Where to start when designing an F1 chassis?

Where should one begin to design an Formula One car chassis after the safety cell? I have a basic safety cell 3d drawing complete following the FIA Technical Regulations for 2010. Suggestions?

Welcome to f1technical, nice to see new members!
Could you upload some pictures
If you want I have some 3D boxes (front and rear wing and diffuser) that shows allowed bodywork in these areas
I am using these boxes to control my car legality
Keep it up!!!

This is just the safety cell according to the FIA Rules for 2010 with no aerodynamic features w/ the headrest (i don't know the proper name for that).

I think the safety cell also includes the fuel tank. Or at least, the fuel tank should be within the safety cell if that makes more sense. Therefore your tub needs to extend further rearwards. The rear face of the new bit is the surface to which the drive train is then mounted.

Yes I know I just haven't designed the roll bar yet, that's why there isn't a fuel tank area behind the driver area.

without thinking outof the box ,Neweys v-shape of the tubis not possible...it is of course another question if the idea itself is that important.

Added some curvature to the chassis and headrest
This should give me a start on the roll structure

The fuel tank and rollbar/engine air intake is part of the tub, so can also the cooling air inlets. The engine is bolted directly on the back of the tub. The gearbox carries the rear suspention and the front suspension is attached to the tub. Cooling ducts and radiators are attached to the sides of the tub.
In front of the tub is the nosecone/front crashbox where the front wing is attached. On the gearbox the rear crashbox is attached. Under the tub is then ballast attached, then there is the floor section and the plank.
The rear bodywork is composed of the engine cover, and then there is the rear wing attached to the rear crashbox.

as you can see the structure to hold the confor foam is not part of the tub ,its only bonded panels .
Is your tub buck already at the permitted maximum width towards the engine interface/bulkhead?this will determine how long your tub will have to be to accomodate the required tank size..you may check with Nick Wirth....
tub design has to consider manufacturing feasibility as well ..is your plan to have top and bottom halves bonded together?
what about the required bulkheads some of them can be integrated .
avery interesting part will be how to mate the engine to the tub..How much does
an aluminium engine expand from room temp to working temp?the Carbon tub is unlikely to grow..

and this of course...with the hint at RedBulls R&D into flexi parts....
