So I did a bunch of flexing while the springs were out this morning. First I have to say, a 4 post drive on lift makes stuff like this SO much easier than a 2 post.
So, springs out, driver side full stuff to bumpstop, pass side full droop.
Here is tire with roll center at lowest point, 6.75"
And here is that same except roll center is at the highest point 11.25"
You can clearly see the difference in how the axle\tire rotate in roll by how the tire ends up in the fender. Pretty cool...
In static form, neither tire ever touches the frame or inner fender. They both come pretty close to the outer fender lip at full stuff though.
In dynamic form, I was able to get the passenger side to rub just a bit, on the outer fender lip I believe. I set the RCH at 9" for my initial test drive, right in the middle of adjustment range.
Upper link frame mount in middle hole, sway bar in middle holes, rebound in shocks in middle of adjustment range, RCH in middle of adjustment range...time for a test drive.
Right away I could feel a huge difference in how the rear end reacted. In hard transitions back and forth at 45 mph the back felt stuck like I've NEVER felt it before. I had a HUGE grin on my face right away. When being a bit more aggressive swerving back and forth I was able to get it to slide the inside front tire just a bit when on the gas...hinting that it's a touch on the tight side like this. Certainly drivable though. I'd race it like this...if I had too.
I did have a wheel hop problem though. It hops hard, from a dead stop, from a roll, even during a hard 1-2 shift. This is discerning and I need to adjust to correct this. First thing will be raising the front upper link up to the top hole. I also want the rear to roll just a bit less so I think I'll put the rear sway bar on stiffest hole and might put 185# springs in place of the 162# springs in it now. The stiffer springs and more rebound in the shocks may help tame the rear axle down as well.
Hopefully not too many changes at once and it'll be enough to let me feel like I can beat on it a bit harder next time out.
I'm also not sure if it's just the extra noise, or if the tailpipe delete option really opened up the exhaust, but it sure feels peppier when on the loud pedal!! Could just be the car forcing itself forward faster instead of just spinning the tires too.
