How much downforce is applied to rear of 930 with OE whaletail
Is it the same with my cabriolet with the roof down

Just a little something to get your minds going even quicker

Thanks for all of your help guys

I don't have it handy, but Paul Frere documents the various tails and their effects in his "Porsche 911 Story". Most factory tails provide lift reduction, although I believe the stock Turbo tail actually crosses the lift reduction line to provide a little downforce.

I saw a diagram a while ago.
If I remember correctly the 930 turbo and 964 turbo had a little bit of lift at high speed, not much though.
