Matt,
Thanks for the reply. I've been considering making a front undertray but having a premade one that would bolt on, even with a general level of fit, would be great. I'll keep an eye out for updates on performance and get in touch with you.
To level my air dam, I used a NASCAR urethane air dam rub strip. It is slightly adjustable, and I don't ahve to worry about knocking the paint off the bottom of the air dam. The gloss black also looks nice against the orange paint.
