Weapon R has seat brackets already for the xb2. So no, you buy the brackets from them, get some rails, and 80% of the aftermarket seats bolt right up. I used the WR seats to showcase it for a photoshoot. I think they sell them for like $300 a set or something. Im returning them on monday, its not hard to install, but it sets of all your airbag lights plus u disable the entire airbag system in your car, not to mention the seats and bracket is lower, so you feel like your sitting on the ground. Its about an inch and half lower. Im 6'3" and with these seats I can barely see over the dash. So yea they look cool, but no.. Id much rather have functioning airbags and a dash thats not lit up like a xmas tree.
