Look like your tyres are Achilles ATR Sports? How do you like them? Will probably go with them when I get my new wheels.
My son has those fitted to the sigs on his VY, he says there good in the dry but can be very slippery in the wet when road is only slightly wet, greasy.
He says there ok once all the road grime has washed away or if its bucketing down, they seem to push out the water ok.
He reckons mine on Falken 452s is much more predictable especially in any wet conditions.
We do have different suspension setups, mine is softer with HSV Luxury springs, Koni shocks and big 30/18mm sway bars, his is Kings SL springs, Monroe GT Sports shocks and my old HSV 28/14mm swaybars.
