I tested the first slide-a-link on a stick car, and believe me, it was ugly. Moroso worked with me, and I believe the later version slide-a-links are very good. The front bracket needed to be made from heavier material, and the rear plate also needed to be thicker material. In A/S, 3570 pounds, I have been mid 1.30s on a decent track. In AA/S, just over 3200 pounds(because I can't get to minimum wt.), I have been 1.29 on 9 inch GY's and 10.5 MT's. I don't have first hand experience with the Calvert bars, but I think you can get more adjustment(pre-load, side to side balance, etc.) with the slide-a-link. It is very easy to get either of these in a bind, if you stiffen the shocks too much. BTW, the Calvert split spring is great.
