Rear upper control arms...

[johnny_munyak]

Have a chance to pickup some Edelbrock rear upper control arms for a decent price. Was wondering if they are a good improvment over stock.

How do you go about setting them up properly?

yeah, I think the new bushings in the arms that make the biggest difference.
the solid tubular ones just get bolted in, are they the double adjustable ones?

If this is a street car I would pass and just install new rubber bushings in the stockers.

We performed extensive testing of rear upper control arm bushing materials during the development of our Panhard Bar. When retaining the original four-link suspension, the best compromise between resistance to suspension bind, best control of axle position, best ride quality, and least potential damage to the chassis, is to retain rubber bushings in the rear upper control arms. This is especially important when adding a Panhard Bar. The compliance of a rubber-bushed upper control arm is required when a Panhard bar is added to the Mustang four-link suspension.

Yes. They are the double ajustable with urethane bushings.

Thanks for the help. I`ll pass and look into the stiffer bushings as per Maximum motorsports.

It's a lot more work to replace the stock ones, and costs the same as just buying new control arms.

with the double adj you need to get an angle finder with magnetic base, then you set the rear at -2(street) to-4 (race) degrees in relation to the driveshaft. I set mine to -3

So what if you are not intending on installing a panhard bar from Maximum Motorsports? They don't mention anything about installing them if not using a panhard bar?

Are the rear upper control arms hard to install?

Changing the upper and control arms is very straight forward. It's 4 bolts, 18mm heads.

I have the same ones and I love 'em. Combined with MM lowers, suspension bind during hard cornering is almost eliminated and the rear tires stay planted on the road.
Definitely good for the street especially if you like corner carving, and overkill for the strip where you're only going in a straight line.

There testing on the bushing were during the development of their panhard bar.
