I ordered a set of 17x9+24 Saleen replica rims for my Sport and they look awesome! Too bad they don't fit over the front rotor/hub... It looks like it's the outermost section of the 2WD rotor that's just barely hitting a lip on the wheel where the center cap snaps in. The lip could be machined down, or a thin spacer would stop the rotor/hub from reaching the lip in the wheel center bore.
I'm going to try 1/4" spacers which I'm pretty sure will eliminate the rotor interference, but from my measurements, I still don't think that'll be enough to clear the upper ball joint if I go with 275/55 tires. The 0.25" spacer/24mm offset/9" rim width/275mm tire calculation I did suggests the setup will come inboard 30.4 mm compared to stock 235 tires and I only have 33mm between the 235 tire and ball joint now -- 3mm is well within my expectations for tire flex so it's probably a no-go. I do think 255/60R17s would fit fine with the+24 offset, but I'd really like to go wider.
I'm looking at longer studs and hub-centric spacers because bringing the wheel out another 1/4" (beyond the 1/4" I already mentioned) will have me back at the factory offset and give me a safer amount of tire/ball joint clearance. From what I've read, slip on spacers are safe as long as they fit properly around the hub instead of relying solely on the lug studs for alignment. Does anyone have a recommendation for wheel spacers? There aren't may I can find with the proper center bore. These are the best I've seen:

Also, does anyone know the factory lug stud knurl diameter? I contacted PowerStop for the lug stud specs for the studs in my drilled/slotted '01 Sport rotors, and they just said "same as OEM" ...ugh. I see 0.550", 0.565", 0.570", .610", 0.618", 0.619", 0.620", 0.627", 0.628" knurl diameters all are listed on Summit as being "for my 2000 Ford Explorer" but I know well enough that a few thou might as well be a mile when you're talking press fits.
