Fliteboard Negative Shims – Fine-Tune Your eFoil Performance

The Fliteboard Negative Shim Set allows riders to precisely adjust the pitch and balance of their Fliteboard eFoil setup. By installing different shim angles between the foil components, you can fine-tune the ride feel, stance position, and overall performance of your hydrofoil.

This set includes five front wing shims and five stabilizer shims, designed to help riders achieve a more balanced riding position and improved control on the water.

Negative shims are commonly used by riders who want to reduce nose-up pitch and shift their stance slightly back over the mast, resulting in a more comfortable and efficient riding position.

Why Use Negative Shims on a Fliteboard?

Hydrofoil shims are one of the easiest ways to customize the feel of your eFoil. Adjusting shim angles changes the relationship between the front wing and stabilizer, which directly affects lift, pitch stability, and rider stance.

Using negative shims can help you:

• Achieve a more level board pitch

• Reduce excessive rear-foot pressure

• Improve control and stability

• Fine-tune your foil for different riders and conditions

• Dial in performance for speed, glide, or surf riding

Many riders find that small shim adjustments can dramatically improve comfort and efficiency during longer eFoil sessions.

What’s Included

This shim kit includes:

Front Wing Shims

Rear Stabilizer Shims

These graduated shim angles allow riders to experiment with small changes to achieve their ideal foil setup.

Note: Some thicker shim combinations may require longer bolts.

Who These Fliteboard Shims Are For

These shims are ideal for:

• Riders who want to fine-tune their Fliteboard performance

• Lightweight riders who want a more balanced stance

• Advanced riders dialing in speed or efficiency

• Anyone experimenting with different wing setups

Even small adjustments to foil angles can noticeably change how the board rides.

How Shims Improve eFoil Performance

Hydrofoil shims adjust the angle of incidence between foil components, allowing riders to tune lift and stability without changing wings. This lets riders customize their setup based on weight, riding style, and water conditions.

For example:

• More negative shim angle → faster top speeds and a looser ride feel

• Less negative shim angle → more lift and stability

This makes shim tuning one of the most effective ways to optimize an eFoil setup.

Frequently Asked Questions

What do Fliteboard shims do?

Fliteboard shims change the angle of the hydrofoil stabilizer or front wing, which alters lift, pitch balance, and the feel of the board while riding.

Why would you use negative shims?

Negative shims help reduce nose-up pitch and allow riders to stand farther back on the board for improved comfort and control.

Are these compatible with all Fliteboards?

These shims are designed specifically for Fliteboard foil systems and are intended to work with the standard wing and stabilizer interfaces.

Do shims change speed?

Yes. Changing the foil angle can affect drag and lift, which may increase efficiency and improve top speed depending on the setup.
