Fitment Notes

• Bolt pattern: 4x100mm - confirm your vehicle's bolt pattern before ordering
• Hub bore: 73.1mm - hub-centric rings are recommended for vehicles with a smaller hub bore (e.g., Mazda MX-5 ND hub bore is 54.1mm and requires a hub-centric ring)
• Offset: +45mm - verify clearance with brakes, suspension, and fender wells for your specific application
• Clearance note: clears Wilwood big brake kits; does not clear optional Brembo calipers - confirm brake kit clearance for your specific setup
• Lug seat style: conical (tapered) - confirm lug nut type for your vehicle; lug nuts are not included
• Sold individually - one wheel per unit; a set of four requires four units

Features

• Flow Formed (Rotary Forged) construction - cast aluminum center spun under heat and pressure to stretch and strengthen the barrel, producing a wheel significantly lighter and stronger than traditional cast designs
• Weighs approximately 17.19 lbs. - meaningful unsprung weight reduction compared to OEM cast wheels, improving acceleration, braking, and steering response
• Six-spoke mesh-inspired split spoke design - each spoke splits at the face for a 12-spoke visual effect that balances motorsport aesthetics with brake cooling airflow
• Spoke profile promotes efficient airflow for improved brake cooling during track and spirited street use
• Generous brake caliper clearance - confirmed compatible with Wilwood BBK setups
• Gloss Bronze finish - warm, distinctive color that stands out against both light and dark paint
• Load rated at 1,543 lbs. per wheel (700 kg) - strong load rating for a flow-formed wheel in this size class
• Center cap with Konig logo included

Product Description

The Konig Ampliform in 17x8 with a +45mm offset is a flow-formed performance wheel built around the 4x100mm bolt pattern - making it a natural fit for sport compact and enthusiast platforms like the Mazda MX-5 Miata, Honda Civic, Mini Cooper, and BMW E30. Konig's Flow Forming Technology begins with a cast aluminum center and uses high-pressure rollers under heat to stretch and compress the barrel, producing a wheel that is substantially stronger and lighter than a conventional cast wheel. At approximately 17.19 lbs., the Ampliform delivers real unsprung weight savings that translate to sharper steering response, quicker acceleration, and improved braking feel - benefits especially noticeable on lightweight sport cars where every pound matters.

The six-spoke split design gives the Ampliform a motorsport-inspired mesh appearance that promotes brake cooling airflow to the rotor - an important detail for track days and spirited driving. The gloss bronze finish is a standout color choice that pairs well with a wide range of paint colors. The Ampliform's spoke geometry is confirmed to clear Wilwood big brake kits (a 3mm spacer may be needed for some Wilwood caliper kits), though it does not clear Brembo calipers - verify brake kit clearance before ordering. Hub-centric rings are required for vehicles with a hub bore smaller than 73.1mm, such as the MX-5 Miata. Lug nuts are not included.
