Re: Help Me, Wheel ?
Bore is your Hub bore on your hubs that you mount the wheel to, if that makes sense. 66.56 is the crossfire bore so your wheels need to have a 66.56 bore to mount hubcentric on your hub, so that you don't get any shaking in the steeringwheel. If you don't get the 66.56 bore you have to get hub rings that are the bore of your new wheels and then decrease or increase to the crossfires bore. And on the ADR's you need new shorter lugs because the stock ones are to long on the back wheels. I still need to order these for my wheels I am rolling on so rusty ones the tire shop gave me for free. The treaded part of the bolt (think it is called the shank?) needs to be less than one inch. Or you can use spacers.
Got this off a website: Hub centric rings are manufactured so that when they are installed on a vehicle, the wheels are located directly off of the centre flange of the brake drum or rotor. This is done to insure that the outer beads of the wheel are concentric with the wheel bearings. The result is a much truer, better balanced tire/wheel assembly. This is very important with modern high tech suspension systems.
