Should I do it?

[agemeansnothing]

If I put a front airdam a normal one from Victoria British does it make any improvements for the Z. What should I look out for if I do?

What are you asking ? If YOU like the looks , this is what is important. The only improvement to the performance of the car will be at high speed . For a street use car , mostly it is for looks. REALLY . How many times will you be driving above 85 MPH ? I know I am going to get FLACK for this . but it is the trooth Gary

I was wondering at high speeds what it would do for the car( I need to learn how to expalin better sorry) thanks.

I have an old MSA air dam and a BRE rear spoiler on my 78. I don't really notice anything at normal speeds but at freeway speeds and up they seem to keep the front end down. The front end of Zs without a front spoiler/air dam tends to lift at higher speeds.

Ha maybe then he could spot me some dough!! I WISH!

I think most air dam kits are for looks. (I have front air dam and rear spoiler)

If you want aero to make a diferince you will be driving a race car.

I drove formula mazdas at sears piont (Jim russel racing school) the race cars had wings but did not make the downforce nessary to afect the handing in the fast turns. (turns 1 3a 5 6 8 9 and 10)

beandip is right in the fact that you will trim aero drag making top speed less stresfull.

this may be a dumb question, but hear me out.

in trying to keep the stock look, i wonder if instead of an airdam, the addition of the splash pan to redirect the incoming air would prevent or help prevent some of the lift? i know most drivers say high speed will cause the front end to get squirrelly. if it's because the incoming air is getting trapped under the hood causing the lift and if a little of that air could be blocked.........

even maybe the addition of vented inspection lids (there goes the stock look) just to give an air outlet to reduce the pressure and subsequent lift. i know some owners use them to lower underhood temps by providing an outlet.

or is the lift generated from some other factor?

Too understand how air afects the stability of a car you have to think of how an airplane flies. (the air travles a further distance over the top of the wing to cause lift)

Downforce is cerated by air travaling over the car will create a vacume under the car to induce downforce.

Race cars get the body work close to the ground and install panels under the chasis to improve this vacume.

This only happens at very high speeds.

If your car feels funny a high speeds I think it a susption/alingment problem

Well, that explains why my front end lifts at 115 mph. I guess I didn't have enough balance weights on my front wheels!

Hi rob

when you are going that fast in a mostly streat car (Very high speed) i can see the problem. too much air has no place to go i.e vents in the motor compartment (or hood) neer the the wind shield would help air flow.

I was trying to help explain that a streat car aero package does not help handling .
