i've got some stuff to fit to the skyline


Large rear wing
Cannars - or dive boards (?)
Large splitter to poke out the front and flat floor under the engine.

Its a start but I dont have the budget to go all the way with it.

The GTR is RWD most of the time with feck all weight at the back (diff/shafts/fuel).

I'll dig out pics of the carbon whorage

angles are very important... for example if i fit the cannards at too steep an angle of attack they'll just cause too much drag with air stalling at/on them.

Cannards



Splitter - I need to cut/fit etc




nice and big enough for flat bottoming under the engine

big gay wing

I did aerodynamics on a program called Ansys, it is very hard to get things right. If you were to put a flat floor in, I would say do a half flat floor maybe from the front to just behind the engine, this will reduce under body drag a bit and not make a big effect on the pressures at the back.
