Don't feel bad mine isn't a perfect fit either but you cant tell unless you get down on your knees.
Have you thought about using a washer or a shim to "level out" the ground parallel issue you perceive?
Took it to cars and coffee today and everyone liked the CF diffuser, not a single person told me , " oh the drivers side is lower than the passenger side " and honestly I still can't see it so not sure what needs to "fixed" if it isn't broken. Sent from my Nexus 6P using Tapatalk
Or you could add a wee bit more air in the left rear tire if that would make yourself feel better! First world problems.
azzurribaggio - I was kidding about the driver's side being lower. The camera was tilted. It's fine. Move on. LMAO
