Maximum Motorsports Height Adjustable Rear Lower Control Arms for 1979-1998 Mustangs.Features: The spring perch design allows easy ride height changes, with the car still on the ground. Road racers and autocrossers can set not only the ride height, but also corner weights, for optimum handling. A car can be fully loaded up with gear for a road trip, and then have the rear ride height adjusted back up to normal, to avoid bottoming out. These control arms have the mounts for a factory-style rear swaybar.
Adjustment: The easy adjustment of MM's Control Arms allows raising the rear ride height up to 2", or lowering it as much as an inch. A heavy-duty weight-jack bolt, similar to those used in NASCAR, makes this possible.

Jack: No problem, Bill. For the '79 to '04 cars, we have our heavy duty lower control arm with an adjustable spring perch on it. This model has a spherical bearing in the rear half. It has a 3-piece polyurethane in the front half to allow easy articulation and smooth motion. The adjustable spring perch gives the owner the ability to adjust the right height with a 1/2" ratchet. They just stick it in the bottom of the control arm, and they can raise and lower it easily. This is especially useful if you have a drag race car for instance, and you take it to the strip, and you put large slicks on it, and you need more tire clearance. Or if you're a road racer, an auto crosser, and you drive the car to the track, when you load all your floor jack, jack stands, tires and everything in the car, when you get there you want to have the car low, but during the ride, you want to have enough ride height so the car's not bottoming out. You can raise it up for that, and lower it at the track.
On this side of the display we have our extreme duty lower control arm. This unit has a spherical bearing in the rear like the heavy duty model, but it also has a spherical bearing at the front. The bearing isn't visible on the control arm because there's polyurethane thrust washers used in the front to keep the control arm from rolling when the spring load is applied. This particular model does not have an adjustable spring perch, it has a fixed spring perch. It's a little lighter than the other model, it's a little less expensive, and it can take higher power levels. We offer combinations of extreme duty with adjustable perch or fixed perch, and heavy duty with adjustable perch or fixed perch.
Bill: How's the NVH going to be on the extreme duty by getting rid of that normal front bushing and going into that sleeve?
Jack: That really depends quite a bit on the condition of the car. For example, if you have a full interior car and it's a later Sn95 model, the NVH difference won't be that large because the sound deadening, and the rear seats and so forth will absorb a lot of that energy.
Bill: On a race car you'd probably hear it more, but you can hear everything else anyway.
Jack: Exactly. On a race car it's going to be much louder, but it's irrelevant.
