wiley:
I've read every word of the rules, it seems that I can use any solid rear axle, hubs, shafts, discs, drums, calipers, etc. The only limitation is the brakes mus stay either inboard or outboard. What does that mean?
Also, the rules do not specifically say I can swap from drums to discs. Is this allowed?
Outboard brakes are the most common. Outboard means the disks or drums are located with the wheel mounting hub and hub carrier and are un-sprung (ie: carried by the suspension). In board brakes are most common on independant suspensions and have the disks or drums mounted with the differential (one on each side) on the chassis and are therefore, sprung. The CV axles (or half shafts) run from the brake disk/drum out to the hub and hub carrier which is the unsprung portion of the suspension.
For a more simple illustration, consider a Miata as having "outboard" rear brakes. If they were "inboard" they would be mounted between the inner CV joint and the differential.
The E-Type Jag used inboard rear brakes.
Also, when the rules specifies you can use "any disk or drum" that assumes if you have drums, you can use a disk in its place. It does say "any disk".
