what is zero keel and V keel?
I found this very confusing at first. When you try to look up a keel, you find sailing stuff obviously. But of course over the years I found wiki.
Before the noses of the cars were so high off the ground, the front suspension was mounted to the chassis, but in high nose f1 cars there is no place to mount the lower suspension arms so they are flat.
The teams have adjusted over the years where to mount these wishbones.
Zero Keel - all the suspension bits are mounted to the body, and point down towards the track, ala Mclaren. This is the best for unobstructed airflow under the car, but makes the suspension geometry more complex.
The rest are here... I don't think you want me typing oput the whole Wiki for you, as the original is devoid of spelling errors. I've explained the McLaren as there is no zero keel entry, for obvious reasons. I make plenty
The Vkeel is considered to be a good middle ground between zero and single and dual. Each kind can be made to work. A V, Zero, and Single, have all won a championship in recent times.http://en.wikipedia.org/wiki/Suspension_keel
