Show original supplier description
The DevSport Rear Diffuser offers an aerodynamic upgrade for the 2002-2006 Acura RSX (DC5), designed as a seamless 1-piece unit. Constructed from durable aluminum composite, the top sections are 1/4" thick, providing significant strength and minimizing distortion, while the fins and side sections utilize 1/8" thick material for a balanced and robust design. The diffuser undergoes professional CNC machining to ensure precision and comes with pre-drilled mounting holes. A UV coating is applied for added protection against the elements, and the unit features a smooth satin black finish. The diffuser comes with all necessary hardware, including stainless black zinc hardware and black aluminum L-brackets, along with a DevSport badge. It is designed to fit stock bumpers for the 2002-2004 and 2005-2006 models, and can be fitted to a rear lip with minimal modifications.
