I just realized that the 280Z has a deeper front cowl and more curved lower valance, meaning that stock air dams for the 240Z do not fit!

What I am looking for is a spook type look for the 280Z. Not interested in the urethane wraparound style that replace the lower valances. Any ideas from the armchair experts?

 

My front end:

 

 

The issue with the 240Z style:

 

 

 

I’m also thinking about the spook air dam for my 280Z.

Perhaps this might work?

That’s cool! I’m surprised I hadn’t seen that!

That looks nice, thanks for posting it Persimmon240.  I’m not sure about the need for brake cooling duct openings on the air dam.  Do they add any value with the large grill opening?  From what I can see, it’s already a straight shot from the grill opening to front brake calipers.  

You could think of the openings as dead bug collectors - or, perhaps, you could wield a hole saw and acquire some clothes dryer vent hose and build some real racy brake cooling ducts - fog/driving light receptacles(?) - or put some black wire mesh over them and keep people guessing. There are a whole lot of dam options...

Dam good upgrade with dryer hose too...

Dam it!  So many choices!

I believe what wheee! is subtly attempting to point out is that those cavities are actually partially open and direct the air in the general direction of the brakes - no mods required - everybody happy... ?!!!

My main concern is that without the air dam, I will have a very light front end with the spoiler on the rear.

The front ends of S30's do get light at "highway" speeds. Front spoilers are functional - which is why the Euro models came with one from the factory.
