I recently bought a Venom spoiler to  :hayes: fascia scoop I installed into my GTS.  After buying my ACR and seeing that the mileage goes down quite a bit between 50 and 90 mpg I now think that the rear Spoiler will add too much downforce to the back of my car.  Assuming that the Viper came balanced already I think I need to add some downforce to the  nose to get my balance back.

At the SRT tech sessions they said that there is 200# of downforce needed at the back for every 100# added to the front.  The SRT engineers also said that the Canards add 100# to the nose.  Now I'm thinking that adding a pair of ACR similar canards should be enough to balance my car.

Any opinions?

Well you added about 75lbs to the front with the Roe and supporting mods, so the canards may or may not be needed to balance out the downforce from the wing.

Yes it works similar to a splitter because it allows air to go into the radiator instead of going under the car.  There's only about 3#  and that's offset by the piece of pvc you cut out of the nose so Tim mean that there was about 75# of downforce added.
