Some of the best footbrake racers I know have had the same car for years, some over 30 years. They don't go faster, if it's 11.50 then it's 11.50 for years. They and their car have become one. A bad light for them is .020, but a .005 is not uncommon at all, yes footbraking. A change to the car would be a learning curve. These guys are worse than a root canal to put out.
