You can start with a basic rig, then acquire additional add-ons and accessories later. The highly adjustable design of the PSR1 Rig allows you to assemble the product to fit your individual needs. The PSR1 Rig can be adjusted more or less on every aspect both horizontally as well as vertically.
The PSR1 Rig has 3 versions: High, Medium, and Low.  The difference being how high the seat is mounted, in comparison to the height of the pedals.
Low version: Seat low, pedals high. This simulates the feeling of driving a formula car.

The low- or medium version can always be changed to a high version with an additional upgrade kit.
