As said just get the pro Pistons, they are a different profile and thickness to the kit ones, it's not just about the hole sizes.
Front: number 2 piston, 37.5wt oil, hard spring, 1.2 anti roll bar
Rear: number 2 piston, 32.5wt oil, medium (kit) spring, 1.1mm roll bar
Should be a pretty good place to start
