Lift bar

[keeks]

I just see that solid 5th (bushings) as a potential bind. Aren't we constantly trying to find and fix binds?

Lay under your car supported by frame on jackstands, fifth coil shock removed, rr coilover removed. Lr hanging on travel limiter,RR jacked up to simulate dynamic ride height when exiting /cornering Lift and return to static position the lift bar and note what the entire rear axle assembly does! The amount of travel the 5th coil or whatever you bolt there's travel has has a pretty substantial influence on handling/tracking overall dynamically, not just traction to the rear ties from leverage.

Also note how much the pinion mount of the j-bar moves up. I think this if often overlooked or simply not even considered.

I see alot of Mod guys out west are now running a behind the rear end pan-hard bar of some sort to combat this, pivot point raising up while the rear end is wrapping up.

And now you have plenty to consider with the liftbar you have!

Are those sport mods? I believe they have to run the panhard to the rear as per rules.

Yes, those would be sportmods if they are running IMCA which is most tracks "out west". All of the Modifieds are using J-bars with pullbars. You will be hard pressed to find one that's not. Didn't modifieds in the 90's and early 2000's use a similar lift arm setup as the nueline but instead of the rod with biscuits I thought they used a chain with a spring. I vaguely remember seeing one and hearing that they built a ton of forward bite but never drove one for myself.

UMP, USMTS, USRA mostly around here and lifts arm aren't as popular however there are a number of them and many of those VERY successful. Like track champions and national champions levels of success.

They had liftarm for decel and pullbar for accel. Can't have both now by rule
