does the rear wing ACTUALLY provide any benefit?

[rallyingrob]

..........or is it just for style points?

no seriously.......does anyone have anything in their collection of reading material that says the wing provides benefit?(ie: downforce or improved stability above a certain speed or.......?)

what im wondering is if i should ditch it in favour of the weight loss or keep it...it DOES give about 20lbs of downforce at the rear !! LMAO!!

when built, i wont be seeing speeds over 130 mph, and if i do its only for a few seconds(unless i rally in quebec where they seem to use gravel roads 4 lanes wide!!)

to paraphrase the clash..........should it stay or should it go now?!?

lol
