A need for the GD Chassis

All I can say is it really completes the rear end for me. It looks great and it's easy to fit. Depending on your exhaust you will need to trim it. I have a Tomei Expreme Ti and it does clash. If you don't trim enough you'll get a horrible vibration noise as you come back through the revs so defintely give the exhaust at least 1/2 inch clearance.

So much easier to order it here, than from the dealer. I did have to trim it a bit to make sure it didnt hit my aftermarket exhaust. Looks great!

I admit I bought this mostly for looks, but I got the added benefit of a stiffer rear end with the Cusco rear subframe brace. Pretty good quality and fit is dead on.

Once i got the Cusco sub-Frame bar and brackets install, this thing took seconds to install. It just complete the back end. Love it! Thanks RSD !!
