lug seat type (typically conical/tapered seat for aftermarket wheels). Incorrect lug nuts can damage the wheel seat and create a safety hazard.
• Sold individually - one wheel per order. A staggered setup typically requires one or two rear wheels of this size alongside a narrower front wheel.

Features

• Flow Form construction - Konig's manufacturing process begins with a cast aluminum wheel center, then applies high-pressure hydraulic rollers to the barrel under heat, stretching and compressing the aluminum to the final barrel width and shape. This refines the aluminum grain structure in the barrel, producing a wheel that is significantly lighter and stronger than a traditional gravity-cast design, with greater elongation and shock resistance properties, without the cost of full forging
• 19.06 lb weight at 18x10.5 - the Flow Form process's primary benefit is demonstrated directly in this figure: achieving 19 lbs in a 10.5"-wide 18" wheel is a result of the thinner, denser barrel walls only achievable through Flow Forming versus casting, which would require thicker walls and produce a meaningfully heavier wheel at this size
• 12-spoke motorsport design - the Hypergram's 12 thin spokes are spaced to maximize open area behind the spoke face for big brake kit airflow and caliper clearance, while the spoke count and geometry maintain structural rigidity under the torsional and impact loads of performance driving. The thin spoke profile reduces visual mass without reducing structural cross-section in the load-bearing direction
• Big brake kit clearance - the open 12-spoke design was specifically engineered to clear a wide range of aftermarket brake calipers and rotors. Always verify brake clearance with your specific caliper, rotor, and pad combination before finalizing the purchase - clearance varies by offset, vehicle, and brake kit dimensions
• Race Bronze finish - Konig's Race Bronze is a warm, matte-tinted metallic bronze that pairs well with a wide range of vehicle colors and maintains a clean, motorsport-oriented aesthetic; the matte quality of the finish reduces glare and is more forgiving of minor surface contact marks than a high-gloss finish in track and aggressive street use
• One-piece construction - center and barrel are a single integrated unit with no welds, fasteners, or bonding interfaces
• Non-directional design - can be mounted in any orientation and swapped between left and right sides without rotation restriction
• Engraved lip branding - Konig engraves model and brand identification into the outer lip for permanent, track-proof identification

Product Description

The Konig HG08514258 is the Hypergram in 18x10.5, 5x114.3, +25mm offset, Race Bronze finish. It is a one-piece Flow Formed aluminum wheel weighing 19.06 lbs, rated at 1,521 lbs load capacity, and sold individually. The 18x10.5 size at +25mm is primarily recommended for rear axle use in staggered fitment setups. Confirm vehicle fitment, axle position, offset, hub bore, and lug seat compatibility before ordering.

The Hypergram is Konig's flagship Flow Form performance wheel and one of the most recognized autocross and track-day wheels in the sport compact segment. At 18x10.5, this is the widest size in the Hypergram lineup - designed for staggered rear fitment on RWD and AWD platforms where maximum rear tire width is desired for traction and handling balance. The Flow Form process's structural benefit is clearly demonstrated at this size: achieving 19.06 lbs in a 10.5"-wide, 18" wheel requires the denser, thinner barrel walls that Flow Forming produces by compressing and refining the aluminum grain structure in the barrel - a weight that would be unachievable with conventional gravity casting at equivalent structural integrity.

The 12-spoke design provides an open spoke face with substantial caliper clearance behind each spoke for aftermarket brake kit compatibility - a deliberate engineering choice rather than an aesthetic one, giving the Hypergram its motorsport utility alongside its motorsport appearance. Always verify brake clearance with your specific caliper and rotor dimensions before purchasing. The Race Bronze finish is Konig's matte-tinted metallic bronze, available here alongside Matte Black, Metallic Carbon Gray with Machined Lip, and Matte Grey in this size. Lug nuts and hub-centric rings are sold separately.
