Did you unhook 4 bars and rotate cages, double check no rough spots or binds..

Seriously, get rid of the 275 and bump spring, put what they call for in their baseline. Set LR drop to recommendation and maintain it. Move RR tire back 2 turns on 4 bars at a time. Have you tried taking angle out of PH bar, raise at pinion? Basically.....Put on manufacturers baseline.

What he said^^^^^ esp the j-bar part. Also, soften the rr to 225.

Sounds like you've been changing a bunch of things to try to free it up with no success. If the car is not responding to chassis changes, there's likely a problem you haven't found. Like stated above, get back on base setup and diagnose from there. What is the car doing on entry? Does it roll over on the right side, or 4 wheel slide? Sounds like the car never sets on entry and that kills the whole corner.

You need to return to Barry's baseline. I recommend either a 350 rf and a tall 3" bump ( heavy ) or a 400/700 rf with same bump. 500 lf 200 lr 225 rr. If you are following Barry's wheelbase /axle setup , Trail the rr 1 turn and advance the lr 1 turn on the bars. Also move RF lower ball joint forward of LF 1/8". J bar for crate should be 8" at frame and pinion. Bite 60-80 lbs. 1" frt. 5" fear stagger. 4 3/4" drop on left rear. Both rear tops -4 , lt. bottom @ 3 degree ( 3rd.hole down.) RR bottom @ 0 degree ( centre hole ) Set bottom bar degrees to establish ride heights , driver weight in car. Use J bar at pinion to tighten. I have 2011 setup sheets if needed. These cars must have lots of rear steer, do not shear or back-in except on mud.

put it on standard. itll get you in the ballpark. And best i remember they call for a 400 or 450 rf on base. Also, email lance hes very helpful

take the 2" spacer out of the RR.
moving RR out always feels like it tightens me up.
Just a thought.
