EVO-R conversion chassis set

This is a conversion chassis set compatible with (GRKGS2E) GRK GS2 EVO and (GS2MOD) GRK GS2 Modified (*see note 1).

Developed as the first motor layout model inspired by the GRK4/5 within the GRK Global Series lineup, this chassis set takes GRK’s renowned balance of rigidity and precision to the next level.

The 2.5mm main chassis and 3mm upper deck are made from the same high-performance carbon material used in the GRK5R HRP model, which claimed victory at the 2025 SDC Championship in the U.S.

While maintaining compatibility with the standard mechanical layout, the design has been optimized for today’s RWD drift scene, achieving the ideal balance between roll rigidity and lightweight performance.

※1 This is an advanced model that requires customization such as changing the gear adapter and other adjustments to fit your existing chassis setup.
