I got my Bride seats a little earlier than the group buy on here because I ordered them from a different source so some details may be a bit different.
For a complete install you will need:
2 seats (Duh)
2 slider assemblies (which consist of 4 slider mechanisms, 2 handles, 16 bolts, 16 lock washers, and 8 nuts, 8 spacers).
2 model specific seat brackets, with 8 cone shapped spacers ( I got the 98-01 Impreza brackets which worked just fine)
8 more 10mm nuts that were not supplied with the seats
2 one inch spacers can be nuts stack of washers whatever just as long as you can put the bolt through it
2 longer 14mm bolts than stock to use the above mentioned spacers
2 11mm threaded nuts for the factory seatbelts
2 11mm lock washers for above seatbelt nuts
2 3.3 ohm resistors to make sure airbag light does not come on.
1. Lay the seats on their back and unlock the bottoms (like you would to gain rear seat entry into a 2 door car). Then using some serious hand strength push the unlock mechanism down to move the sliders as far down as possible using lock washers install the bolts through the top of the slider one side at a time making sure to use the spacers supplied with the seats between the seats and the sliders. When done with one side top install the handle release onto the two tabs making sure the handle is in the correct position. Install the other side the same way making sure the handle is securely onto the tabs. Then slide the sliders all the way up and install the bottom bolts the same as the tops.
2. The holes in my seat brackets did not line up with the holes on the sliders. Very carefully measure the holes on the sliders and mark on the brackets making very sure they are straight and correct. Using a punch to center the drill bit, drill the right sized holes into the seat brackets. Mine were about one inch (center to center) outside the original holes.
3. Now you should be able to line up the brackets/sliders. Move the sliders so you can install the brackets onto the sliders and put the cone spacers in between the sliders and brackets. If the spacers are not used the bolts will be too long and not allow the seat to move.
4. Remove the stock headrests, and seat bolt covers. Using a 14mm socket unscrew the 4 per seat seat bolts and unplug the seatbelt (driver's side only) plug and the airbag connector (one per seat) to unplug slide the release back and pull apart. Center the the seats so the sliders are in the middle. And carefully remove the seats being carefull not to scratch anything.
5. unbolt the stock seatbelt buckles and install onto the flanges on the seatbrackets using the 11mm thread nut and lock washers. Route the driver's seatbelt wire to the center of the seat.
6. This is the only part I cannot guarntee will work! Install the 3.3 ohm resistors into the stock airbag plugs and tape so they do not fall out. Be carefull not to get the 3.3k ohm resistors like I did they will not work!
7. Install the seats into the car. the inside rear may need to be adjusted (beat with hammer, twisted with pliers) to fit but with a little work it will. The outside rear will need to be shimmed by about one inch and will require a longer bolt than stock.
*note* for the additional nuts/bolts I needed Home Depot did not have them. I work at an Acura dealership and found all I needed in our shop.
