The Roadster doors are very long and the hinges weren't particularly well designed to deal
with the weight and length of the door. Couple this with the fact that many people seem to
use the doors as an aid to get in and out of the car, this puts extra weight on the hinges.
The doors slowly creep down over the years until they don't quite seal
against the seal properly, then you get water ingress and wet speakers.
It's a fairly simple fit, we just need to loosen the bolts holding
the hinges to the door, lift it and tighten them up again.
You can see quite clearly that the glass isn't sitting in the optimum place on the seal.
Remove the 2 Torx screws inside the door shut, the Torx screws running along the top of the wing, the headlight cover and headlights, the single Torx screw where the arch meets the side skirt and the 2 plastic rivets that are in the back of the wheel arch. You can now pull the arch panel away.
Remove the 4 Torx screws that hold the cover in place. Make sure the door is closed now.
Slacken the 3 Torx bolts by half a turn with an E12 socket.
Lift the furthest edge of the door up the highest it will go, let it down about 5mm
and tighten all of the Torx bolts with one hand whilst holding the door with the other.
Check how the door sits against the seals.
It may take more than 1 attempt but it's not hard. The slam/striker plate on the rear
edge of the door should pass directly in between the catch opening, if you align the
door perfectly and the sticker plate touches, you will need to adjust this too.
As the door sags it can drag the striker plate down or wear it. This is when you start getting the door opening by its self as you drive. Just loosen the striker plate bolts and move the plate before retightening. Do not remove the bolts altogether or the nuts will fall down into the bodywork.
