I too like 16's for the and room for larger brakes and chioce of tyres with reasonable rolling diameter .
Late last year I purchased via Craig at Traction a set of 16X7 Rims called Sirrocco out of Speedy Wheels Sydney. They are still listed at ET38 and come blank so can be drilled ( by Speedy) to suit the required stud pattern. Cost was about $270 each at the time I think. See
http://www.speedywheels.com.au/alloy.htm . They are cast and obviuosly heavier than say a Simmons but I am happy with them Cheers Eddy
