Jon, I beleive that the duck tail actually reduces drag beleive it or not, where as the Carrera and Turbo Tails reduce lift.
But as Jack Olsen pointed out, you need to be doing triple figures to have any real effect.
I beleive that the old Porsche advertisments used to say that it was an 'improver' as opposed to a 'spoiler'. They even quoted the downforce in lbs at certain speeds!.
maybe someone can elaborate on this?.
I am very interested in your experience with hill climbs as I wish to enter this in the future when I returnto the UK.
Have you raced at Gurston Down?
