Tamiya M08 On-Road Stiffener M Graphite - Factory Pro O-TCPM01M  [FP-O-TCPM01M]

M08 graphite stiffener for on-road setups

The Factory Pro O-TCPM01M graphite chassis stiffener M is supplied as an aftermarket replacement for the Tamiya M08 chassis and includes the "for 225" compatibility note. Its function is to alter chassis flex characteristics so you can tune handling and steering feedback for paved or smooth surfaces.

Graphite is chosen for its stiffness-to-weight ratio, letting drivers add rigidity without a large mass penalty. In practice, fitting this stiffener shifts how cornering and braking loads are distributed, which can influence traction and turn-in behaviour.

Always verify compatibility using the product name and your kit diagrams before fitting this part. For installation sequence and correct fastener torques, refer to the M08 kit manual to avoid creating unwanted stress elsewhere on the chassis.
