The Ampliform is Konig's mesh-inspired wheel design, built with flow forming technology to deliver a lighter, stronger wheel than a traditional cast design. It's built for drivers who want an aggressive, motorsport-styled look across a wide range of sizes and bolt patterns. Flow forming applies pressure to the wheel's inner barrel while it spins on a lathe, after the barrel has already been cast. That combination of heat, pressure, and rotation compresses the aluminum's grain structure, producing a barrel that is lighter and stronger than the same section cast alone, with greater resistance to shock and impact. Construction Flow formed aluminum construction Mesh-inspired design available across 17 to 19 inch diameters in 5x100, 5x112, and 5x120 bolt patterns Finished in Gloss Bronze or Dark Metallic Graphite What's Included One Konig Ampliform wheel in the size, bolt pattern, and finish selected Each size, bolt pattern, and finish combination is sold as a single wheel. Product Specifications Konig rates every size below to a maximum load of 1,521 lbs. Centerbore is determined by bolt pattern, so confirm it matches your vehicle's hub or plan to use a hub-centric ring.

Order four for a full set. What does flow formed mean?The wheel's inner barrel is pressed and stretched under heat while spinning on a lathe after casting, compressing the aluminum for a lighter, stronger barrel than a straight cast wheel. Does the centerbore change between sizes?Yes. Centerbore is tied to bolt pattern: 73.1mm on the 5x100 versions, 66.6mm on the 5x112 versions, and 72.6mm on the 5x120 versions. Check the table above for your specific part number. Do I need hub-centric rings?Only if your vehicle's hub diameter is smaller than the centerbore listed for your size and bolt pattern above. Are lug nuts or bolts included?No. This listing is for the wheel only. Not sure which size, bolt pattern, or offset fits your car?Share your vehicle and tire details and contact your BMP Tuning rep to confirm before you order.
