These bolts are suitable for radius seated Porsche, and some VW alloy wheels and are a great way to replace rusty old bolts, instantly uplifting the look of your vehicles wheels.
Whether your wheels are radius seating depends on the manufacturer and is something you must check before purchase. Almost all aftermarket wheels are tapered, but standard wheels can vary. For example all BMW's come as standard with tapered bolts, all Mercedes come as standard with radius bolts, and most Porsche come with radius. It is important you get the seating correct to ensure that your car is safe.
