The only place you are realistically going to be able to get the wheels for a decent price is Yahoo Auctions / Trademe. 14s or 15s are best and most old school wheels only come in 13-15 anyway.
You will not get the dish in your picture without either having flares or modifying your suspension significantly. The lower the offset the better which means the closer to 0 or a negative number, the more dish. Some cars will take a 0 offset without mods, unsure on 1600 but using the rear camber will be necessary. Look at my thread and you will see my wheels. I think the front are +12 offset and rears are +6 from memory?
Be aware that buying some of these wheels new is possible (where you will be able to pick offset) BUT price is hurrendous
Expect to pay no less than $3500+ for just wheels, not including shipping which whill be at least another 500-1000.
There is one dude in NZ who is the "NZ Distributor" for Work/Volk/Rays wheels but he is a rip off (expect 4000 for wheels) and hopeless to deal with. Trust me I have tried many times when I managed Mag and Turbo in Wellington.
Second hand on Yahoo Japan is the best option although heaps of other people are onto this method. 5 years ago, dirt cheap, heaps of options. Now days where everyone has the same idea, the really good condition wheels with the micky offsets go for large prices and get snapped up quick. You have to pretty much search every couple of days and you will still need an agent (that can speak Japanese) to buy them on your behalf. I have used Ewan from

Still expect to pay around $1500-2000 landed for an average set. You dont want them with tyres or will cost you way more in freight due to weight. You will also get stung with having to pay duty/taxes when they land because the value is over $500 NZD. so thats another 12.5% at least of their value you will have to pay to customs. Me and a couple others have been lucky, mine came in the boot of a car that was imported and another mate who lives in Japan brought them with him when he returned to NZ therefore avoiding the tax.
If I didnt already have my SSRs I would look on trademe, cheaper and still nice wheels come up. Here are some Work Equip 01s -

My 5 cents.
