Its just as easy swapping the runners too? If not easier?
The whole thing is just four nuts a seat. One in each corner. Undo from underneath the car.
Removing the runners you have to undo more nuts, remove plastic covers, and risk damaging the seat position sensor on the drivers side.
If you get them, get Ph2 172/182 Seats. These are essentially the same, just different coloured dots on the seat material.
Ph1 172 are slightly different colour. Not as nice imo. Airbag connections should be the same if you get ph2 172 or 182 ones too.
I've literally just made a guide regarding airbag wiring in the guides section too!
