-- Well, from all your previous posts I seem to get that you simply don't
like bolt in front suspensions. I fail to see how 8 bolts on an
original
suspension is different then 8 bolts on an IFS. Do factory engineers know
magical places to put their bolts? I doubt it.

-- True that nothing takes the place of experience, testing and
money. I'm not arguging that, but it seems like there are so many camero
clips, pacer crossmembers, and aftermarket suspensions out there that work
fine every day. Did all these people just get lucky.? I really think
there is not as much to this as you would have me believe. I'm not going
to the moon, I'm building a truck.

-- Please dont' tell me that every Tom Dick and Harry is designing
suspension. I see quite a few different manufacturers, but as someone
already pointed out, they had to start somewhere. Too often, the little
guy gets discounted in favor of the guys with the money. Lots of times
bigger isn't better, and sometimes bigger is worse because it's harder to
change things. Anyway, I do know a little about racing suspensions, I
race motorcycles, where suspensionn is the most critical factor in the
setup. I would trust my race bike on the street any day, just minor
changes to the damping setup... I just wouldn't want to wear out that
suspension on the street. I wouldnt' say it's not up to every day use
though.

-- I guess I'm a little confused. Seems like you dont' have a problem
with the pacer set up, which was designed for a small car, but you do have
a problem with a suspension system that someone acutally tried to design
to work with a specific application?
