I guess the track wasn't hooking as well as the last time I was out. My 60' times were a little off and the car didn't appear to be hitting the tires hard enough which in turn didn't get the front of the car working. Here's my question finally, what would you do to try and get more bite:
1. Loosen the shocks up(currently on 5, Rancho 9000's)
2. Move the bar up a hole(currently in the lowest hole out of three)
3. Add more preload(have 1/2 turn preload)
4. Remove rear spring clamps.
Taking a little stiffness out of the shocks will help. I run my Rancho shocks on '1'.
The top hole WILL plant the tires harder. It puts more leverage on the suspension.
If you've got stiff rear springs, I wouldn't run very much preload. Extra preload just makes the suspension even stiffer. You need to soften it up to absorb that extra energy. Just give the passenger side rear a tad more preload than the drivers side, and you'll be fine.
I have some spring clamps, but they never did any good on my car. I can see how they would be nice on the front (no room on my car) but on the back, they just stiffen the suspension up.
If you've got traction in reserve, a stiff rear suspension will more effeciently transmit torque to the ground and get your car moving, but when you start putting more power to the ground than it can hold, some of that force needs to be absorbed by the suspension... and softening it up is necessary.
