Thanks Glenn, had the suspension fitted on Friday (at East Coast Customs), just in time for a test at Lakeside on Sunday
. Due to traffic and other events, not much space/time for a full test, but it certainly did make a noticeable difference in handling (almost zero body roll, much reduced squatting under power and nosediving under braking) and no noticeable decrease in comfort.
Question to follow on then. Conflicting reports suggest the Aussie Mustangs (with the performance pack) already have uprated sway bars from the factory, so are they the same as the Ford Performance uprated sways available or not? That's the next thing to do for me before I start messing with a tune.
