How do using wheel adapters affect the brake rotor/caliper orientation?
I have a set of 17 x 9" ZR-1/SS wheels with 7" BS for my 1967 Firebird 400 coupe; from what I have read I will need a 1.7"-2" spacer to run these wheels. I am in the middle of replacing all my suspension bushings/body mounts, shocks, coils, sway bar, spindles, and wheel bearings right now so I haven't put them on to be able to measure the exact thickness I will need for my car, but the 1.7" front/2" rear adapter seems to be what a large percentage of first-gen F-Bodies are using with these wheels.
How does running this adapter affect the brake rotor and caliper alignment? The brake rotor normally gets sandwiched between the hub and wheel, but the adapter bolts to the hub so does the rotor get sandwiched between the hub and adapter or does it get sandwiched between the adapter and the wheel? I would have to guess the adapter and the hub if the caliper mounting bracket doesn't get spaced off the spindle. . .and using a spacer on the caliper seems like it would introduce a LOT of deflection into the system.
I've never run spacers or adapters before so I'm not sure how the components all work together. . .thanks for the info!
