Phil,
I had an O ring failure in 178. I still had to pull the stub axle to fix it.
755 had a seal leak within a few thousand miles of installing the ERA rear. I think it was just one of those things. 12,000 more miles with no other issues.
I don't think the Jag design is any more prone to leaks than the ERA design. In my opinion you gain cool factor, save some weight and get bigger brakes.
Oddly, I probably saved some cash on my rear change because I had a 3rd member ready to install that I got a great deal on. Also, I found a guy that wanted the Jag rear and front brakes as a package for his ERA build. I pulled the rear as an assembly and sold it. The profit from that off set the cost of the new parts.
The 4 piston front brakes and parts to build up the ERA rear are plenty expensive. I think it was in the range of $6k.
