Some lowers, like the Megabite Srs have Heim joints at both ends which provide adjustability. You can accomplish pinion adjustment with these just the same as with adjustable uppers. Once I've set my pinion angle, I rarely ever change it. As a matter of fact, I have been all over the place this season with pinion angle, all the way from -6 to +2 and it doesn't have any appreciable effect on my 60' times. I think the pinion angle is much more important to a car with the stock rubber bushings everywhere since it counteracts large movements of the pinion under acceleration. In a car like mine that is very stiff in the mounting points there just isn't much pinion movement at all, at least as far as I can tell. I've got an adjustable pinion snubber on the car that I dress up with shoe polish and I rarely ever see it contact on the snubber plate.
