I want to know also. Are IS-F brakes in front even harder to clear than the IS350 front brakes?

Here's what comes stock:




So your rear wheels will push out 10mm from stock.

If the front spokes aren't too thick, they should clear the brakes.

Hard to tell from the info you posted, so I think it'd be better to check with 5axis directly. When I inquired about these wheels awhile back, I was told that they didn't have the proper offsets for the F in 20s (Which is strange, but that's what they said.)

Maybe Joe Z knows about front brake clearance with aftermarket wheels on IS-F, since he used to own a IS350............................

I highly doubt they'll clear the rear calipers, especially considering that your wheels are narrower than the stock IS-F rear wheels.

The F rears are 2 piston opposing caliper. The fronts are 6 piston.

Also the problem with the rear IS-F calipers is that they stick out about 1 inch past the hub.
