Hi ya guys

As promised a guide on how to modify your seat runners to go all the way back giving that extra bit of leg room, I did this yesterday and it really does give you a load more leg room.

1. Remove seat from the car, there are 4 bolts that hold the seat to the car and 1 that holds the seatbelt runner to the car. These are all 14mm iirc.

2 Flip seat fowards as if you were letting someone get into the back of the car as this allows it to come out easier tip it up and there will be 1 electrical connector from the car to the underside of the seat undo that then take the seat out very carefully.

3 Place the seat on the ground with the rails facing up (img 1)



4 The way to get the seat to move further back is by drilling out the dimple and the rivit on both sides at the back that act as an end stop. (img2) The red lines on the picture show these.



Here is a close up the rivit is the one being pointed to and the dimple is the one above it.

5. You will then need to grind the rivvet flat in order to drill through the rails.



6. Now drill out the dimple above the rivvet that you have ground flat, I did this starting with a small dril bit working my way up to a monster sized dril bit, you need to keep increasing the size till you have totally removed the dimple. This is also going to be the same size as you will need for the 2nd hole.

7. I then created a template out of wood as I couldn\'t template out of wood so I could be sure that I was drilling through where the rivvet was as I couldn\'t find my centre punch.



8. After then using the same process of increasing the drill size till I had removed all trace of the rivvet I have 2 near holes that will allow the seat rail to slide past its end stops.

 

9. Give the rails a good slide and make sure they clear the holes you have just drilled if not you may need to encrease the drill size or get a file out and tidy up the holes.

10. Refit into the car the same way as you removed them and marvel at the fact that you can\'t drive now the pedals are in a diffrent place.

Sorry to bring up this old thread.
I have a japanese import fd and is it true that rails from uk FD\'s go futher back?
The drivers side is good but on the passenger side it looks like it can go allot further backwords.But it wont.
And do they go as far as the modyfied one\'s?

Thanks :chat
