I am going to purchase an extended arm set.
Because;
1.The axle is not quite centered left to right,(About 1/2 inch as measured from fender to tire.) and adjustable uppers will cure this.
2. As the car is lowered, I rub slightly with two adults in the rear. centering the wheel in the well will cure this.

However. Which to buy? It seems the METCO is a higher quality and you can adjust the uppers with out removal. BUT METCO moves the wheels 3/4 back. I think this is too far and the wheel will perhaps be then favoring the rear of the well.
Hotchkis is only 1/2 back but their arms don't seem to be as good a quality.

any help out there from all you experienced B Body owners????
Thanks.

Hotchkis moves the axle only 1/2" so you won't need an extended driveshaft which is a must for metco's.

METCO says that a extended drive shaft is not required.
Hey George SS;
When you installed the METCO arm set you said that the 3/4 is not too much, did you have to replace your Drive shaft? If so what one did you use?
I have a Borla Cat back. I am also concerned that moving the axle back 3/4 may cause trouble with the tail pipes since I have already lowered the car with Eibach springs (about 1.5 inch drop). any help here?
Thanks.

Couple notes :

1. If you value your tranny tailshaft, you need the extended driveshaft with the Metcos.

2. The adjustable arms will NOT fix the axle being off side-to-side.

3. Centering the axle (front to back) probably won't fix the issue of rubbing with a lotta weight in the car. You're better off with airbags in back (the $65 Airlift ones from Summit that you inflate thru valves you can mount behind the license plate will work fine here).

The tire clearance issue will probably get worse when you move the axle back, the cut out in the sheetmetal isn't centered over the wheelwell in the frame, but the axle is centered in its spot in the frame. there was a problem where one side of the axle wasn't centered in the frame, but if you look at every 93 up B-ody out there with stock control arms, you will notice that the tire and sheetmetal cutout are not centered, its the sheetmetal though, moving it back may cause clearance issues on the inside edge of your rubber.

I have the METCO's and the 3/4-inch longer is perfect. I don't think 1/2-inch is enough. I also have the Borla exhaust and there is no problem there either.

I do have the extended driveshaft. Not sure if it's actually needed, but I got it because it's also good for a few HP (lighter rotational inertia).

OK
This helps alot! Looks like I will go with METCO and a extended drive shaft. Any suggestions on sources. I see one offered by NAISSO.

On the side to side axle adjustment;
Funny. I have a triangulated 4 bar installed on a pickup. The triangulated design is similar to that of the B-body right? well the two upper "angled" bars act as the pannard bar of a four link. On my pick up if I shorten one bar and lengthen the other a equal ammount the axle shifts side to side. Just like changing the length of a pannard bar. My rubbing issue is with the outer fender trim on the drivers side. Just a little. I have a ton of clearance on the passenger side.
I just thought the METCO arms would act the same way.

Thanks again for all the help out there!!

Ed Runnion,

I understand that aftermarket Control Arms won't help the side to side problem. Do the aftermarket arms cure the front to back wheel centering issue? My left rear is about 1/2" farther forward than the right. My understanding is that a hole was drilled in the incorrect spot on the axle's LCA bracket.

Thanks.

Cruz-lo : issue is that you need to move that axle a LOT in this case. And moving it that much side-side is almost certain to cause bind in the lower bushings. Frame shop work (i.e. bending the frame and/or redrilling holes in the frame to relocate the mounts) is in order to do it the right way.

And no, the LCA will do absolutely nothing to help the frame being mis-stamped. Need to get a good frame shop on that one, so they can fix it AND get everything true/aligned properly afterwards.
