That was about the only thing I didn't try last year lol.

I've never ran slicks so can't tell ya what it would do for you, but I moved mine up to the middle hole and it feels way better. From what I've read the higher holes hit the tires harder, better for slicks. And the lower holes hit the tires softer.

I might have to try that. I'm running out of adjustment again lol.

What are you going to do for rear bumpstops. How much squat do you have/want on a 2wd? And how much room do you have?
With shackles and hangers I had about an inch before it hit the bumpstops. I now have 1/4" thick bumpstops just so I'm not getting axle to frame contact. Otherwise I would have basically zero suspension in the rear.

I have a few inches if I remember correctly 3". I just cut my factory bump stops down otherwise I would have been in the same boat not travel before the bump stop. Haven't hit it yet with racing or on the street.

I would for sure raise the bars up a hole or two.

If you run a pan hard bar so frame pivot point is on the opposite side of the frame where the body torques up, it will actually help reduce that unloading. Spring preload can also help this so playing the cal tracs can help as well.

You have lots of room to play in there and really get it dialed. Just takes time

Not sure why I have less room we basically have the same amount of drop. I still have a full pack just no overload

I probably don't have much to contribute to this, but I'm commenting to follow more than anything.

My RCSB has the same issues you were having. Two springs left, Caltracs and Ranchos mounted behind the axle. I only got it to the track once last year and it would hop really bad on the slicks. Haven't had a chance to get it back out this year (it's been torn apart waiting to get painted) to try to tune it out.

Thanks for posting your info.
