Re-drilling your Hubs is dangerous, i have pictures of hubs that have been redrilled and you loose 2 out of 6 brake rotor mounting bolts and 2 other mounting bolt threaded holes have a wall thickness of under 0.050"....
The Cheapest way to convert is to do the toyota conversion, or if enough people get together and bug me about mazda conversion i'll build a production run of my 5 bolts hubs with big brakes... if i get 5 people that are willing to pay up front for the bolt on conversions i will build a run of parts....
