My Challenge Rear Diffuser Now Installed

slimflem · 08-04-2010, 06:44 PM

visually looks good, but just an honest question about diffusers. What is the point? Does it really make a difference for normal daily driving and interstate driving? what are the benefits besides eye-candy? i'm not being a jerk, I honestly want to know. i have thought about doing this as well, but need to understand the benefits first.

Holy... that's awesome love all the mods- what did you do to the roof?

I like it but I would like it even more if there was another slat in the middle.

Looks good indeed!

I've seen the diffuser in person, fits like glove and excellent quality. Thumbs up to Challenge Engineering!
