If your BMW Z3 does not have rollhoops it may be possible to retrofit them into your vehicle. BMW has an upgrade kit that contains the hoops themselves however the hoops can only be retrofitted from into Z3s built on or after 1/97. Specifically 1.9 VIN LB83105 and later; 2.8 VIN LC01377 and later. No earlier production will work.

In addition to the kit you also need to order a replacement set of plastic covers for the rear storage/subwoofer area The cost of the main roll hoop kit is roughly $430 from competitive BMW parts departments that sell over the internet (BMW list price is $640.00). The part number for the main kit is 54-61-9-408-817. The cost of the replacement set of plastic covers varies depending on whether your interior is beige or black, and whether you have the storage compartment or Harmon Kardon subwoofer. See the table below for the additional parts you need and their price. These are the tower covers, side covers for towers, lid for box, small covers where bars go through the lid. With the subwoofer, you will have is the tower covers, side covers for towers, a new lid, and also two brackets and a new subwoofer box.

Please note that the kit for the subwoofer will only work on Z3s with the Harmon Kardon subwoofer. There is not a kit available for Z3s with the "regular" Nokia subwoofer.
