As in topic... what do i need to do to convert my car to 5 lug and what does "unilug" mean? Thanks

I'll let someone else answer the 5 lug swap question, but Uni-Lug wheels have reversible washers that allow for the wheel to fit two different bolt patterns. My Torq Thrusts are Uni-Lug, and will fit both Chevys and Fords.
