[Fot] gearbox legality

[Jack W. Drews]

I didn't realize until this thread started that some organizations 
allow other gearboxes if 'functionally equivalent". Same goes for 
brakes. Here are excerpts from SVRA's rules:

"Transmissions: Must be functionally equivalent to the unit provided 
by the manufacturer. Gear ratios are free with no increase in the 
number of forward speeds. Reverse must work."

The old TR gearbox with overdrive gives six speeds. Converting to 
Toyota or other would bring that back down to five.

Likewise on brakes, (too long to retype) the gist of it is that 
alternate rotors, drums, and calipers are allowed as long as current 
dimensions, materials, and pad area are maintained.

I really like those regs. Not all North American racing clubs agree. 
The only "advantage" these regs may give a competitor is in a 
reduction of maintenance cost and time. Everybody who has tried to 
keep Triumph transmissions intact for more than a couple of years, or 
anyone who has tried to make the new stainless brake pistons and new 
seals actually work, will appreciate what I mean.
