I just started swapping my blue interior for black interior well I found out the hard way that they are different got the rear in but definately was a full days work with a dremel ....what problems am I going to run into with the dash ?

 

What did you have to use a dremel for? I dropped a full s5 interior into my s4 with zero issues. Dash was exact drop-in replacement, I also swapped my s4 dash support into my s5 dash since it is much lighter.

I've noticed zero differences as far as bolt in for the s4 and s5 interiors, excluding the seatbelt assemblies of course.

 

pretty much identical. the s5 dash has rubber stereo surrounds, witch most likely yours are broken. other than that should be a direct swap

 

cool well I had to dremel the plastic posts on the back of the piece that is overhead (the piece the s4 seat belt bolts into) it stuck out too far and didnt exactly line up and some shaving cause it was set out too far and made a crack where my door seal comes around and looked half ***

 

keep in mind I havent started the dash yet I decided to start at hatch and work my way forward

 

oh by the way anyone has any s4 seatbelts black let me know
