j's Rear Diffuser!
 

has anyone modify the diffuser on ap2? cause i know its for ap1 and i talk to the body shop person and they say they probably can do it...do ya think it could work to fit on ap2 rear bumper?

Nope, tried it...won't work unless you do a bit of trimming and new brackets.

I dont think it would be too smart of an idea to hack up a 1k dollar diffuser. just get the apr its a whole lot cheaper too
