Firstly, I hope that link to the wheels is just to show an example. The 17x8 with a pcd of 5x120 as listed will not fit a Z. Secondly, I would think twice about Wanli tyres ..... read this post from 2005 Spend $6-800 on getting a reasonable set of tyres for stock rims and get alloys later when you can afford them.
Federal 595 are a great tyre Highly recommend them and were used in the Targa Tasmania Rally. http://www.federaltyres.com.au/ss595 Couldn't find a link to a dealer in WA, but ask around, surely someone stocks them. For reference, I paid $170 each for 255/40R 17 on the rears in 2007, still legal tread depth. Car does about 100-150km (hard driving) per week.
Thanks everyone. I bought 4 Kumho's today - $155 each from Tyrepower Port Kennedy. Had to get the lock nuts bashed off as the previous owner lost the key. $35 for new locknuts, and I'm away. http://kumhotyres.businesscatalyst.com/pcrku25.htm
