Coming for the exceptional Mi9 Chassis is this TITC Spec Top Deck.

This 2mm one-piece top deck, used by Michal Orlowski to win the prestigious TITC race in Thailand, is perfect for tuning your Mi9. It's especially effective on high grip, high speed tracks with long corners. In general it can make your car stiffer overall. The rear bulkhead brace keeps the rear end stiff and locked in, providing a smooth, stable driving experience.
