KT Back Wing 0 and Positive Shim Set
The KT Rear Wing 0 and Positive Angle Shim Set is an adjustment accessory for the stabilizer or rear wing (tail wing) of KT foils. These 0° and positive shims increase the positive angle of attack of the rear wing, which generally increases pressure on the front foot, improves stability, adds more lift to the nose, and makes the foil feel more “locked in” and predictable.
They are ideal when using larger front wings, shorter masts, or when you feel the foil has too much “nose dive”, insufficient front foot pressure, or feels unstable.
The pack includes 5 positive shims with different angles: 0.0° / +0.5° / +1.0° / +1.5° / +2.0°.
These shims are placed between the fuselage and the tail wing. To find the ideal shim for your KT foil, use this simple formula: Front Wing Value + Mast Value = Recommended Shim.
Each front wing has a number printed on it (e.g.: -1, 0, +1, etc.) and each mast also has a printed value (e.g.: -0.5, 0, +0.5, +1, etc.). Add these two numbers together and the result tells you exactly which shim to use.
Practical examples:
- Front Wing Atlas 790 → value -1 & 85 cm mast → value +0.5 → -1 + 0.5 = -0.5 → Use -0.5° shim
- Front Wing Nomad 980 → value 0 & 77 cm mast → value 0 → 0 + 0 = 0 → Use 0.0° shim
- Front Wing Atlas 1130 (large) → value +1 & short mast → value -0.5 → +1 - 0.5 = +0.5 → Use +0.5° shim
