style 5's are definitely top 3 oem wheels for e34
Try craigslist for used sets if your not into paying an arm and a leg for them at the dealership... I just picked up a complete set of Staggered 17s Style 32's for less than the replacement cost of only one from the dealers
good luck on your hunt...
I will be running hubcentric rings as well since my set was off an e39
