Reply to "Adjustable Rear Camber Bar"

Chris, there are a number of designs sold but the best IMHO is Hall's square steel adjustable bar. This is currently the only commercial bar that has long ends that socket into the welded fender pockets, to take the cornering loads in the bar, not thru a pair of sheet metal tabs with slotted oversized holes & undersized bolts.
The Pantera usually has relaxed it's rear suspension such that the rear camber adjustment is maxed out and is still around -2 degrees. And while this is good for cornering at high speed, it's bad for inner-edge-wear on our ever-more-rare & pricy rear tires. With radial tires in 275 or larger widths, zero or minus 1/2 degree camber is a good compromise between cornering and edge wear.
So by being patient and adjusting a LITTLE pre-load via the adjustable camber bar, over a period of weeks you can usually progressively tease the rear suspension back to zero camber without issue. NOTE- if you get impatient and try to brutalize it back to zero all at once, you usually buckle one or both fender panels.
