anyone out there running a harness / guide bar for AutoX?

I've seen them at AutoPower and IO Port Racing.

I don't want hack up my interior, but I want to have good harness angles.

 

I'm not running a guide bar but we just installed the new Schroth ASM 4 for the MINI. It goes in with two anchors (into existing mount points). The nice thing is that the two anchors have buckles on them to snap in the left two points of the harness (rear mount and left side) and the other side buckle directly into the existing rear seat belt buckle while the front buckles into the driver's side buckle. It creates a nice X harness angle in the back, doesn't ride up on your waist and can pulled completely out of the car when not in use. I'll be posting a how-to of the install soon. I purchased mine from MINI Motorsport. Hope this helps.
