Proturing or roadrace rear suspension

You mean, this one? On the Gurney AAR.



You can just about see the other end of that set up in this picture. Man I wish I had a higher res version of this one...



Yes, absolutely the rules. If you're planning on actual competition, instead of just having fun, what's "best" is usually immaterial because it's probably against the rules too. :evil3:

And don't get me wrong, I have all kinds of stuff that I've done to my car that doesn't probably make it any faster. Not really anyway. Makes me feel better though. ;)
