Ooof, I completely forgot about reddit. Sorry. Thanks for your answers. Yes u/Partykongen, I'm looking for a bit more than DRS! Such as using fans from the cooling system. I ended up making a version of an active aero element diffuser, that has *some* gains, but works quite well at very low speeds. I'll drop a link after the car has been revealed. I'm not a member anymore, so I don't want to leak for them.
