My FFR was built to be a "driver", not necessarily a racing machine. First and foremost, I built it because I simply love the curves of the body and the overall boner I get when I step in and just drive around. Having grown up around a Ford Fairlane station wagon and owning a 65' Mustang (4sp.4bbl 289) the FFR spoke to my youth and it's just the way I wanted to keep it... a 60's machine with some modern build, but true to it's root. This meant a total immersion of builder, driver, and mechanic. I have since had two close calls due to cold tires, spinning 45 deg. on one but another a good 270 deg. but luckily, no crashes. YES, I have learned huge respect (also, swapped out the Nitto drag radials... that had a little to do with it.) I've let two people drive my car. One is a certified racer and he didn't do anything more than drive it like a normal car but did note it's NOT race car by any standard (he's done Indy lites and lower class NASCAR and shifter carts.
The other was my nephew that I first took to a parking lot and had him run circles and a little right turn here and there to get a feel for brake, throttle and steering. Even then he's apprehensive (scared) and has only driven it across the lawn to his company's car show 2 times with me in it.
It's the only car where I am fully aware of who's around all clocks of my position on the road. Thankfully, there are no blind spots
After some 7 years and 25,000 miles, I'm can say I'm cautiously comfortable with this beast. And yes, I've seen the rookie crash of the tirespin in 2nd and immediate off-throttle car spin thereafter. Wasn't a pretty site but it was at least repairable and nobody got hurt... I'll leave it at that (no, it wasn't me.)
