I don't know if this has been addressed in this thread, but....
The only place I know that still does torque thrust style wheels in 5 on 4, is ET mags/Team III Wheels. Available in various sizes and backspaces... but NOT cheap (starting at about $500/wheel). All in all, not TOO bad for a custom wheel.
Boyd Coddington used to make a 17x7 and 17x8 version in small pattern, at about half that price, but I don't know if they are still available.
