Tamiya 42349 TRF420 Carbon Upper Deck 1.75mm - Performance Club Race Option  [42349]

Dial in Flex for Competitive Handling

The Tamiya 42349 TRF420 Carbon Upper Deck is made to introduce extra chassis flex to the TRF420 platform. Its 1.75mm carbon construction trims the stock thickness, making it a good choice for high-traction setups where added compliance improves line control.

Targeted Flex for Grippy Track Conditions

This upper deck is cut from carbon fiber at 1.75mm, 0.25mm thinner than the kit-supplied deck. The slimmer profile increases chassis flex which can help the car rotate and maintain traction through demanding corners.

Installation and Setup Best Practices

Designed for TRF420 fitment, this deck pairs well with the aluminium lower deck (Item 42350) for a balanced feel. Combine with appropriate spring and damper choices to exploit the additional flex without losing chassis stability.
