You'd better just have some serious supports holding that cantilevered load on the car (according to NHRA rules, it would need twenty 5/8" diameter bolts...I think...it's two 5/8" bolts per 50 lbs., right?)
Nope, it's only two ½" bolts per 100 lbs, so he only needed 10 bolts or so IIRC the guy's first name was Blair. Does anyone else on here remember that car?

I see that only 500 lbs can be removable, but the balance can be bolted on and have the nuts welded to the bolts. Not that I would really consider it, but I have provision in my chassis for 200 lbs of removable ballast, plus using a factory rear Vega hatch (which added around 60 lbs IIRC). I remember adding it all on at a race to see if I could get to the 2500 lbs limit (at the time) of S/ST.
