Questions about airdams

[Darylick]

First: a shout out of HAPPY NEW YEAR & Kudos to Mike and the other Gurus I've learned from. It's about the Z.

Though I voted for original style in the "How do you like the front of your Z?" poll, I did notice, in the three weeks I was able to drive my Z the front floated at Higher speeds (I thought this was a result of bad ball joints, shocks or alignment) Would like to here more on this subject.

Questions: First: are the urethane airdams offered by MSA or VBL the same, and who is the manufacturer or other outlets? Second: Does this replace one or all of the three pieces that make up the valance on my 77.

Thanx

I don't know who makes the Urethane airdams, but they replace all 3 pieces of the factory valance. An airdam will at least minimize the lift or "float" that is inherent (at speed) in the stock front end.

Check the "Links" Section of this site for Z car Businesses that offer body panels.

The "spook" series of spoilers didn't replace the valance, they just bolted onto it.

The Motorsports catalog lists these as being for the 70-74 vehicles, but that's due to their being bolted on to the lower front valance and turn signal corners. Since the turn signals moved to the grille area after 74.5 (with the introduction of the "fat" bumpers) the valance area changed.

I'm not real familiar with the area down below on your 77, but I can't imagine why it would be so radically different from the early Z's that the spook spoiler wouldn't work.

Give them a look, they're items numer 50-1521 and 1522. One has ducts the other does not. Both are fibreglass.

bambi killer you live in pleasenton? i live in castro valley we should meet up somtime, let me know

Dero , where did you get the air dam you have in the picture of your 240 ?

Another important thing you can get out of having an airdam is forced air onto the calipers and rotors -- by adding ducting you effectively improve the life and effectiveness of your brakes.

duh -- that is if you run the ducting from the airdam to the brakes...

Sorry too much holiday cheer. ROTFL

fiverglass aero damn from msa or the spook

the urethane airdam does nothing but look good

they bend and flutter about at highway speeds and are only good if you dont want them for any reason but to have one on yoru car.

Damn, I was recommended urethane over fibreglass because they don't crack when hit by something, eg the curb when parking.

Do they really flutter that much at speed?

[hmsports]

They will curl under quite a bit and the front will most likely bottom out on a good bump. You can help this by adding some aluminum bracing behind. There are a couple of other threads that explain this technique.

Hi

The urethane lower valences are 90% made by XENON

(Check out there web site for a pick.)

I bought mine from work for $150.00can.I was really surprised with the quality you can litterally just wet sand and then bolt it on

I have heard that the middle starts to sag after a while so it should be reinforced with some sort of a bracket.

A freind of mine is still painting mine so I am not sure if the sagging is an issue yet. Oh, you have to drill your own mounting holes. I have seen the newer model spoilers, modified to fit the older cars to get rid of the turn signals.

IMHO the "BRE spook" style spoiler looks the coolest the only reason I did not go with it is the lower valence on my car was rusted to heck. and it is fiberglass so not as durable as the urethane.

Last words

adhesion promoter and flex agent are very importent for a durable paint finish.

tell me if im mumbling
