You assemble the SIMGASM Sport cockpit in about two hours, using only the hex keys that come in the box. Lay out the 40 × 120 mm aluminium profiles, build the base frame loosely, square it, then fit the wheel deck, the pedal deck and the uprights. Only after a final alignment check do you torque every bolt in sequence.
That order matters more than strength or speed. A frame that is square from the start stays quiet and rigid under a strong direct drive wheelbase, while a frame that was tightened too early keeps creaking. This guide walks you through each step in plain words.
What do you need before you start?
Good preparation saves you most of the time you might lose later in the build.
Space, tools and a parts check
Clear about two square metres of floor. The finished Sport measures 580 × 1320 × 720 mm (W × L × H), so you also want room to walk around it. A carpet or a blanket protects both the floor and the anodised finish.
The box holds the aluminium profiles, the structural chassis brackets, the wheel mount you picked at checkout, the assembly hardware and tools, white assembly gloves, the assembly guide, the Apex side profile arm for a shifter or handbrake, a heel rest and rubber feet. A torque wrench is optional. A rubber mallet helps to seat profiles that sit a little tight.
What is not in the box
The seat, the seat slider, the wheelbase, the steering wheel, pedals and a monitor stand are sold separately. So check that those parts are ready, or at least ordered, before you start. That way you finish the build with your own driving position instead of a guess.

How do you build the base frame?
The base frame is the foundation, so this is the step where patience pays off most.
Lay out the profiles in order
Place every profile on the floor in the same order as the guide and the video show. Slide the T nuts into the slots before you join two profiles, because a forgotten T nut often means taking a corner apart again. Turn each bolt in until it touches, then stop.
Square the frame before you tighten
Here is the key trick. Keep all T nuts loose and measure both diagonals of the base. When the two numbers match, the frame is square. Only then tighten the corners in a cross pattern, a little at a time. The SIMGASM team says it simply: most assembly problems come from tightening too early, not from a missing part.
How do you fit the wheel deck and pedal deck?
Next you add the two parts that carry all the force from your hands and feet.
Wheel deck and uprights
Mount the uprights and the side profiles, then fit the wheel deck with the mount that matches your wheelbase. Bottom Mount covers supported patterns from Logitech, Fanatec, MOZA, Thrustmaster, SIMAGIC, PXN, Simucube, Asetek and VRS. Side Mount covers supported Fanatec, MOZA and SIMAGIC bases. The regular Front Mount suits supported Simucube and VRS bases, and the Asetek Front Mount is dedicated to Asetek. Keep these bolts slightly loose, because you still adjust height and angle later.
Pedal deck
The pedal deck takes standard load cell and hydraulic pedal sets. Its slots let you move the deck forward, backward and up in angle. The Sport carries a rated braking load of 300 kg at the pedal deck, which leaves a big margin for hard braking on a load cell. For a deeper look at that number, read how much braking force a cockpit needs.

How do you set your driving position?
A rig only feels right when it fits your body, so set it up in a fixed order.
Pedals first, then seat, then wheel
Start with the pedal deck angle. Then set the seat distance, and finish with the wheel height and angle. Working in this order stops you from chasing adjustments in circles. Your heels rest on the floor plate, your wrists reach the top of the wheel with a small bend in the elbow, and your knees clear the wheel deck.
Seat height and comfort
Seat height changes your view, your leg angle and your comfort over long races. Our guide on how high a sim racing seat should sit in your rig helps you pick a starting point. Because every mounting point slides along the profile, the same Sport frame suits a short driver in a GT position and a tall driver in a formula position.
How do you finish and check the build?
The last ten minutes decide how solid your rig feels on track.
Torque in sequence
Go round the frame and torque every bolt in the same order, corner by corner. Then check the diagonals once more. A Sport that is square from the start stays rigid under 20 Nm of direct drive torque. If you want to know which bolt does what, read which bolts and T nuts hold an aluminium rig together.
Route the cables and test drive
The Sport has integrated cable passthroughs, so guide USB and power cables through the profiles before your first session. Then drive a few laps, brake hard and turn the wheel from lock to lock. Listen for clicks and look for movement. After the first week of driving, check the bolts again, because new joints settle a little.

Who designed the Sport?
The Sport comes from a founder who still races, both on track and on screen.
Designed and tested as a complete simulator
Founder Johan Akkerman designed the complete SIMGASM range and holds final responsibility for product quality. He has raced since 2008, and he once welded his own first frame from used gas pipes. That practical start still shapes his view: a product needs to solve a real problem and be strong enough to last. Every SIMGASM product is tested as part of a complete simulator, not as a loose part.
Support from a Dutch team
SIMGASM is a Dutch company based in Wijk bij Duurstede. If you get stuck, email hello@simgasm.com and the team usually responds within one business day. Want to compare frame sizes first? Browse the SIMGASM Sport range or the full sim racing cockpit line.
Quick answers about building the Sport
Here are short answers to the questions new builders ask most.
How long does the assembly take?
Around two hours at a relaxed pace for a first aluminium rig. Your second build goes faster once you know where each T nut goes.
Do you need special tools?
No. The supplied hex keys are enough. A torque wrench and a rubber mallet make the job a bit easier.
Can you build it alone?
Yes, most steps work for one person. A second pair of hands helps when you lift the uprights into place.
Can you add a monitor stand later?
Yes. The side profiles carry a monitor stand, a keyboard tray, a shifter, a handbrake and a button box without any drilling.
