Any 3 door focus from 2005 onwards can be used.
This one is
NOT suitable (mk1 1998-2005)
Also
ONLY 3 DOOR models are suitable
Next is a Mk 2 (2005 - 2008)
This is the first model that is suitable but the doors will not have the correct crease near the top. This can be dealt with in a few ways
1) get the exrtreme modified panels, which they are working on at the moment. These blend the crease out & mean you can use the original earlier doors. Obviously this wont look as accurate as the genuine RS, but if it will be noticable remains to be seen.
2) get a set of doors from a later car that have the crease.
Then 2008 onwards which look like this
and have the crease already.
Headlamps are projector on the RS & the high spec ST's the standard cars dont have the projector, but are exactly the same shape.
The bonnet has to be from a 2008 onwards model. The RS bonnet has air scoops and a lip otherwise it is exactly the same.
All mounting points for the panels and lights are the same for cars after the MK1
Front lights have to be from 2008 onwards. Rear lights will be the same as the donor car as all rear lights were the same from 2005 on.
Rear fog/reversing lights are the same on post 2005 cars and will fit the RS.
Replica alloys are available on the bay of fleas, spacers will only be small so should be able to use either small adaptors or actual spacers provided longer studs are fitted. personally I would put a set of the extreme lamborghini fake brake discs and calipers on but put the RS logo on instead & take it to a ford show!! That would give em something to talk about!! Heheeh!
Badges.....?? Dunno yet, but should be available from ford.
Interiors are very similar, really just need a set of nice aftermarket seats with the RS symbol stiched in.
