Easy Mach 1 Styling. If you're a fan of the 03-04 Mach 1 Mustang's front end styling, you can easily bring some of that Mach 1 profile to your regular 199-2004 Mustang by outfitting it with a SpeedForm Mach 1 Chin Spoiler. Replicating the design and appearance of that 03-04 Mach 1, the SpeedForm Mach 1 Chin Spoiler will deliver that same lowered and aggressive look to any New Edge Mustang. Rugged Urethane Construction. This Mach 1 Chin Spoiler styled replica from SpeedForm is built out of injection molded urethane. This is a great material to use for a part like a chin spoiler, as it remains slightly malleable when cured and is considerably less prone to cracking or chipping as compared to a plastic of fiberglass spoiler. The spoiler arrives unpainted and can be left as is to contrast with your factory color, or you can get it painted to match at a local body shop. Quick 30 Minute Install. Transforming the front end of your own 1999-2004 Mustang into something that is more akin to the ever popular 03-04 Mach 1 is pretty easily done with SpeedForm Mach 1 Chin Spoiler. Mounting the Mach 1 spoiler requires drilling several holes into the bottom of your factory bumper and then securing it in place with the supplied nuts and bolts. Overall, the process will take approximately 30 minutes and is something that any average mechanic can tackle.
