Is it the CF Adjustable version? (Mugen style?)
Or is it an OEM style CF version?
If it's the former - you lose the brake light, unless you can re-locate it somehow.
If it's the latter - you should have it integrated into the spoiler anyway, whereby, it'd be a straight swap - and a case of re-clipping the brake light connector in.
To fit it, all you have to do is remove the upper boot trim - there will be 6-8 bolts - just undo those and swap the spoilers over, and rebolt them up. The adjustable wing has less bolts than the OEM wing. HTH.
