280Z Front Air Dams

[SoCalJim]

If I install a front air dam, is the rear spoiler needed for non-track use?

I would say not - the rear spoiler doesn't provide enough down force at subsonic speeds - but it looks cool and balances the car (visually at least).

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

My urethane Xenon made a huge difference on my '77. My high speed worries were the wiper blades lifted at about 110 on the speedometer. That's where I lift. ?

[wheee!]

I am hesitant to use urethane on the front air dam due to the flex at high speed. I have seen too many videos of cars on the Hwy with their air dam folded over and the driver oblivious because it looks normal when parked.
Plus I like the classic Jag profile of the rounded catfish front end. The BRE cuts a clean profile of the front.

I think I saw a fix for the hwy speed folding issue but not sure where I saw that at.

I know it can be fixed with reinforcing rods etc, I just don’t think you should have to do that. I prefer the fibreglas versions.

Probably something like mine, works okay now but you really shouldn't have to repair it before you install it, I wish now I had kept my type 1 fiberglass air dam.

I went for the Type 1 fibreglass for the 240Z since fitting the 240 valence is not possible with the lower 280Z frame. Looks neat with the modified 240Z grill.
