I have a very interesting (slightly irritating) finding. The top inserts (for diff front mount, ie see pic below) of the whiteline KDT925 (https://www.whiteline.com.au/product_detail4.php?part_number=KDT925) does NOT fit my stock GR86 bushing. Somehow the OD of the stock bushing is smaller than the ID of the concave side of the top whiteline inserts. iirc these top inserts supposed to be fitting tightly to the stock bushings and at times irritating to install cos they "pop out" while raising the diff and tightening up the bolts. Instead they are really loose with these gr86 stock bushings.
The bottom inserts and the diff rear bushing inserts all work perfectly.
But i guess the good thing is, with all the inserts (sans the aforementioned front mount top insert) mounted, there is ZERO NVH increase! And (maybe placebo but whatever) car feels more responsive esp with hard tip in of gas pedal in2nd and 3rd gear).
