Hey everyone,
Thought I'd share my custom rear rack solution. I never had the intention of buying the Porsche rear rack as I believe the tray style racks that 1up and Thule make are much better since they don't contact the frame and are easier to use than straps. My original plan was to make a cross bar with a receiver hitch so that I could use any hitch mounted rack but decided for a simpler and much lighter solution that's bike specific which is what I use 99% of the time any ways. The other 1% is towing a trailer but I've got an SUV for that.
I machined two extension bars that twist to engage with the slots in the rear mounts the same way the Tequipment rear rack does. Two 1up roof rack trays bolt on to the extension bars and prevent them from rotating out. All in all, the extension bars are about 9lbs total, machined out of 2" aluminum tubing with a calculated load capacity of twice the Porsche rating at nearly 200lbs total and above the actual load rating of the tray racks which are 75lbs each. In use, I would pick the lowest of the ratings and not exceed the 110lb total rating that Porsche has as I'm not sure if the rear mounts on the car are capable of handling more than that. Design wise, for simplicity, it's just a fixed bar and I wanted to keep the bikes as close to the vehicle as possible to reduce the rear overhang. The one piece extension bar also makes it very secure with almost no free play.
Next steps are to anodize the extension bars and add some plastic end caps to finish off the ends of the tubes. Also need to add a license plate mount.
A folding version or something with a quicker release for storage or tail gate access will have to wait until the next iteration. Installed, it just barely fits in my garage.
Feedback welcome. Not planning on selling these but if there's alot of interest, we could get a machine shop to quote a small batch run. Edit: see this group buy thread.
Update 1/27: Dummy trailer plug to deactivate PDC.
Update 2/4: Anodized and fully assembled
Converted to flush mounted trays.
Tailgate clearance for single road bike.
Update 3/16: Cargo tray mounted.
