Are all these pictures from a g35x? The door panels are different than the regular coupes. Is the material flexible enough to fit the sharp curve of the leather here?

 

Sedan and coupe doors are completely different. X and regular sedan doors are the same.

 

Thanks for taking the time to post this, turned out great especially with that interior color scheme!

I have the same issue on my 03, and will tackle this in the summer months.
I have the wood trim which i am not really a fan of, so i might recover them with while i fix the upholstery - maybe carbon fiber vinyl or something, trying not to make it look cheap/tacky

 

Was this the same product as the original poster? Please let me know.

 

Similar if not the same. It comes in many colors. It’s just automotive upholstery piping. You won’t find much variation or size differences.

 

Did mine this weekend. Thanks to OP and all others that contributed to this thread. Tried to upload pics but they kept stopping in the upload process at 90%

 

I'm glad this has been able to help so many people!!

 

Here is my before and after

 

I really like the silver/gray color choice for your piping. It looks great!

 

Looks great!! Exactly how mine looks!! Amazing job!!

 

An update to mine, I am surprised how well it is holding up. The installation of the piping is not within any wear area where I grab the door or rest my arms. Considering this I probably used too much glue when I installed mine. A little dab here and there should work, don't need to try a thing continuous bead. The piping almost has enough friction to hold itself between the door card and door foam padding, so test fit completely before adding glue. Super glue can be the enemy because it may try to stain the door card or melt the foam backing.

 

Was in a shop getting my standard driver's side seat tear fixed and decided to get these panels swapped out as well. I like that it adds a pop of color to the backseat, didn't realize how monochrome it was back there before.
