Kyosho Mini-Z MR-03 Front Wide Upper Mount Upgrade - MR3-20/BU by 3Racing  [MR3-20/BU]

Front upper mount with increased track offset

This front upper suspension mount is intended for the Kyosho Mini-Z MR-03 chassis and is listed as MR3-20/BU. It offers a wider mounting position for the front upper link compared with the factory MR-03 mount, aimed at drivers wanting more setup options.

Replacing the original MR-03 upper mount lets you change front geometry while keeping the lower suspension layout intact. The extra offset is used to tweak steering precision and front roll distribution for tighter lines around technical sections.

Fitting is straightforward: the part installs into the MR-03 upper mount area using the chassis mounting points. No additional adapters are documented, so inspect your variant for fit and follow standard Mini-Z workshop checks after installation.
