Hubcentric Ring Set (4)
Up for auction is a set of 4 composite plastic hubcentric rings that will fit any 5-lug BMW made in the late 70's through at least the early 2000's. These hubcentric rings have an outside diameter of 74.1mm and an inside diameter of 72.56mm. The leading edge is tapered.
Why install hubcentric rings? It is best to install a wheel with a center bore (the hole in the middle) diameter that is the same as the hub diameter of the car. A tightly fitting hub/wheel interface will lessen the chance of annoying wheel vibrations. All the BMWs mentioned above have a hub diameter of 72.56mm. The OEM wheels installed on those cars had a matching center bore so the wheels were centered on the hubs perfectly. This provides a nice smooth ride that sells cars.
The problem is that some BMW enthusiasts want to install larger and newer wheels on their older cars. Many of the newer OEM wheels (from E38 and E39 cars) have a center bore diameter of 74.1mm. When installed on a car with a hub diameter of 72.56mm, the wheel may not be centered about the hub and there will be a chance of a wheel vibration at speed. The solution is the fill the gap between the two different diameters with a hubcentric ring.
Are these rings durable? These are high strength composite plastic that won't fuse to the hub or wheel as do alloy rings. When installed they will last for long time. Loose, they are somewhat fragile, so please use care when handling them.
What is included? Included are 4 hubcentric rings, one for each hub.
How do I install them? Installation is very simple. Just clean up the hubs, slide the rings on, and then install your "new" wheels. I recommend applying a dab of antiseize lube so prevent the wheel from adhering to the ring or hub itself.

CAR tech: who's to blame for your car's terrible fuel economy?
Mon, 12 Aug 2013In early 2013 Audi lost a case brought by the Advertising Standard Agency (ASA) because of ‘misleading’ fuel economy figures used in an advert, after a customer complained they couldn’t get anywhere near the 68mpg quoted. The court case once more exposes the yawning gap between officially sanctioned mpg figures and those experienced by owners. A recent study by the Independent Council on Clean Transportation (ICCT) looked at cars sold in the UK and Europe, and discovered the difference between official mpg figures and real-world driving had grown from 8% in 2001 to a barely believable 21% in 2011.
Audi A3 Sportback e-tron price and specs – costs £34,950
Mon, 28 Jul 2014Audi A3 Sportback e-tron (pictured) costs £34,950 If governments are going to base car taxation on Co2 emissions, then car makers are going to build cars that ‘game’ the official tests. A perfect example of which is the new Audi A3 Sportback e-tron plug-in hybrid. It’s expensive at £34,950 (although the government bribe for plug-ins does drop the price you pay to £29,950), but thanks to its ‘up to 31 miles’ range on battery power only it comes complete with official economy of 176.6 mpg and emissions of 37g/km.
