Bump steer question

autoxcuda said

I run 1.14” MP bars.

.81 MP drag bars are rated 90 lbs/in wheel rate
1.14 MP bars are rated 350 lbs/in wheel rate

I’m almost exactly 4 times as stiff as a drag bar. And think, there guys out there with 1.24” t-bars !

At 1” compression or rebound I’m about 1/32” bump steer

At 2” compression or rebound I’m about 1/16” bump steer

....Not bad

Not bad at all!!! :thumbsup:

My 1.12's are "only" 300 lbs/in.

1.24? I've heard that some of the old track cars swapped their torsion bar anchors over to C-body anchors so they could run bars larger than 1.24". The A, B/E body hexes are 1.25" so the max diameter is 1.24". Some of the C-body cars had 1.41" hexes, so if you swapped to those anchors and pivots you could run a 1.4" bar. :eek:
