I'm looking to upgrade my inner speakers and am not sure what sizes the front, back, and rear are. I went to a car audio shop and they told that they don't have any spec on the 08 yet.
I also was wandering if Mugen front grill and air spoiler will fit on the 08.

 

I have an 08 also, and I can't find anything different, so I doubt if the speakers and grill are.

 

I agree with that.
