Running 72 Buick Skylark, I thought I saw in a Steve Park book that he disconnects the right upper control arm on the street stock in the book. Is this a good idea? If so waht does it gain? Thanks, Race I loaned out the book and it has moved out of town.

I would think that would let the rearend move to the left and probably rub the right rear tire on the frame or break the other side.

Did you mean you saw it in a Steve Smith book?

Mud,

The reason it was disconnected in the book was because of a panhard bar. If you can find it again, it says to disconnect the driver's side, not paas side.

I have the very book you speak of Street Stock Chassis tech.

Raceinmud, I have that same book, and I decided to try the set up Steve Smith is talking about.
If you leave both the uppers hooked up and install a panhard bar the arc the end of the bar (on the rear end side) makes the rear move slightly from left to right---but the upper links won't allow that lateral movement and it binds up.
If you disconnect one of them, what my experience was, the rear rnd moves with the panhard arc, but also "rolls" changing the pinion angle dramaticly.
This I did and it really (I mean really!) worked. I asked track tech if I could change the angle of the upper link to stop the roll.
Then, using the stock upper trailing arm, I made a mount directly on the top of the rear end housing (center between the wheels)Straight in front of it I fabed a mount for the other end.
I used the stock rubber bushings in that arm and no bushings in the other arm. So that it remained a "stock" four link.
I won a lot of races with that set-up...but all good things came to an end when tech finally figured out that I'd constructed a three link suspension using stock four link parts.
Good luck!
