Rear Spoiler and Front air dam

[J.Larr]

Which rear spoiler is the best considering downforce and drag at highway speeds for my '82 turbo zx? Also the same question for a airdam for use with a intercooler?

What is the stock ride height for my '82 turbo zx? And where is it measured?

I would go with what you like best. My guess is that most of them are going to be about the same but the way it looks should be your preference.

I'll ask a few people and see if I can get that answer for ya.
