How Fat can I go you say?

I wonder if a place like Weldcraft could expand that center hole? I bought the wheels before anything else and displayed one in my office to incentivize me to get off my ***. The BBP forced DB change up front, which spun into tubular A arms, sway bar, 11" shoes out back. Damn those wheels lol.

Depending on what the actual wheel construction looks like any machine shop may be able to open up the center bore some. I had to do that with my Enkei RPF1’s, they start at a 73.1mm bore but taper to a 64mm cap, and the mopar hubs go all the way through the wheel to about even with the outer face, plus the grease cap that sticks out further.

So I had my local machine shop bore them all the way through at 73.1mm. It looks like the YR rallyes are just flat around the center bore, so, they should be able to be opened up some to accommodate for a larger bore. I dunno about all the way out to 3.1” for those Wilwood hubs, but some at least.

I’d just skip the Wilwoods anyway, there’s nothing special about the 4 piston Wilwood calipers and a 3.1” hub diameter eliminates a lot of wheels.
