Jamo,
Stop holding back and tell us how you really feel.....
I've seen the aluminum rears and they are very nice, but what is the advantage? You can't see them, they have the same internals, and as far as weight savings, what does 20-30 lbs really help in these cars?
The 9" Ford sounds interesting on the surface until you realize in a 2200-2400 lb car, how many people have really had any problems with the Salisbury or Jag rears? When it comes down to cost/benefit, IMHO, the money can be better spent on quality items elsewhere.
