There was lots of nitrous, plenty of weight saving and relocation strategies, two right side ss leaf springs (iirc), efi, transmission upgrades and as mentioned, a crop of better than average drivers.
Initially, there was no spray-they did use two right springs (extra half leaf, IIRC). Trans was an 833 in an ancient (70's) Direct Connection aluminum case, with slant six (3.09) gears.
I believe an aluminum 8 3/4 chunk and torsen diff was part of later build as well.
Had a Mickey Thompson magnesium centersection for a while...ran the last two One Laps with a piece from a Nevada junkyard. 2.94 gears-originally ran the stock cone Sure Grip, new diff might be a Torsen. (E-berg really likes them.) The old M/T piece was about the only trick part on the whole car.
Rick has said more than once that the secret of the car's success was how light it was.
