I rang Ash @DVS, bought lowered H&R springs plus Nivomat rear shock conversion mounts to Bilstein B6's shocks, and above all really good advice.
Ash knows his stuff, very helpful. Bought one of DVS strut braces as well because of the stiffness of springs, & struts, B6's, so the applied forces of the suspension now form a rectangle as such, and worth every cent, quality work.
Revzone in Melbourne for Bilstein B6 struts & B6 rear shocks, $1200 delivered to the door in NSW.
I'm very happy with outcome car rides flat & direct, a bit stiff at the moment, but everything is still new & will settle in after a few thousand klms.
Rear sway bar is standard but I'd like to increase diameter of front bar a bit, cornering being the reason.
About to replace all rear sway bar mounts and rose joint mounts.
You'd be very lucky to get out of it for $1500.
I budgeted $500 per corner, replace as many old bushes as you can while you've got it apart (ended up @$2200 all up but rebuilt everything including wheel bearings, strut tops) , there's nothing worse than doing a job twice.
Didn't go coil over route as I still wanted standard suspension look as such.
