I've read the suspension thread many times, and it still does not answer what the OP is asking: it does not explain or give examples of differences it just says "The best for your ride" or discusses the results on a S13 or B13, not a B14. It also mainly only talks about the front bar (unless the Sport Compact quote is in reference to the rear, sort of hard to tell) and once again both I and the OP are speaking about the rear. I think he is looking for a little more insight into the situation like: "The ST was fine, but I noticed considerably more understeer in non-banked corners greater then 45* and could also exit most 90* corners at 10 to 15 mph faster", not just it's the best. Actual hands on examples. Rodney I think so far would do the best with this seeing he's had both bars on his car, though (and I'm not 100% on this) I think it was on a B13, not a B14 so results might differ. I don’t think either have invited any real flaming, just looking for more insight to a question then “it’s better”.
