Re: lift size for tires...
What is it about the longer shackles that cause this more than the lifted
springs?

springs move the whole axle down, keeping the geometry. Where shackles just
move the back of the spring down while the front stays put, tilting the axle up.
I wonder though how 1/2" of larger shackle could do that since it probably puts
all of 1 degree (or less) into the equasion. It's more likely the increased angle
is just beyond what the stock U joints can do reliably and Mike would be better
off with a CV joint conversion and prolly a slip yolk eliminator.

Somewhere out there I saw some shackles that could extend quit a bit
but were held closed by pins for on-road use. Revolver shackles?
Don't follow this too much, my springs are the coiliy type.

Hi Doug,
Last Saturday night you had a suicide bomber blow himself up
outside your stadium, he was only outside because he wouldn't let
himself be searched. It went off before plan B, he would have been
surrounded by students after the game. Anyway, the whole rest of the
nation doesn't know about it, do you? was it on your television?
