Z4 Surf 'Rack'

[aten]

Hey Everyone. Just wanted to share the solution I came up with to transport a surf board in a Z4. Board here is 9'.

I designed and built an articulating cross bar that attaches to the roll hoops. It locks into the higher position to raise the rear of the board to be more horizontal and catch less wind (and looks cooler imo). It then locks into a lower position to clear the roof but still allow rear view visibility. I also made pad/strap that uses the roof latch anchors. Both install without modification or damage.

It takes all of 30 seconds to rotate the cross bar and hook on the front pad. I've used it for about a two years now and have gone through a few iterations with minor improvements. Haven't had any issues even cruising at 80 mph.

The material I 3D printed with (PLA) doesn't take heat very well so I do remove it or unload it when im parking in the sun for a while.

I'll try and get some better photos up but here's the gist. Considering making/selling a few of these if anyones interested.

Let me know your thoughts! thanks.

This just reiterated me telling the Mrs on who says it’s not a practical car?

Hi Aten, this is great - I am interested in connecting to discuss getting a rack. Still available?

thanks - topher

Very cool, love to see people fabricate there own solutions to problems.

How much down force does this generate?

Ha. unfortunately it creates a bit of up-force.

Thanks! Yeah still available. I just made another iteration with ABS so no more worrying about heat warping. I'll dm you.

Put the skeg at the rear instead of the front and you'll reduce the up-force. I've always mounted my boards with the skeg/fin at the rear, though never on my Z4.

Hi Aten,

Yes, for some reason I can not DM - something about making a certain number of posts and having to wait 7 days. That said, I did get your PM, though I can not reply to it. If you want to PM your number we can chat. I'm in El Sereno and am happy to meet you - check out the rack, etc... I gotta go West to get to the waves!

I am definitely interested in this 3D print file. Could I get the file.

I would love to get the file. How do we make that happen? Please

The OP has posted here since 2022, so I'm thinking you might be out of luck.
