Does anyone use strut tower braces and would you recommend them for "aggressive street driving". No autocross (yet).

I never used them on a street car, but I did on the race car. If you plan on autocrossing in the future it would be a good investment. Are they a necessity on the street? Maybe. It might stiffen up the chassis enough to affect the ride, then again it might not have any effect depending on your suspension set-up. If you are running a stock set-up, they probably won't help much at all, if you have modified the suspension, they probably would be a benefit. I guess it is all up to you, if you have something that is more important to spend your money on for the car now, I think they could wait a while. If you are really serious, the only strut bar that will make a definate and huge improvement in the chassis of a Z would be the one that was advertised here that ties into the frame rail and the firewall. Just tying the tops of the two towers together only limits the flex of the chassis in one plane, the towers may not flex, but what they are tied to might.

Sorry, not much of a decisive answer, but hopefully you get the point of what I'm trying to say. :cross-eye

Some cool pics of them. I myself have never put them on A 240Z.

I did put front & rear ones on my RX7 and could feel the change.

Yes it was for the better.

Here is the one 2many was talking about and the link to that post. http://www.240z.org/forums/showthread.php?s=&threadid=2889&highlight=strut+bar
