15 inch 4 " (SBP) steel wheels ?

So he just added new holes(by machinist) to get 5x4? Is there enough meat there to do that?
Anyone know of a quality adapter?
yeah, seems like it would be real tight with the BBP 2.82" center register (1/2" diameter bigger than the SBP register)....

are you trying to go from 5x4 on the vehicle to 5x4.5 on the wheel? I've reached out to a machine shop I've worked with about potentially making some that are hub centric for both the car and the wheel, thread is here: Possible SBP to LBP adapter group buy?. I haven't gotten info on how many sets he'd need to make to get them in the $100/pr range yet. I'm a bit surprised at the (lack of and generally negative) response.

my SBP wheels sold faster than I expected, so I was in a bit of a jam, and ended up ordering some off of ebay, this is the listing: 5x4 to 5x114.3 / 5x4.5 US Wheel Adapters 1" Thick 70mm Bore 12x1.5 Lug Studs x 2 | eBay; oddly enough, the listing was $25 cheaper when I bought them a week ago.

note this statement in the description:

"Need something a little different like Studs, Thickness, or Center Bore? We are the Manufacturer, just ask and we can make a listing for you.
If you have any questions, please message us and get the answers before your purchase.
It is your responsibility to ensure that the written description which includes the bolt pattern of the vehicle, bolt pattern of the wheel, center bore and stud / lug nut size are all correct for your application."

I asked them to make the center bore 59mm (to make it hubcentric to the car), and use 1/2"-20 studs, since I already had chrome 1/2" lugnuts purchased to bolt the wheel on, and if they can supply 7/16" lugnuts to bolt to the car, which they all did for the listing price. the lugnuts were nice, bulge style. overall pretty happy, one little nitpick is they put a pretty aggressive chamfer on the backside of the center bore, which, with my axle, made the engagement with the hub not very effective. if you choose to order from them, I'd specify 59mm bore (the 2 5/16" center bore is 58.74mm), 1/2"-20 studs, 7/16" lugnuts, and I'd also specify to keep that chamfer down to like a .040" edge break. they ride great though, and the extra width to the rear changes the whole look of my duster for the better
