Hey Martin, I've seen subframe bolts pull out of the frame rails, frame rails
begin breaking spotwelds as well as the same for the subframe itself.  I've
seen this in two instances.  The snub mount actually does not create any
stress on the chassis, it simply stabilizes the front of the motor, when the
motor is static there is no weight on the snub mount, same pretty much goes
for the Delrin driveshaft bearing.

Not saying that solid subframe bushings _cause_ the problems I've stated
above, but definitely correlation existes since i've never seen these
problems with the stock rubber bushings.  I have a set of Delrin Subframe
bushings I'd like to put in soon, so I'll let everyone know how they do.  I
believe in a true race car seam welding the unibody and subframes will
prevent the problems I've described above.
