What's wrong with the Pfadt? I thought that bar did a good job, no? I've read that the alternative is the ZR1 like you mentioned. Shoot I've got 1.57 60ft on a 275/40-17 drag radial on my base with a rear Z51 sway bar.

I believe the Z51 is the same as the z (27mm) Zr1 is 31mm I think.

Interesting.....
So, I can grasp that they don't behave like a solid axle. But...is it as close as "we" can get to a solid axle ??
If not, I'd like to hear how an IRS can slow the "independent" nature of its design.
Thanks ....

The IRS setup still has engine torque, but because the pinion can climb the ring gear all it wants, it doesn't act upon the chassis, due to the fact that it's decoupled from the half Shafts. The diff/torque tube twists, but what would normally transfer load to the chassis, it simply can't now, because the halfshafts do not allow for load transfer in that direction.
Make sense?

The two forces you have acting on a standard, big sway bar, solid axle car, are the engine torque- and pinion torque.

Makes total sense....and is why you never see a late model vette only lifting the left wheel like typical chassis car, the torque is evenly distributed.
So...you didn't really answer my question. How can you "couple" the sides, as to act together ??
I'm not chassis expert, but it does seem that....with adjustable end links and a "stiff" bar would force the sides to "mirror" each other ???
Thanks.....

Could be because you're auto and you'll already have load on the suspension when leaving on the footbrake.
