I remember a while back a magazine used expanding foam in the chassis of a 300zx (no not great stuff, but a two part foam that resist water) and they said it made the car handle a good bit better. Has anyone ever used this on ther Z or any other cars with a positive result?

 

Never used the stuff but you should take into consideration that the Z33 is more rigid than the Z32 so the gains would not necessarily be as great as the Z32. You're adding a bit more weight as well. The Z32 made up for this with the ease to bump hp.. anyhow, if you do it do a writeup and take pictures for us not so privileged.

 

I defently wouldnt do it first without someone else doing it with positive results. I image weight wouldnt be a issue it couldnt weigh anymore than a night at the crab leg buffet.
