Ah nice. Look forward to seeing that.
Phil did my carbon roof on my 3dr Sierra. Never did see the windscreen pillar panels tho..
I don't know how strong the carbon versions will be compared to grp, but be v careful after fitting it as the oem struts are way too powerful for the weight of the boot lid (esp if you're using poly-carb screen) and its really easy to rip your hinges right out of your new bootlid.
Make sure you post plenty of pics when it arrives.
Cheers
