This original Tamiya part does a great job to my TT-01 steering. The handling of the car has become much more better. I'm recommending this product to everyone who wants a lot better steering to your RC-Car.
I installed this hop-up on my tt-01D. When I test it especially drifting, my steering response improved drastically. This item is a must for precision steering for touring and drift.
Upgrading to this steering set makes all steering movements in the chassis much smoother and more precise. The blue anodized aluminium looks great on any chassis, and the gold screws also look awesome!
