you can buy 4 to 5 lug bolt on adaptors, but I recommend going the right way and converting your 4 lug VR4 to 5 lug. This can be done using front wheel hubs and rotors off a talon, eagle, laser. In the rear you can do the same or swap the whole subframe which directly bolts in, although will require additional work to remove or keep your all wheel steering. Or you can swap the 1g trailing arms with the whole rear hub assembly as swapping just the hubs in rear is a much bigger pain in the ass. Good luck.
