I have B15 spec V axles and hubs right infront of me and they are 4 lug. Now 4x114, not 4x100. But still 4 lug.
Just take your hubs and rotors to get redrilled for the pattern you want and get new wheel studs. I cant imagine it being more then $25 a wheel + new studs.
Why am I getting deja vu saying this?
