GA Tech Motorsports

I plan on attending GA Tech in fall 2016, assuming I get accepted. How does their formula SAE team work? Do you just apply and join or do they recruit based on academics and ability/knowledge of auto type stuff. Also, I want to join wreck racing as well to help me gain more knowledge about the mechanics of cars. Apparently they will take anyone regardless of knowledge. The question is should I do both or would it be too time consuming? I would think that both clubs meet after classes at night. I really want to join both but I think formula SAE would look better on my resume.
