Kyosho Ultima ST/RB RS3/UM-103 knuckle arm

Kyosho Ultima ST/RB RS3/UM-103 Knuckle Arm. This Part Has Stock Steering/Suspension Geometry. The Part Has Been Reinforced As Much As Possible. It Does Not Use Type-R/EVO Style Collars Between These Parts and C-Hub, Because the Type-R/EVO Style King Pins Are Impossible to Get Nowadays. I Created This Part That Is Both Compatible with Stock Racing Sports Edition C-Hubs and Also Compatible with Type-R/EVO C-Hubs. If You Use RS Style C-Hubs, You Need to Open Up the Upper Hole with 3mm Drill Bit, So the 3mm Shaft Installs Smoothly. If You Use Type-R/EVO Style C-Hubs, the Upper Hole Is Already 2.5mm, So You Can Install the Short Style King Pin Balljoints to It. This Is Also the Reason Why I Ditched the Collars. I Used Kyosho LA235 King Pin Balljoints. For Type-R/EVO Use Without the Original King Pin Balljoints, You Need Shorter Than Stock 3mm Diameter Hinge Pin (Because the Newer Style Upper King Pin Balljoint Is Taking Some Space). If You Have Those Impossible to Find Type-R/EVO Style Long King Pins, Just Drill the Upper 2.5mm Hole to 3mm and Install the Stock -R/EVO King Pins as Usual. So As You Can See, This Part Mixes and Matches to Every ST/RB Edition Parts. Including ST/RB RS/Type-R and Evolution Front Axles.
