Frankly I can't believe I read through this and the OP( who I am sure is a nice guy and has a beautiful car) is unaware having non adjustable 90/10 shocks on a wheelstander wouldn't be the first thing to throw in a garbage can.
Even a cheap CE type 3 way shock set on 70/30 or 80/20 would have an immediate impact .. Much less a higher quality shock.
