We had the Putzke Fahrpass shocks and polyurethane bushings installed along with trunnion bearings and adjustable camber plates. Alignment now has slight negative camber.
The shop that did the work commented that it was the best handling, best riding, Healey that they'd ever had; an acquaintance who is rebuilding his BJ8 made the same comment.
Cons? None. My recollection is that the shock kit is completely reversible, so don't throw out your lever arms. The camber plates are welded, but also pretty inert and invisible. Doug
