I am going to transport my MPSC's to the track on the roof. I can't really pull a trailer without hacking my rear bumper (Tech Art GTS) so, here goes.

Here are a couple of views of the rack. It really is quite nice.





As you can see, the mounts never get very close to the car’s exposed surfaces so the chance of doing any damage is really minimal.

I will start framing out the rack with structural aluminum now. At KPV's recommendation, I will be distributing the load over the black vertical mounts as the aluminum cross members are fairly weak.
