Been doing a lot of research on what's legal in E-Prod with SCCA and having a hard time figuring out what's allowed for rear wing aero. I saw a post from back in 2020 that suggested they're allowed but can't find any info on this in the rules that matches what was posted. It basically said they're okay if stock or were available as an option on the car. Anyone have a concrete citation on this in the newest rule book?
