Extreme Dimensions® 107421 - R-1 Style Rear Diffuser (Unpainted)

Extreme Dimensions Urethane body panels give you the best combination of style and durability. Each panel is individually crafted to give your car unsurpassed aerodynamics. Every Urethane component is flexible, making it easier to install than other more rigid materials like fiberglass.

Another benefit of Urethane over fiberglass is durability. If you should inadvertently hit a curb or bottom a fiberglass panel on a driveway, you'd most likely be looking at a cracked or broken part requiring expensive repairs or even replacement. Not so with Urethane. Its flexibility makes it durable, so it bends instead of cracking or breaking.

If you want parts that not only make your car look the best right out of the body shop, but also for years to come, get Extreme Dimensions Urethane body parts.
