Asetek SimSports Initium THORP II Upgrade Kit

Hydraulic Precision. Real Race Feel. Absolute Control.

The Asetek SimSports Initium THORP II Upgrade Kit brings true motorsport-grade hydraulic braking to your simulator.
Featuring the Twin-Hydraulic Opposing Rapid Pistons (T.H.O.R.P. II) system and an automotive-grade pressure sensor, it delivers a realistic dual-stage brake response — soft, progressive travel that transitions into a solid, high-pressure stop, just like a real race car.

Key Features

• Twin-Hydraulic Opposing Rapid Pistons (T.H.O.R.P. II) for authentic brake feel

• Automotive pressure sensor for ultra-precise, realistic force feedback

• Dual-stage braking response – “Soft Stage” for modulation, “Hard Stage” for lockup realism

• Supports up to 100 bar of hydraulic pressure (~185 kg pedal force)

• Plug & Play installation – compatible with all Asetek Initium Pedal Sets

Race-Car Braking Feel in Every Corner

The T.H.O.R.P. II system perfectly simulates the mechanical dynamics of a real racing brake pedal.
The Soft Stage offers smooth, progressive travel that mimics pad compression and hydraulic buildup, while the Hard Stage provides a firm, immovable brake wall — giving you absolute precision when braking on the limit.

Trail Braking Mastery

With its true hydraulic pressure curve, the THORP II upgrade enables accurate brake modulation and pressure sensitivity.
You’ll feel the difference when controlling weight transfer through corners — exactly how professional drivers manage their braking inputs on track.

Realistic Lock-Up Feedback

When you hit the Hard Stage, you’ll feel a distinct physical stop that replicates the locking sensation of real brakes at maximum load.
It’s a tactile cue that helps you maintain optimal pressure just before the threshold of tire slip — ideal for perfect trail braking and faster lap times.

Effortless Integration

No full pedal rebuild required.
Simply mount and connect the THORP II module to your Initium Pedal Set, and it’s instantly ready to use.
With RaceHub software, you can fine-tune pedal curves, pressure scaling, and sensitivity for your ideal racing setup.
