Just a comment about the Toyota 4x4 vented setup, on my past set of Rota 16x8" wheels I DID have clearance issues. The issue spawned from the brake literally being too small, so the caliper was too close to the center of the hub where the meat of the wheel is. I decided to upgrade to 12.2" brakes, alternatively, a small (5-8mm) spacer would have corrected the problem or I could have ground down the extra iron on the calipers, or the aluminum of the wheel.
As for these wheels clearing stock springs. I would think that they should. Check post #60 image 4. There was 5/8"-3/4" of clearance between the mock wheel and my coil over spring perch. The coil over perch is ~3.5" OD. If you could measure your spring perch OD that would be appreciated. This setup should clear a 4.75"-5" OD spring perch.
