The Kyosho IF473 hard main chassis is a targeted upgrade for MP9 TKI2 owners aiming for firmer handling and better high speed control. The chassis reduces flex under load, which can help drivers hold cleaner lines through turns.
Made to match MP9 TKI2 mounting points, the IF473 provides a more rigid platform than stock options. The reduced chassis movement helps maintain predictable steering and corner entry behavior in race conditions.
Replacing your current main chassis with the IF473 is a direct swap that does not require cutting or relocating parts. After fitting, standard setup tweaks to springs or anti roll bars can help dial in the new balance.
