rear( lower on front )
Tried most of that. Re-attaching the front bar removes steering. I have the body pretty far forward allready. I have tried more angle on rear bar, but going to far on that setting makes the car kind of sketchy. Looking to get more side-bite up front without sacrificing too much in rear. Will try some roll-center changes tomorrow.

Front;
50wt (serpent oil) 3 holes/red springs
lower hole on tower
Sway bar disconnected
Dynamic caster set-up (this helped some, would have to post pics but it reduces caster as suspension is compressed).
35sh Serpent/Jaco
Short wheelbase helped, but had to go back to long for exhaust clearance.
0mm roll center spacers
Rear;
50wt. 2 holes/blue springs
Upper hole on tower
20 degrees or so sway bar
38sh Serpent/Jaco
middle roll center position for lower pins
I have adjusted toe & camber settings through the normal range.
I have also moved a bit of weight forward (1 once of lead to front of battery tray, LiPo battery behind the lead. Result is same weight as NiMh but slightly more forward).
The Jaco 38's test 2-3 points softer than the Jaco 35's! Will try 40 rear/35 front.
Any other ideas?
Duneland, what type of Caster are you running now? And what is your rear droop setting? If I was looking for more entry and apex with the current set-up, I might suggest that the car can't transfer weight to the front fast enough with 50wt oils and 2 holes in the rear. I also believe you might want to try more dynamic caster not less through the middle of the turn.

if i wanted to improve rotation i would consider moving the cg aft rather than forward. have you tried relocating the lead.

avs- Adding the lead to the front of the tray, improved steering. Just not enough to suit me.
Darrint--Will try more holes &or lighter oil. The dynamic caster is achieved by installing ball studs on the upper arms (near the hinge-pin area) & another set of ball studs on the upper plate @ 45 deg. angle to the rear. Connect with a turnbuckle. All caster spacers are removed. As you get deeper into the corner & chassis roll increases, you get a reduction in caster. Increase or decrease the overall amount of caster by adjusting the turnbuckles. Dan Louis came up with the system. I got an immediate improvement in overall steering when I installed it (want more tho).
Will try adjusting roll-centers and shock pistons/oil today.
Thanks for the suggestions.

Any chance of posting a picture showing the area modified for dynamic caster? Sometimes a picture is worth a 1,000 words.

you may also try the WOS steering blocks (the one we where using in the 950R)

Anyway, new rear lower arms will be available soon. Beside being stiffer, the difference will be the sway bar attachment point (more toward the wheel)

Thanks Paolo, I may have those blocks in stock. I'll order the new arms soon.

Don't you want MORE caster while going deeper into a corner instead?

I mean which way does the upper arm move while lifting the wheel, does it go forward?, so less caster angle of the wheel on the track?
