While searching for a possible "track mat" application for the DC2, I cam across these that Rennline makes for Porsches and Minis. I contacted them to see if they would be willing to make a set for the DC2 application, but their resources are tied up for the foreseeable future. Does anyone have something like this that is good quality and works well?

Is the goal for a permanent/fixed mat to protect the carpet/etc during track days?

Yes, basically something that protects the carpet during track days.

I thought PCI offered a similar solution, but I can't find it...
