Where to go for hub specs?

[tr8todd]

These are my three options. http://www.wilwood.com/Hubs/HubList2.aspx?subname=&minorname=&bc=&bearset=A4&dimm=    The TR8 uses A4 and A1 bearings.  The common upgrade is to drill out the stock hub to accept an A2 bearing and then put a sleeve over the spindle to make up the difference in the inner race.  The bearing spacing(measurement M) on the wedge needs to be around 2.3", so the bearing pocket will need to be machined a little deeper for the bearing to ride on the spindle properly and not hang over.  I'm leaning towards the A body hub designed for vented rotors and a set of 12.19"X.81" vented rotors.  You can get those hubs with a 5X4.5 wheel bolt pattern that will match the Ford 8.8 rear end.  One of my TR8s has Rover SD1 struts and hubs.  Those hubs use A6 and A2 bearings, so finding a hub for that car will be much easier.  There are a ton of American cars that used those bearings.
