Short answer - NO. Long answer follows.

Some things to keep in mind re the 850 wheels. First, the '93's (and some early 94's)used a 4-bolt pattern. Second, neither the 4-bolt (obviously) nor the 5-bolt pattern will bolt up directly to the 200/700/900 series RWD bricks. Lastly, the wheel is designed for FWD so there is significant offset which differs from that of the RWD cars.

Of course as we say in da bidness, there is no engineering problem which cannot be solved by brute force and ignorance. The cure in this case is *wheel adapters* - specially machined adapters which bolt up to the RWD lugsm but which accommodate the 5-hole FWD wheels and their bolts. The "brute force" in this case is money - these rascals are pricey, aroung $250 for a set of 4. I can't recall a source offhand, but do a google search on 'volvo wheel adapters' and you will find at least 2 sources. What makes them expensive is that GOOD aluminum has to be used for strength, and the fact that the wheels are "hub-centric" which means that the bolt circle and the center hold need to be pretty precisely machined. In my world (aerospace) the tolerances are no big deal, but don't expect your brother in law with a ShopSmith lathe in the garage to knock 'em out for you for cheap. Given the cost of material and the machining work involved, $250 seems fair to me. Now if you can get a set of 850 5-bolt wheels and centers for, say, $200 or so, then get the adapters and you'll have a great-looking set of wheels! With a '97 855 in the driveway along with a 245 and a 244, I can easily envision the Cetus (6-spoke) wheel on either RWD beast... I think they would look great, and the 6.5" width would be a nice asset with 205 width tires. Just need the $ for the adapters!
