I changed my door inserts to carbon fiber silver. looks pretty nice. i don't think that you would want to use suede or a material that is heavy. it would fall in no time. i will ask my brotherin law this evening he has an upholstry shop. you could check out my interior on my homepage. we used the carbon fiber and a vinyl called ellante in the package tray. and we are using both in the trunk but with custom enclosure but the trunk is not done yet. I also did the seats with blue and black leather with chrome embroidery with silver stitching it looks awesome, and with the seat heaters toasty
