Difflow will build one to your measurements,
Does your GTR have a flat floor?
Probably not going to do much otherwise.

i looked at lotus ones, but they will hit the rear clip when you open it..

a real defuser will run from the front crank pulley rearwards at an angle of 10-12 degrees to work effectively so flat floor and paneled under engine and gearbox critical too.

You need to balance the car so will need aero upfront too, so dive planes and splitter.

If it's just for the 'look' at the rear then there's always the Reverie (although it's a bit expensive for a piece of bling):

Try Steve Smith

wow!
thank you all.
F.C. :the floor of the my gtr is mostly closed with aluminum panel, except that the center-gear-box and oil-sump for cooling.

I do not have the additional front splitter.

Dom thanks, you're right, opening it will touch the asphalt.
You should try to aerodynamics in a wind tunnel.

has anyone tried to speed with diffuser?

CHUCK: most expensive!!!!
RACINROJ: fantastic look but how much euros?

however, i looking the web, I have seen several gtr with diffuser, especially the racing versions.
I believe is useful to give direction and control to the rear
what do you think?

it is unlikely that you going to benefit from the aero effect without a fully closed floor.
if you have the engine bay open to the floor you will lose any useful airflow right there.

I like the SS diffuser.... how much and does it allow the rear clam to open normally?

That's the point.
What happens when you open the rear clam?
I think the only way to install a proper diffusser is by modifying the aperture of the engine hood. In any other way will be just a cosmetic item.

This is an example of a functional underneath aeropack. Difficult to fit on our Ultimas. (I guess)

Plus the car needs to be a fair bit lower to benefit and as pointed out, the front needs balancing. With a fully effective diffuser at the rear you'll at least need a full width, large front splitter and some way of letting their escape better from under the front clam.

The SS one allows the clam to open normally I'm pretty sure.

[845ste]

ok, but, scuse me, nobody here has tried in the track racing , with and without diffuser?
what differences please?

if the rear part of the rear clam was bolted in position and only the top was opening then yes this would work fine

Agree. As in the Moslers, by example
