As subject I am may be purchasing some Recaro front seats out of another factory car. The only problem is they are from a 5 door car and come with their own runners. (Hopefully I'll be able to modify the bases to fit though?) Anyway I was just wondering how you would normally go about fitting aftermarker seats? Will the new subframe with the seat also use the existing seat belt clip? Also what about the air bags in the seats? How will the system function without these? Cheers Mark.
