Konig UG85100364 Ultragram 15x8 4x100 +36mm Carbon Bronze Flow Formed Wheel

Vehicle Fitment

• Universal - 4x100mm bolt pattern, 73.1mm hub bore
• Compatible with many 4-lug vehicles including Honda Civic, Mazda Miata, Toyota Yaris, Nissan Versa, Hyundai Accent, Kia Rio, Mini Cooper, and more

Fitment Notes

• This is a universal 4x100mm wheel - verify bolt pattern, offset, hub bore, and clearance for your specific vehicle before purchase
• Hub-centric rings may be required for vehicles with a hub bore smaller than 73.1mm
• 15x8 +36mm offset may require fender modification or rolling on certain vehicles
• Tire size and suspension setup should be confirmed for proper clearance

Features

Product Description

The Konig Ultragram is the culmination of decades of motorsport engineering and real-world racing feedback. Built using flow forming technology, the Ultragram compresses aluminum molecules during manufacturing to produce a wheel that is significantly lighter and stronger than traditional cast alternatives. At just 12.51 lbs in the 15x8 configuration, this wheel delivers meaningful unsprung weight reduction that translates directly into improved acceleration, braking, and handling response.

The 7-spoke design is more than cosmetic - it was engineered using Finite Element Analysis to optimize the balance between weight savings and structural rigidity. A knurled bead seat is machined into the barrel to prevent tire slippage under high-torque loads, making the Ultragram equally suited for autocross, track days, time attack, and spirited street driving. The Carbon Bronze Metallic finish offers a refined, dark graphite appearance with subtle bronze undertones that sets this wheel apart from standard silver or black options.

This 15x8 size with a 4x100mm bolt pattern and +36mm offset is compatible with a wide range of popular 4-lug vehicles. Buyers should verify all specifications - including hub bore, offset clearance, and fender fitment - against their specific vehicle before purchasing. Hub-centric rings may be needed depending on the vehicle's factory hub bore. The wheel is sold individually and includes one center cap.
