Front seats
OK, the fun part First off remove the mk3 seats which is pretty straight forward, slide them all the
way forward, remove the track guard from the outter track, then slide them back and remove the small pin
holding the seat adjuster in place, then once this is out the whole seat can be pulled back and out of
the tracks and removed from the car.
Once removed you will see the post where the adjuster was mounted to. This is all that needs to be
modified within the car. I used a hacksaw as I burned out my grinder on my boost piping Its not too
bad though there isnt much cutting to do. What you want to do is cut most of it down and just leave
enough at the front to drill in 2 holes for the mk4 adjuster. Its a very similar design to the mk3 seats
it just mounts differently at this point
Unmodded mount
Firstly I cut along the sides as shown, then bent and pulled off tops with pliers
Then cut the rest of the uneeded metal as follows until you are left with just the 2 tabs at the front
As a bonus you may find as much crap as me under the seat! Heres a pic of the pin that needs removing from the mk3 seat along with all the stuff I found under the carpet. I actually found 2 pound coins but I used one to buy a sausage roll for lunch :grin:
Now onto the mk4 seats. Not much needs doing here really, the wheels need cutting a bit to make them a
tad slimmer and some bits and pieces need removing.
First off the wheels. You need a m10 spline to undo the nut holding on all these bits, once off you can
remove the wheel and the spring with the guide thing on it. The spring can be binned but keep the wheel,
what I did was cut one side down so it was flush with the middle. I also filed a smalled amount off the
outsides.
Remove these and bin them
You want to be left with something like this
You need to do this for all 4 wheels, when you put them back on it might help you to not tighten the
spline nut all the way on the outter sides so the wheel can be pulled out a bit further than if it was
tight. You can put washers in there once you get the right position so the nut can be tight again. No
pics of this but I hope its understandable, this part isnt compulsory but it makes the seats much easier
to slide forward and back
Last bit of modification needed is on the metal piece that bolts on with the seatbelt adjuster.
Its shaped in a way so it can catch on the groves in the mk4 seat runners, but I can only assume the
mk3 runners are a different design as this isnt neccessary and all it seems to do is make it almost
impossible to adjust the seats. What I did here was undo the bolt holding on the seatbelt buckle and the
pain in the arse metal piece, and grind down (by hand!) the pointed bit so its round and slides easily
in the runners. Annoyingly you cant just spin it round so the point angles differently as the way the
buckle fits on it has to be pointing towards the grooves
This is pretty much you finished now, try the seats in the runners and see how easily they slide. Some
grease may be needed to make it smooth but I didnt need any in mine. Once all the minor adjustments have
been made and they are sliding ok you can get the runner lined up with the mounting point and mark where
the holes need to be drilled. You should end up with something like this
When I did mine I did the wheels and runners first so I could eye up how much needed to be cut off the
old mk3 mount and get it just right
Now bolt everything in clean up the mess and admire your new mk4 interior
