Ahhhh, C4's. Rattle traps.... did you know that when they made the C5, they made the dash with 1500 less pieces just in the dash?

Rather than doing this why don't you start by turning the black rubber bump stops on the bottom of the rear hatch. Turning them will adjust them in or out, and you can do this to tighten the fit of the hatch so it wont rattle. Requires fingers and about 2 minutes. Try backing them out a half turn and then drive the car. If it still makes noise try another half turn.

Same thing goes for the front hood if it is out of alignment against the fender trim.

 

Doesn't surprise me, I think I had 1500 screws alone in my dash...Helped a friend once replace a heater core which required that the top dash pad come off...I didn't think we'd ever get that puzzle put back together again

 

As a bodyshop guy, I can only say you can't turn more than a turn or two before you start pushing the liftgate out where you can physically see it doesn't line up with the quarters.

But then again, I'm kinda ****.

Ornge Crush, just how did you get the 221 whp and 250 wtq? I'm going to be getting a JCW soon but want a little more street power. Thanks.

 

So many things to learn,so little time to learn them.

 

The 3 things I would suggest is....

a)RMW tune
b)CAI
c)catback exhaust

I've also got a larger intercooler, boost tubes.

The car starts off in the 2000 rpm range and stays at no less than 240wtq all the way to 6300.

HTH's,

Mark

Or you could lube the crap out of it with white grease.
