RCF wheels on an ISF
^^^^Do you mean the stock IS350 4 piston calipers? If so, the ISF wheels wouldn't clear them because they are thicker then the 6 piston ISF Brembo calipers. A small spacer was needed for an ISF wheel to clear the IS350 caliper. That shouldn't be the case with RCF wheels on an IS350. I have RCF wheels on my ISF, and there is much more room between the spokes and the caliper than there was with my old ISF wheels.

So here's probably a dumb question, but what's the best way to determine where my tires are rubbing on the rear? I have rolled the fenders pretty much flat (at least the top section) and I still have some rubbing on the left rear even at stock height. I do have a heavy sub in the back left cubby so I'm pretty sure that's why the drivers side rubs but passenger doesn't.
This is not my first set of aftermarket wheels and tires so simply looking at the fender and liner does not give many clues. Thoughts? Running the rcf wheels with 255/35 & 275/35 combo from the OP.
Side note that the TPMS sensors from the RC will not communicate with the IS.

2) stock RCF wheel/tire size will fit just needs a minor roll on the back (you will see where the sidewall rubs)
3) thanks for the exhaust, still loving it! lol
4) here's mine

^^^^Don't think so. The stock ISF front wheel offset is +45mm, the RSF front wheel offset is +50mm. The change in offset pushes the wheel in .2", But ½ the added wheel width (.5") means the outside rim of the wheel sits .3" further out than the stock ISF wheel.
