It’s ironic with a lightweight, high-hp car, isn’t it? I spent a great deal of time sweating blood to make my Beck Lister as light as possible when I was building it. She ended up at 1,976 pounds with a half-tank of gas so I was happy with that. In multiple track days the best lap I ever ran was with a 240-pound passenger, LOL. Don’t know if that’s a reflection of my need to cross-weight the car, if the extra weight helped the tires get up to temp, or if I just drive faster when I’m trying to impress.

Regarding aero, when I was tracking my Lister a lot I didn’t want to drill a bunch of holes in the body. I ended up mounting an APR wing to the roll bar (my bar extends the width of the car unlike a typical Cobra single-hoop design, so it was easy to do), making a splitter out of some high-impact material, fabbing a defuser from sheet metal, and then adapting some generic canards. The splitter and defuser bolt on but they’re both on the underside of the body where you’d never see the holes. The only visible holes are for the canards, and they’re pretty tiny. My “aero package” was all seat-of-the-pants but the car got faster afterwards, whether that was a reflection of aero benefits or just my increased confidence in it.
