hey guy just had a quick question...
will a s5 door fit on a s4 car. i recently picked up a door to replace my door which is damaged. i got a s5 door and the one i am removing is an s4. just want to know id it will fit properly and will the electrical still work...
also this door looks to be missing a clip of some sort... will this be a future problem???

 

I don't see why the doors should differ in any way, besides the width of the trim on the door skin. If you're concerned about the wires, just pull the harness out of your bad door and swap it into the new door. Done.

 

I ended up putting an S4 door on my S5. The only problem is that the S4 door didn't have a sensor in it for the auto seatbelt. Not really that big of a deal in my opinion. Also, I think the sensor for the alarm is different as well. But other than that they will physically fit.
