Folks,

I guess I understand the usefulness of adjustable upper arms. Could someone explain to me if adjustable lowers are needed on a street car that will occasionally make a 1/4 pass or two (or occasionally smoke a rice boy or two)?

Thanks

Nope...not needed on a street car. :noway:

The factory shipped a lot of these cars with non-adjustable arms in both top and bottom. So obviously they are not required

They can be desireable to adjust pinion angle and/or tracking alignment. The upper arms will change pinion angle alone. The lowers can change both pinion angle and tracking. Thus the lowers are both more capable and more complicated to adjust.

Only thing they may gain you is the ability to exactly centre your tire in the wheel well if you're running really big tires and something is slightly out of alignment.

Thanks for the replies. I am going to get the adjustable uppers for the pinion angle adjustment. That way, when I do my TKO 600 tranny swap I can make some adjustments. I'll stay with my boxed lowers.
