Aluminium profile rigs generally come packaged as a box of individual aluminium parts, and it is up to you to construct your sim rig. Building an aluminium profile rig does normally take longer than a sim rig which comes with pre-installed parts. However, building an aluminium profile rig doesn’t necessarily need to be hard. Most come with very clear instructions, and the construction methods used are relatively simple. The great thing about aluminium rigs is that you can mount certain parts in a wide range of configurations. This makes 8020 sim rigs very adaptable to a variety of seating positions and mounting positions. If you are not a big fan of DIY, you may want to stay away from 8020 sim rigs, or ask nicely for a friend to help you build it!
