3Racing Sakura M4 SAK-M4S39 Lightweight Fiber Upper Deck  [SAK-M4S39]

Improve Chassis Response on the Sakura M4

The 3Racing Sakura M4 Fiber Upper Deck, model SAK-M4S39, is intended to strengthen your Sakura M4 chassis where it matters most. Constructed from quality fiber material, it reduces flex under load and helps the car track more predictably through a sequence of turns.

Track-Oriented Advantages

By increasing torsional stiffness, this upper deck sharpens steering feedback and reduces mid-corner wallow. Its minimal weight keeps the car nimble, so drivers retain precise control when making small setup changes.

Designed for Direct Fitment

Made specifically for the 3Racing Sakura M4 range, the SAK-M4S39 is a direct-fit part that integrates with the stock chassis layout. No exotic tools are needed for fitting, so you can install and test on the same day.
