The location of the spring really depends on the type of track you run at. Dryslick or tacky. If the spring is on the birdcage or to a mount clamped to the axle.
I normally run the left rear spring behind the axle on the birdcage. This indexes the birdcage into the spring with the hikes up.
I have ran the sping clamped up, in the front on a dry track, worked pretty well, but if the track had any moisture or took rubber the car pushed under throttle.
Those are a dryslick type track setup.
On a tacky track I think I would run the spring in the front on the birdcage or on top of the axle. This is just my opinion, I'm sure there are alot of ideas and better ways.

How about running both springs behind i run my behind on the four bar lr and was thinking about running the z-link spring behind or wishbone. Also there are lot of guys mounting the spring on top .

Zero,

Help me in understanding why you would want to run the clamp on a very wet tacky track...I have always heard it being the opposite, running it behind on the wet and clamping it up on the stop and go type dry-slick tracks. As this way tends to give more bite as it does not index with the birdcage...

I went to the Larry Shaw class last year. I had the same complaint room wasn't that good. Didn't spend much time there anyways, the days were so long. Well worth it.
