Ive been on the lookout for something along these lines aswell.  I like the ve gts single pipe one.  Im running rb25det gear with only one exhaust exit.  Do you think that would look alright or?


As above mate... wont fit due to the curvature!!


Diffusers looks great on zeds but keep in mind even getting one specifically for S30 will require a fair bit of work to get it fitting correctly as 95% of rear ends have been bumped/twisted making it hard to fit up something like this.

Yeah I wouldn't be too keen in buying one from another car and trying to make it fit...

Looks like the demand is there for someone with the skill to make up something good from scratch and make a dollar.

freddy is certainly the man to see.... though from what little i know for a diffuser to actually be functional the car has to be extremely low to the ground(no 100mm is not low) so this piece would be purely for aesthetics. Maybe freddy can chime in on this??

The closer you are to the ground the more effective the underbody aero will be. It would not be noticeable on a road car because of the slower speeds obviously but if you were to put that same car on track with a rear diffuser even at a fairly high ride height it would make a difference even if it's just because the strakes are straightening out airflow.

Alternatively if you were to raise the rear of the car enough to give it some noticeable rake the pressure difference between the front and rear of the car will also create a diffuser effect. I toyed with the idea of creating under car panels to make the zed have a flat floor but it is much easier than it sounds, plus the old girl would be quite some way off the ground!

Gents I don't want to rain on your parade. But unless you have a real fast Zed and I mean real fast and take it on the track then I reckon you wouldn't notice any difference having a defuser. Unless you are just going for the look.
If all you Zed fans are after aero dynamics then you need to start at the front of the car. Not the rear. That would be with a G-nose. Other wise you really have a massive parachute at the front if you are running a standard front grill. Not enough down force with a standard front to even make a rear defuser work in my opinion. Then you would need a big wing at the rear to keep the wheels on the ground at high speed. Oh and you will need a fast motor as well. Then and only then would I be looking at spending money on a rear defuser. But even then if you are running a standard rear bumper you are creating unsettle air turbulance around the rear simply by the way it is attached.
Personal opinion only.  :)

Pretty much the only guy here that needs one, has one.
And that is Sinisha!

But I think they are talking about want, not need Craig.  ;)

I just like the look of them, I was worried that the rear of my de-barred z was going to look abit plan.

But the diffuser will break that up, Im not too worried about performance yet :)

I think we should clarify that most of us here are only interested in adding a splitter to a shaved rear end for aesthetic purposes only. These are street cars. We don't need to debate whether they will work or not. We know they won't, hence the reason we've mentioned pinching ones from existing road cars.

Nice job Patch.
Can you use any of these 'nicer' ones?

Tim if you look at the one I done above it looks fine, look at where the pipes are to your tank,  but when I try and put one on your rear end with your pipes so high it doesn't work and shows the bottom white and tank.
BTW yours looks a lot better now with the 4 pipes, just needs chrome tips and the right pipes to line up the same.

Thanks mate. So you need a pic taken from a higher angle. Only the two outside pipes are connected, the inner pipes are dummies. Gives people an idea anyway. Maybe someone else has a pic of theirs.
