Need Help deciding!!!!


Recommended Posts

My 1973 240z is just going in to get sandblasted then primered and painted....and was thinking of putting an aftermarket air dam i have seen tonnes of them and i have no idea what they are called...If someone can tell me the names of the following ones (in the pics also the grill on the last 2 blue one) i would greatly appreciate it. Also any restoration ideas or tips would be appreciated as well

Cheers!

The air dam on the car with the grill is different from the rest.

 

The general shape you are going for is more or less the standard-ish shape for the aftermarket air dams on these cars, and is also my preferred look; but aerodynamic testing seems to lean strongly towards the MSA type 3 unit being the better performer.. I am GROSSLY over summarizing a vast amount of data in making that blanket statement, because any air dam requires a bit more than simple bolt-on installation to serve much function.

 

Okay, that being said, you can go to http://www.zcarparts.com and find air dams that look like that, quality pieces bought my many. I would recommend urethane over fiberglass for durability's sake... I watched my uncle hit a cone with his fiberglass airdam on an autocross course in the most beautiful Z I've grown up with, and saw it shatter the airdam into a million tiny pieces, and he has had his black urethane piece on there since then.

 

Urethane flexes, which leads to its own issues in installation. Sometimes you need to add a few extra little braces to hold/set the piece into its proper shape, but for a street car its normally recommended.

 

The grill appears to ME to be a custom made piece mimicking the stocker... It may well even BE a stock grill that is simply immaculately finished. Take a look at your grill and see if you can't find a way to make something along the same lines as that; its NOT as difficult as you might think, with the right fabricating equipment. A Miter box type cut, repeated say, 10 times in 4 upright pieces, find the right piece of channel for the cross-piece, quick tack welds, and finish. Bend the channels first obviously, thats the hardest part.

Well you can find air dams almost at any site that carry Z parts. MotorsportAuto, Zspecialties, and there was two more I can't remember right now. try doing a search for carbon fiber zg flares. you should get 2 sites Motorsport Auto and the other one. As for the grill they are JDM or custom grills from what i can see. MSA has JDM grills and there was a custom grill on ebay a week ago. It actually looked pretty good.
