Cheers Guys, i should clarify that i've already got TRX rims on it with new tyres so am pretty keen just to replace the rims, and keep the 15" tyres, superlites are definitely the first choice but spending around $1k on rims i thought i'd see if anyone had something i havent seen before.
After trawling through the hundreds of Datto photos i've got i think its down to 15x6 Superlites for the ute, I looked at the 16x6.5 Concept 5 rims from Tempe Tyres but can't really sway myself that way. I'm looking to grab some this week at around $230 per rim in a chrome lip, dark grey centre from Performance Wheels.
I just thought i would throw this up to see if anyone has some 15 inch rims, no tyres required they're keen to offload before i go and purchase.
