My impression is that the roll centers are off the charts compared to the other chassis. With initial setup (3mm) the upper and lower arms are parallel, I've never seen that on any other chassis.

My plan is to put the central aluminum beam and work on the roll center. The problem is not the car it self, it is the balance between the front and the rear.

But for the moment, I'm looking to change the bearings in the rockers by brass bushings so I can have less play (I can make the ground clearance by 1mm without any movement in the shocks, glups)...
Good observation. I sort of eye balled the RC and both front and rear seemed very low. Removing the H bars and thinner shims on inner ball links brought the RCs close to ground.
The car (my first run) was ok with default setup before I removed the H stiffiners on medium grip asphalt and turned pretty well but it suffered wash out on rear on high speed turns while coasting and unpredictable loss of grip in the rear. I removed the H in the front and the rear became more unstable. I didn't have time to try different things other than that. Next time I want to try both H's gone and different oils in roll and heave dampers.
