can anyone comment if their is a difference between say venting out the side as per this pic and venting up over bonnet/hood r.e gt40 and some other racers? does it add downforce at the rear wing passing this "extra"air over the roof?
its also got a lot to do with the space that a mcpherson strut would take up in the boot of a sedan etc.
working on vw's all of them use a trailing arm style setup. id imagine its similar for other manufacturers?
