Simply put are they functional...Do they do anything but give a different appearance?

 

Looks mainly, Might do something well over the 100 MPH Mark.
1 thing I did notice was I get more dirt on the back of the car since installing the GT500 rear valance (similar to the Roush), so on that note is does change the air flow under the car some.

 

So there's more dirt on the valence?

 

All the way up the whole back of the car, probably would not even notice it except I have the White OTT Stripes on the car. And this is a mainly driving in the rain problem.

 

Anyone with the splitters or different rear valence notice any air noise or anything?

 

i have the gt500, no noise change.

not sure about the splitter having functionality

 

The side splitters match the style of the Roush front splitter and I doubt they interfere or add anything to the car other than styling. The side splitters should match the new street Boss front splitter. I hope to be able to confirm this in about three months.

 

So will I just in different way...if it's not to long I'll add the CS front valence with that splitter. I'm sure u can't wait to get your but I just want to see it

 

That's why I mentioned it, the CS valance is the same as on the Boss. The street Boss splitter should be available by early Spring.

 

I have the GT500 rear and Roush side splitters. Didn't notice any change in wind noise or aero. One thing about the GT500 rear is that it has accommodations for larger exhaust tip sizes (stock GT500 tips are 4"). I believe the Roush has the same.

 

Kool cause i just bought the roush off road exhaust and rear valence

 

Their install instructions are great for the rear valence. I used them for my GT500 one without any problems.

 

Have the Roush side splitters sitting in the garage, still in the box, as I didn't have the time to intall them yet. I guess I need to get some 3M adhesive promoter as well before installing, at least that's what the instructions are calling for.

Any other tips on the install of the side splitters?

 

I used some isopropyl rubbing alcohol! The instructions say to start in the front and work your way back but before you do that slip the side splitter threw the slit in the mud guard thing on your rocker molding by your rear tire(it takes alittle effort) then move to the front line up the splitter with the lines on your rocker molding and work your way back! When you get under there you will see what I mean! If you don't slip it threw the new side splitter doesn't sit right! PM me if you still unsure and i'll take picture of mine and send it to you!!!

 

The adhesive promoter works really well, I'd suggest using it.

I'm not totally sure what Chip is referring to, but you want to test fit it on the car with the clips removed and see if it sits. The main focus is the front edge, where the OEM skirt is molded differently than the rest of the piece, and the Roush splitter is made to mate to that.

I did mine on a set of ramps, and I used a right angle drill to get under the car. Saved a lot of time. Make sure to wrap the drill bit with tape so you don't pierce too far through the skirt when drilling the additional holes.

 

CDC side splitter and Boss valance and home made front splitter. Oh yes made the rear side splitter too.

 

Can you post some pics of the rear?

 

What spoiler is that?

 

Front "spoiler" lower valance is the CS/Boss part, splitter I made myself. I am going to make it bigger soon.

Rear valance is the GT500 part it is due for an update too.

 

Oh.. .I meant the wing spoiler... I kinda want one...
