Asetek La Prima Sim Racing Pedals Brake & Throttle

Asetek La Prima Sim Racing Pedals Brake & Throttle


nspired by real-life racing, the La Prima™ Sim Racing Pedal set has been thoroughly tested by racers and sim racers alike. With that feedback in mind, the pedals were engineered and designed to give you a realistic brake experience without breaking the bank.

“Probably the best pedals, that I’ve ever tested at this price point, in terms of that overall build quality and materials” -Will Ford, Boosted Media

While La Prima is our entry-level series, make no mistake! Unlike many other flimsy entry-level pedals on the market, we have not compromised on quality, materials, design, or adjustability, as these are identical to its mid- and high-end siblings Forte® and Invicta™, With Invicta™ arguably being the best sim racing pedals ever built.

Instead of compromising on quality, performance or reliability, we have taken a differente route. Rather, we have chosen to make it an upgradeable pedal set. This means, that you can upgrade to the full Forte® experience by upgrading the LED and Throttle adjustment system. You can also upgrade the M.L.C.P.C.™ brake cylinder to a T.H.O.R.P.™ hydraulic brake cylinder.

If you want the feeling of real racing and quality materials without breaking the bank, the La Prima™ pedal set is for you! Using The M.L.C.P.C. brake pedal technology, the brake pedal on the La Prima™ pedal set can be adjusted from soft to hard (by changing elastomers), and it will stay that way – unlike many other sim racing pedals on the market, where the hardness and feel will degrade over time.  

When buying an Asetek SimSports ® pedal set, you buy into a platform, making it simple and easy to upgrade to Forte ® or Invicta™ at a later point!
You simply buy your desired upgrade kit, and all you pay for is the upgrade itself. As such, your purchase of the La Prima™ pedal set will be future-proof. Better for you – better for the environment.

  • The M.L.C.P.C. System


    A hard brake pedal is faster because you can brake later, and it is required to properly trail brake and use your muscle memory to do so, as explained later. You can consider a race car braking system as 2 stages:

    The “soft stage”: When you apply pressure on the pedal, it will move 10-20 mm (measured on the pedal plate), while you build up pressure, while the caliper pistons are traveling to and pushing the brake pads lightly against the brake disc, and to compensate for the small amount of play in all the mechanical parts on the pedal system that is required for them not to seize up.

    The “hard stage”: When hydraulic pressure is built up, the brake pads are squeezing the discs hard and all mechanical play is compensated. In this stage, your foot is basically “pressing against a wall”, because now your muscles are pressing directly against the hydraulic forces (the brake fluid). Since the fluid cannot be compressed, you will feel the pedal is hard. When a race car driver complains about a “long” or a “soft” pedal, it is typically because there is air in the system, and since air CAN be compressed, the pedal will feel soft and long. The mechanics then bleed the brakes for air, meaning there is only fluid left in the system, and the pedal is once again hard after passing the “soft stage”.

    Most mechanical sim racing pedals on the market, have an “unlimited” travel, as it is essentially a question about how hard you squeeze the elastomer. Oftentimes, the elastomer is overworked (compressed more than designed for) and it provides a spongy and inconsistent brake feel and eventually the elastomer will break because of being overworked out of spec. But worst of all: with the long brake pedal travel, you will have to brake earlier to build up full brake pressure!

    In our quest to mimic the perfect race car feel, we have implemented a mechanical stop in our M.L.C.P.C. brake system. You can adjust the hardness of the “soft stage”, by changing elastomers, but the travel will be limited to 15-25mm on the pedal plate (around 12mm piston travel in the M.L.C.P.C cylinder) to simulate the “hard stage” where the pressure has built up, and the feeling is like “pressing a wall”. In the transition between the soft and hard stage (when hitting the mechanical stop) we have implemented a rubber damper, which will simulate the fully engaged brake caliper but still enable the load cell sensor to measure additional pedal pressure, which again allows for a perfect trail braking. This is the same feeling you get in a real race car.

    Because the load cell sensor is implemented with a gearing (ratio between pedal pressure and load cell deflection), any user using from the softest elastomer to the hardest elastomer will experience the full load cell resolution of around 4000 points in only 12mm inside the M.L.C.P.C cylinder from released pedal to 2nd stage. That is a resolution of 1/5th of a human hair!

    And THAT is the Asetek SimSports Forte M.L.C.P.C. difference!

    By adjusting the piston and thumb lock nut in front of the mechanical brake cylinder, you can adjust the preload of the system to closely mimic the gap you will experience in a real car (between disc and brake pad). We have made this adjustable, so you can have the feeling just the way you like it – and just like your favorite car. Using the RaceHub software, you can also adjust your dead zone on the brake pedal. This allows you to rest your foot on the pedal without getting inputs to the game.

    It may surprise you, but as described above, having a hard brake pedal will help you get around the track faster. It has to do with muscle memory and efficient trail braking.

    Having a hard brake pedal will allow your muscle memory to be trained to perfection. Muscle memory is the subconscious telling your muscles just the right amount of pressure, leaving your conscious mind to take care of more important things at that moment – like watching traffic or hitting apex. Your muscle memory is not wired to remember a position. Try to lift your hand with your eyes closed and reach the same spot within 0.5 mm 10 times in a row, and you will get the point. But your muscle memory can memorize a pressure extremely accurately, meaning going around a track, your muscle memory can make you brake the same way again and again. This cannot be achieved with a soft pedal – especially when trail braking.

    Furthermore, a hard and short travel brake pedal will allow you to brake later. Imagine having a brake pedal with 50 mm (common for many sim racers) of travel versus a brake pedal with almost zero travel. Imagine this scenario: You are going 300 km/h down a straight. With the long travel brake, it will physically take you perhaps 1/10 of a second more to reach full braking power. On the stiff brake pedal, you will reach maximum braking power instantly. If you have three hard braking zones on a track, you will lose 3/10 of a second each lap.

    The Top 10 in F1 or GT3 is frequently determined in way less than 3/10 of a second. The conclusion is that we at Asetek SimSports® have developed the our pedals to replicate a real race car. Why? Because it is the fastest but may not be what feels the most comfortable. It is your choice whether to be the quickest or have a brake pedal that feels soft and comfortable.



    Should you wish to change the pedal stops, and thereby the angle of the pedals, it can be done entirely toolless. It will require you to recalibrate the pedals and remove the brake cylinder at the pedal arm and adjust the rod length to prevent any preload on the brake cylinder.

    At Asetek SimSports®, we want to be industry leaders, both in quality and thought. We want to revolutionize the definition of entry-level equipment in Sim Racing. What others call high tier, we call entry-level.

    When you choose Asetek SimSports®, you buy into a product platform with an upgrade mindset.

    La Prima™ is our entry-level series, but it is not really entry-level products. Generally, entry-level often means lower quality materials, flimsy build quality equaling reliability issues, and shorter product lifetime. Our approach is different; we have not compromised on quality because we want the same reliability and excellent performance throughout our product range. We keep the die-cast aluminum, same quality ball bearings, adjustment screws, and more, but the way we achieve a lower price point is that we have simplified some of the milling processes, and taken some features off. As an example, we have removed the RGB light bar, which is a cool feature, but for most people it will not add to performance.

    It is not only the no-compromise focus on quality and performance that is revolutionizing. It is the upgrade philosophy of Asetek SimSports®. The La Prima™ Pedals should be perceived as a platform where you can get in at a lower price point, and you can upgrade the pedals in stages as you can afford them, or as you progress and grow as a driver. It is better for you, it is better for us, but most importantly, it is better for the environment because you don’t throw away all the other stuff you have bought. You reuse everything you have already and get the option to upgrade to the pedals you desire. To upgrade, you simply buy your preferred upgrade kit, and all you pay for is the upgrade kit itself.

  • Overview


    As well as being inspired by real-life racing, La Prima™ Pedals have been thoroughly tested by both racers and sim racers, and with that feedback in mind, the pedals are engineered and designed. 

    It is not a coincidence that a race driver wants a brake pedal that, when fully depressed, feels like pushing a wall. Furthermore, La Prima™, while not hydraulic, will still offer you the “hydraulic sensation” of a fully depressed brake pedal, where you can still pressure, modulate and trail brake thanks to the 2-stage system inspired by Invicta™. To simulate the real-life experience, when applying 100% pressure to the brake, you will be able to apply further pressure, which gives the feeling of compressing the fluid in a real-life brake system.  

    The Asetek SimSports ® M.L.C.P.C.™ (Mechanical Load Cell Powered Cylinder) brake cylinder gives you, shy of a full hydraulic system, an authentic race car driving experience. The sim racing pedal set is in every sense Made in Denmark – designed, engineered, and assembled in Denmark. The brake cylinder features a custom-designed load cell sensor that detects actual changes in force on the pedal face, up to 180 kg of force on the pedal face itself (with hardest elastomer 4000N depressed 12mm / until 2nd stage is engaged), making it the closest you will come to a realistic brake experience.

    Because the load cell sensor is implemented with a gearing, any user using anything from the softest to the hardest elastomer will experience the full load cell resolution from the released pedal to 2nd stage of braking. 

    Why does it matter? When applying brake pressure as late as possible, you want to be able to use muscle memory to replicate that trail brake feeling going into the corner. By using muscle memory, your brain is wired to be able to brake at the same spot over and over on the track. 

    Conversely, if you use a soft pedal, you will have to rely on foot or pedal position, disallowing your brain the ability to replicate with the same accuracy, and you will – guaranteed – lose important lap time. Just consider the fact that on a racetrack with 10 corners, gaining or losing 1/10 of a second on the brake means 1 second on your lap time. 

    The design on the La Prima™ Pedals is engineered with user experience in mind, where all adjustable elements are colored to get you started quickly and to ensure intuitive and mostly toolless usage. The sim pedals are highly adjustable to help you channel your inner race car driver by changing the travel and hardness settings to your exact preference.
