A trick some of the bike guys do is just before the take off, they pry open the discs a touch with a pry bar. Gets it done, but if you enclose your brakes inside a disc, another approach might be necessary.
Mark once mentioned machining the disc a few thousandths off center to push the pads out as you roll - a trick some sports racers embrace - but few capable of over 200 mph.
It all depends upon where you run and how fast you go.
I asked Joe Timney last year about running my Midget at Wilmington. I'm only running rear drums, and ran a best of 126 in 3 at Bonneville - it might hit 110 in the mile on pavement - he didn't think it would be a problem.
You'd likely be using much bigger brakes than I do, and they ran drums in NASCAR up until - what - the late 1960s when they were getting close to 190 mph in cars that weighed 3500 lbs.
In the end, you need to feel safe driving it.
