    that's the pretty good deal. i would buy them just for the look because i don't track my car and the stock brake look small on my 19s.

Since your offset is even more extreme I'd think you'd be okay (might be tight tho). My wheels would be really really close tho (not that I have $ for brakes).
    offset normally shouldn't effect caliper clearance. the only way it would, is if spoke design changed between one offset and the next.

    offset should really only effect strut clearance.

    False, as we are talking about barrel clearance and not spoke clearance. A number of wheels have tapered barrels that get larger toward in "inside", therefor offset will effect clearance.

    [edit]: Offset is also the main factor in spoke clearance, BTW.

    are you referring to the hub as "the barrel"?

    i don't know where you draw your conclusions from, but spoke design actually remains fairly identical across a broad variety of sizes in many designs. the key difference being the rim actually being "slid" inboard or outboard relative to the spokes/hub. this is especially the case on 2-piece wheels.

    again, offset primarly effects strut clearance/flushness to fender. any effect on caliper clearance is a byproduct of changes in/to spoke design between sizes.

    Okay follow along. Two otherwise identical wheels have a slightly tapered ID (smallest ID at wheel face, largest ID at wheel center). One wheel is "offset" more than the other. The radial rotor/caliper clearance will be slightly greater on one wheel because the caliper is closer to the wheel center on the more "offset" wheel.

    fucking 3sgto decided to crash after i'd typed out a resonse.

    bottom line, there's only 2 ways to effect caliper clearance. change spoke design, or increase/decrease thickness of center hub. on any given size (just different offsets) neither one of these is the preferred method of manufacturers. instead, MFG's treat the hub & spoke as a solid unit, and modify where the spokes attach to the RIM...to generate the offset. even between sizes (18x8.5 - 18x9.5) this still remains largely the case.

    OK, I'll explain one more time before I go ballistic with the delete posts key.

    We are talking about the clearance from the brake caliper OD to the wheel barrel ID, which is the ID of the wheel, you know, the part that connects the 2 beads of the tire.......


    WE ARE NOT TALKING ABOUT CLEARANCE FROM CALIPER TO SPOKES


    Don't make me draw a damn MSPaint diagram.

    you mean to the inner edge of the rim. that's a much simpler term.

    Simpler doesn't matter when there's a correct term for that part of the wheel. "Inner edge" is the inner bead area, where it would interfere with the strut, the entire "ring" as a whole is called the barrel.
