The special chassis set is designed to give you a stiffer and stronger chassis for improved handling and durability. Made of stronger, harder and thicker aluminum (7075) and hard anodized. This chassis upgrades the GT2 to MP777 vs the old 7.5 steering geometry for more improvement in handling.
New side guards, steering servo saver, bell cranks and hardware is included for the upgrade.
This is also a good choice for GT1 owners looking to upgrade to GT2 geometry, but remember you will need to update:
Center Drive shafts:
For dog bones use KYOIG101 and KYOMA024
For universals use KYOIFW160 and KYOIFW45
Also you will need a new GT2 body as the wheelbase will be too long for the GT1 bodies.
