You you will see swiftmotorsports as well as Altec Show-N-Go plate. Also some pics of front bumper removed to let you know some issues to overcome. According to the videos I've seen the Altec is quieter and cheaper at summitracing.com. Good luck and let me know how it turns out. I am in the market as well as soon as I receive my first ticket.
