A sim racing cockpit needs a pedal deck that stays still under your hardest brake stop. For a normal pedal set, a 40x40 frame with a rated braking load of 150 kg is enough. For a stiff load cell brake that you push often and hard, choose a frame with more reserve, such as the SIMGASM Club with a rated braking load of 200 kg on the pedal deck.
Braking is the biggest force you put into a rig. Your legs are far stronger than your arms. So if a cockpit flexes anywhere, you usually feel it at the pedals first. Let's look at what that means in practice.
Why is braking force so important for a cockpit?
When you brake in a real car, the pedal pushes against the car's body. In a sim rig, the pedal pushes against the pedal deck, and the deck pushes against the base frame. Every kilo of force from your leg ends up in that frame.
A load cell brake measures pressure instead of travel. That is great for consistency, because your brain remembers force better than distance. It also means you press much harder than on a simple spring pedal. The harder you press, the more your frame needs to resist.
If the pedal deck moves, you lose part of that pressure to frame movement. Your brake point drifts, and trail braking into a corner feels vague. That is why racers call a stiff pedal area the heart of a good rig.
What does a rated braking load of 200 kg mean?
SIMGASM lists a rated braking load at the pedal deck for every cockpit tier. It shows how much braking load the deck is rated for. The Hobby is rated at 150 kg, the Club at 200 kg and the Sport at 300 kg.
This is a rating for the frame, not a target for your leg. You never need to push 200 kg. The point is reserve. A deck that is rated well above your real braking force stays calm and quiet, so your brake feel stays the same after an hour of racing.

Where does the extra strength of the Club come from?
The Club uses a 40 × 80 mm main profile, where the Hobby uses 40 × 40 mm. The base is twice as tall, so it resists bending far better when the pedal deck is pushed forward. Metal mounting components are matched to each cockpit tier, so the brackets fit the load of that frame.
The step to Sport adds a thicker pedal tray and base structure. For most home racers with one strong load cell brake, the Club already gives plenty of reserve.
Do you need a stronger pedal deck for load cell pedals?
Not always, but often. Ask yourself three short questions. Do you use a load cell or hydraulic brake? Do you set it stiff? Do you race several times a week? If you answer yes two or three times, pick a frame with more reserve.
Your seat position also plays a role. In a GT position, you push the pedals more forward. In a formula position, your legs are higher and you push more upward and forward at the same time. Our guide on GT or formula seating position explains both layouts in detail.
Also check the seat mount. If the seat slides back when you brake, the pedal deck is not the problem. A locked seat slider or a stiff seat bracket solves that. You find fitting seats in the SIMGASM sim racing seats range.

How was braking stiffness judged in the SIMGASM design?
SIMGASM founder and product designer Johan Akkerman races in real life as well as in the sim. He won the DNRT BMW E30 Cup and Endurance Series championships in 2023 and 2024. In real cars, the brake pedal is your main tool for lap time. That experience is part of why SIMGASM treats pedal geometry as a performance factor.
Every SIMGASM product is tested as part of a complete simulator, with seat, wheel and pedals in place. The team even put its own Hobby frame through a strength test on video, which you see above.
What is the difference between flex and play?
Flex is the frame bending under load. Play is loose parts moving before the frame even takes the load. Play often comes from bolts that settle after the first few sessions. So check and tighten all bolts after your first week. That simple step removes most of the movement people blame on the frame.

Which cockpit gives your brake the right support?
Use a simple rule. A basic pedal set on a relaxed setting fits well on a 40x40 frame. A stiff load cell brake fits a 40x80 frame. A heavy hydraulic set, motion or an extra strong wheelbase fits the Sport or Pro.

Questions about pedal braking force
How much braking load does the SIMGASM Club handle?
The Club pedal deck has a rated braking load of 200 kg. The Hobby is rated at 150 kg and the Sport at 300 kg.
Is a 40x40 cockpit enough for load cell pedals?
For a load cell brake on a moderate setting, yes. If you set the brake very stiff and race often, a 40x80 frame gives more reserve.
Why does my brake feel different after a few weeks?
Bolts settle after the first sessions. Tighten all bolts again after a week, and check the seat mount as well.
Are pedals included with a SIMGASM cockpit?
No. Pedals, seat, wheelbase and monitor stand are sold separately, so you combine the hardware that suits you.
