Rear end walks when shifting? I finally made it out to the track tonight, first time with this setup:
28x11.50 M/T ET Streets
Currie 9" with 3:90's
BMR SFC
made my own LCA's with QA1 heim joints
BMR lower panhard rod
(both of the above are double adjustable)
Spohn QA - tunnel mount
So, whether I'm on the street driving to the strip or going down the track, every time i shift, the car shifts the back end around??
Is something wrong? Are my LCA's not right?
Is it the heim joints?
Tall tires?
heim joints and tall tires?
just want to make sure i'm SAFE for friday
Thanks!

Just giving this a bump since I'm putting the car up on the lift to check everything tonight to make sure nothing came loose from the 3 shake down passes last night.
Back to the track friday night.

Have you ever raced on ET Streets before? I know its pretty common for them to "walk" when shifting in a M6 car. It happens to my buddies car every time he shifts it at the track. I would try running some more air in the tires that should help out some.

first time with the ET Streets, but I notice the slight shimmy when I have my street tires on I believe
would it be the Currie 9"? I know ford 9" have different length axles, right?

I thought so. What you're experiencing is normal with a locker and manual trans, some call it the locker "side step".....my car does the same thing when shifting slow. Lockers need to have a considerable amount of "slop" in the drivetrain for them to work correctly. Go underneath your car and twist your driveshaft by hand with the brake off and trans in neutral, you'll see what I mean. You can move the shaft pretty far in either direction before the tires move. When you lift off the throttle to shift, the locker unloads and when you get back on the gas after the shift the locker catches again.
Solution: quit taking your right foot off the floor when you shift, ninny.

slack from heim joints?
