Live to race!
The RM-01X features a number of parts designed to boost the chassis' racing prowess. The chassis features excellent durability thanks to numerous aluminum parts and carbon components such as the lower deck, lower brace and damper mount. Aluminum pitch and roll dampers are fitted as standard, and by changing damper oil and grease viscosities drivers can make precise adjustments to suspension performance. To bring out the best in the suspension, the kit includes carbon-reinforced front suspension arms. Not only that, but the ground clearance is adjustable using the kit-included spacers. This chassis really puts the driver in control.

The Direct-Drive 2WD RM-01 chassis is a 1/12 race car platform that features independent coil spring suspension and a PBLR (Pillow-Ball-Rear-Link) suspension. The platform is ideal for 1/12 club racing for both carpet and asphalt race tracks. Previously released as a basic assembly kit with iconic race car bodies such as the Toyota Tom's 84-C, Porsche 956 and Mazda 787-B, the RM-01X is a special "limited edition" race kit which includes a huge selection of the Hop-Up-Options available for the platform. The parts included bring out its maximum performance at the track. FRP parts are replaced with carbon parts to enhance chassis overall rigidity, and an aluminum motor mount offers increased motor attachment rigidity for optimum power transmission. Furthermore, carbon reinforced front suspension arms provide optimized suspension effect.
