Ok guys, you're probably not going to believe this but I just got these wheels off a guy on Craigslist for $100! All four for $100. The catch is he didn't know anything about them except they're 5 lug have TSW sticker on the back and "FE71Mandrus" stamped on the back of one of the spokes. Well, I obviously picked them up, cleaned them pretty good and found they are actually made by a company that only makes Mercedes wheels. These are Mandrus Rotec forged wheels, 19x8.5 ET32. As you can see, I mounted one to see how the offset looks and I think they're a pretty sick fit however after multiple measurements and research these aren't 5x114 but rather 5x112. They slid on the lugs just fine but then again the car was on the jack with no weight or lugs.
So, excluding the black plasti-dip which I'll be removing and/or redoing to match the RDX, what do you guys think about the fit? With a 5x112 to 5x114.3 spacer that will add another 1.25" to the already high +32 offset.

 

that seems like a lot more to push the wheel out.

 

Merc wheels?

Be careful, CL is a place to unload shit that is hot, bent or broken. Did you have these checked out? If not, you might have bought four $25 paperweights.

 

Mr Marco, I'm a CL junkie so I'm very cautious when buying and selling. When I picked them up, they were sitting in the guys garage, covered in dust and cobwebs so it they're hot, he stole them quite a bit ago.
I haven't had them checked out but when I cleaned them up visually there aren't any cracks, bends, or welds so the look pretty solid. The wheels look actually to be manufactured by TSW for Mandrus and are quality based on what I've read. Truthfully, I bought them thinking I would just flip them so when I did the test fit and realized I like the +32 offset because I want a flush setup, that's when I came up with the fitment questions.
If they're 5x112 why do they fit on 5x114.3? They slid on with no issue...

 

5x112 fits onto 5x114 because the difference is so small and there's a little leeway with the holes.
However; you'll find that you wont be able to tighten them down all the way because the studs will be off center.
this will prove to be dangerous and will most likely damage suspension components if the wheel comes off while driving.

 

Listed for resale...thanks for the input guys!
