Todd, if you're using 4KQ hubs... aren't they 4 bolts. Won't work. As for the rotors I have done this conversion on 2 urqs, so you'd think I remember, but I think the V8 urS4 rotors don't work, you need the 200 ones (because of offset issues). It could be the other way around, but I'm pretty sure..... Andrew Finney 1985 UrQ
