Richard, here's where I sheepishly admit that my main priorities (mistakenly) originally lay in the horsepower side of the car equation.....
I don't know the
CG height or location (and I have no idea what's involved in the measurement/calculation of same). I can only say that my motor seems to sit about two inches further back than the ERA 289FIA mounting location
Other than that accurate assessment (

), the car really is like any other plain old Cobra replica chassis in design. As such, if you have a "ballpark" CG height in your mind for the average Cobra it'd be pretty safe to use it.
The
weight is 2420lb
The
caliper piston sizes are:
Front - 1.75", 1.38", 1.38"
Rear - 1.75", 1.75"
Front and rear rotors are both 13" diameter - cross drilled, ventilated and slotted on the front, slotted and ventilated on the rear.
Richard, I'm embarrassed to ask for advice when I can't tell you a definitive answer required to accurately answer my question. In any case, if you think you have a pretty good idea of what bore size I'll need, I'd be happy to hear from you!
Thanks very much,
Craig
