Could only find info from a while ago so thought i would share my experience
Found with having 19's on the ute that continuous axle tramp ( take of from lights or going round corners mainly) that i was causing extra tyre wear and damaging the tyres as well as feeling like the back end was going to jump into the ute.
After sussing out underneath and talking to several people i fitted an extra urethane block under the rear diff crosmember
Part No. for kit is SUPER PRO SPF0840K
From what i have found out this block ( not necessarily super pro bushes but similar ) is also fitted to HSV vehicles - yet to see one to confirm if true
BUT since fitting the bushes i have got rid of all axle tramp
What a difference it does make-a little extra road noise but not enough to ruin a nice drive in the country with no tramp and better rear end feel and control
Also for those interested, in the kit you get bushes which also go on top of the crossmember replacing the original rubber unit
I fitted these then removed next day and refitted rubber bushes due to excessive road and diff noise and a much harsher ride-would be good for strip use but not for road use
ALL IN ALL VERY HAPPY NOW
