http://www.teamcrc.com/crc/modules.p...prodID=7718822 This is the stuff I think we use at S&N's Trackside. The carpet was just replaced last year with new stuff. I think the old stuff was on there for maybe 5-6years. The wear & tear for both foam & rubber seem to be the same to me. Give crc a call & ask some questions. I'm sure they will answer any questions you got.
