I'm researching doing a vented front brake swap onto my '81, and finding that whether it'll need spacers depends on what wheels I have. I've got two 1st-gens here, both '81 4x4 longbeds, with two different aftermarket wheels, neither of which I know the name of. The "swirly" cast aluminum ones have substantially more clearance with the brake calipers than the stamped steel. I bet they'll clear vented-rotor calipers without spacers, but I'm not sure.

What wheels are known to clear later (vented rotor) calipers without spacers?

Maybe this could be a survey for those who've done a vented brake swap (or know the technicals of someone else's). Please post...

1. Your calipers and rotors (for example, '91 4Runner V6 calipers, '81 Landcruiser rotors).
2. Your wheels (f.e. Cragar Whatchamacallits, 15x8, 4" backspacing)
3. Your spacer thickness and position (f.e. 3/4", normal position between hub face and back of wheel). Please note if you have more spacing than strictly necessary for brake clearance.
(4. optional) Other particulars, like if you're running non-stock hubs, or modified caliper mounts, or...

Here are my two sets of rims. Can anyone tell me what these are?
