Mounts, clamps, shaft extensions and power upgrades for the wheel base in your build.
Most wheel base accessories are brand specific: a mounting bracket or quick release adapter made for one base rarely fits another. With a wheel base in your build, this page shows accessories from the same brand by default.
Common upgrades include desk or cockpit mounts, shaft extensions for a better wheel position, and boost kits or power supplies that unlock a base's full torque.
Expect €30–€80 for a mount or shaft extension, and up to €200 for a boost kit or upgraded power supply on a high-torque base. A boost kit is only worth buying if your base is rated to use the extra power, so check the base's own spec page first.
