You see a photo of a finished cockpit. Seat, wheel, pedals, triple screens, the lot. Then the box arrives and it holds aluminium beams and a bag of bolts. That gap between the photo and the box catches a lot of first time buyers.
So let us set expectations clearly. A sim racing rig is a chassis. It gives your hardware a fixed home. The hardware itself almost always arrives separately, and that separation exists for a good reason.
What ships inside the box?
A SIMGASM chassis includes the aluminium profiles, the structural brackets, the wheel mount variant you selected at checkout, the mounting hardware, the tools, a set of white assembly gloves and the assembly guide.
Higher tiers add more. The Sport arrives with the Apex side profile shifter and handbrake arm, a heel rest and rubber feet. The Hobby arrives with the Core side profile arm. Every tier ships flat packed, so a Hobby fits in one box and a Sport arrives in two.
What stays out of the box? The seat, the seat slider, the wheelbase, the steering wheel, the pedals, the shifter, the handbrake, the monitor stand, the display and any motion hardware. Bundles change that, so read the product page before you order.

Why does the seat arrive separately?
Because fit is personal. A bucket seat that suits a driver of 170 cm feels wrong for someone at 195 cm, and shoulder width varies as much as height. Bundling one seat with every chassis would force half of all racers into the wrong shell.
Driving style matters too. A fixed bucket holds you tight during long stints, while a reclining seat suits a shared setup and a more relaxed position. Our comparison of bucket seats versus reclining seats explains which suits which racer.
Mounting adds a third variable. Side mounts and bottom mounts use different hole patterns, and a slider changes the height. Browse the sim racing seat range and match the pattern before you order brackets.
Why does the wheelbase arrive separately?
Every wheelbase bolts down differently. Some use an underside pattern, some use a front flange, some clamp on the sides. That is exactly why SIMGASM sells four mount variants for each chassis.
Bottom Mount covers supported patterns from Logitech, Fanatec, MOZA, Thrustmaster, SIMAGIC, PXN, Simucube, Asetek, VRS and Conspit. Front Mount covers supported Fanatec, Simucube and VRS front patterns. Side Mount covers supported Fanatec, MOZA, SIMAGIC and Conspit models. Asetek Front Mount serves supported Asetek units.
Pick the chassis for its profile depth, then pick the mount for your specific model. If you still weigh up bases, the wheelbase collection lists what fits which tier.

What do you still need for a complete simulator?
Five things beyond the chassis. A seat with brackets, a wheelbase, a steering wheel, a pedal set and a display solution. Add a PC or a console, and you have a working simulator. The complete simulator range shows how those parts come together.
Order matters more than most racers expect. Buy the chassis and the pedals first, because those two components decide consistency. A rigid frame and a good load cell set improve lap times more than an expensive rim ever does.
Screens come next, then the extras. A shifter, a handbrake, a button box and tactile transducers all add immersion once the core setup feels right.
How long does assembly take?
Plan an evening. Owners regularly report a full build in around two hours by following the manual, and every chassis ships with the tools it needs. A downloadable manual and an assembly video support the process.
Our article on bolts and T nuts explains the torque work that keeps it rigid afterwards, and the assembly guide in the box covers the build order itself.
Does buying separately cost more?
Rarely, and it usually costs less over time. Separate components let you spend where it matters and upgrade one part at a time. You replace a wheelbase after three years while the chassis, seat and pedals stay exactly where they are.
Compatibility protects that investment. Every SIMGASM tier accepts the same accessory range, so an upgrade from Hobby to Sport keeps your monitor stand, your shifter arm and your seat brackets in play.
Profile depth guides that choice. Our overview of aluminium profile sizes shows which tier suits your current hardware and your next one.

How do you plan the whole build?
Write down your wheelbase model, your pedal type, your seat size and your screen setup. Those four answers decide the chassis tier and the mount variant in one pass.
Then compare the tiers directly. The complete sim racing rig collection lists profile size, footprint, weight and rated braking load on every product page, so nothing surprises you after delivery.
Q&A
We answer a few questions that come up often:
Does a sim racing rig come with a seat?
Not as standard. The chassis includes profiles, brackets, the selected wheel mount, hardware, tools and the assembly guide. Seats are sold separately unless a bundle states otherwise.
Do I need seat brackets as well as the seat?
Yes, in most cases. Brackets connect the seat shell to the chassis rails, and a slider adds forward and backward adjustment on top of that.
Does the rig include a monitor stand?
No. Integrated and free standing stands are separate products, which lets you match the stand to your screen size and mounting preference.
Is the wheel mount included?
Yes. You choose Bottom Mount, Front Mount, Side Mount or Asetek Front Mount at checkout, and that mount ships with the chassis.
Can I add a shifter and handbrake later?
Easily. The side profile arm ships with the chassis, and the T slots accept extra mounts anywhere along the beam.
What tools do I need for assembly?
None of your own for a standard build. The mounting hardware, the tools and a set of white gloves arrive in the box together with the assembly guide.
