if anyone is still reading this 9yr old thread, i'm going through exactly this same problem. spoke to dexter; no luck. tried different lug nuts; no luck. SOLUTION: Rough Country makes adapter rings that will fit the imperial hub sutds and provide the metric studs needed to support the 4runner's alloy rims. i've spoke to quite a few guys I'd consider experts on this specific topic. This is the only solution that will reliably work without having to worry about snapping studs.
