Aluminium profile costs a fixed amount per metre. Brackets cost a few euros each. Add a saw and a weekend and you have a rig for far less than a finished product. That is the theory, and plenty of racers start there.
The practice looks different. Most people who finish a DIY build report a total that lands close to a ready designed chassis, plus a stack of hours they never planned for. Understanding why saves you both.
What does a DIY 8020 rig really cost?
Four cost blocks appear. Extruded profile by the metre, cut to length. Brackets, gussets and plates. Hardware such as T nuts, bolts and end caps. Then the specific parts: a wheel mount plate, a pedal deck, seat rails and feet.
Cutting adds the first surprise. Aluminium profile arrives in long lengths, so you either pay for cut to size service or buy a saw and accept waste. Both routes add cost that the per metre price never shows.
Powder coating adds the second. Raw silver extrusion looks industrial, and a coloured finish on a home build means a trip to a coating shop. Coating a full frame often costs more than the brackets did.
What does a ready designed chassis actually buy you?
Engineering decisions, mainly. Profile depth, bracket thickness, deck angles and mounting patterns all arrive solved. A SIMGASM chassis ships with the profiles, the structural brackets, the wheel mount you chose, the hardware, the tools, gloves and the assembly guide.
Rated figures come with it. Each tier publishes its main profile, its footprint, its weight and its rated braking load at the pedal deck, so you match the frame to your hardware before you pay. Our overview of aluminium profile sizes for a sim racing rig explains how to read those numbers.
Compatibility follows. Four wheel mount variants cover supported models across ten major brands, and the model level tables remove the guesswork that kills so many DIY builds.
Cover also comes with it. SIMGASM ships every chassis with a two year warranty and a thirty day risk free return window, and the rigs carry a 4.97 star average across 178 verified reviews. A home build offers none of that.

Where does DIY genuinely win?
Two situations, and both stay narrow. The first is a genuinely unusual shape, such as a full width truck simulator or a frame built around an awkward room. No manufacturer designs for that, so you build it yourself.
The second is when the workshop already exists. A saw, a drill press and leftover profile in your garage drop the marginal cost sharply, and the building itself becomes part of the hobby.
Outside those two cases the numbers converge fast. Individual aluminium components already cost hundreds of euros, and hardware, coating and your own weekends close the remaining gap. Most racers who price it honestly end up buying.
How do you compare fairly?
Price the same specification on both sides. Take a 40 x 120 mm main profile, a rated pedal deck, a wheel mount that fits your base, a shifter arm, a heel rest and rubber feet. Then add coating, cutting, shipping and hardware to the DIY column.
Add resale value too. A recognised chassis holds value and sells quickly, because the next buyer recognises the specification and finds spare parts. A home build sells slowly and usually for parts, which matters more than people expect after three years.
Finally, add the support question. A SIMGASM chassis comes with a downloadable manual, an assembly video, a two year warranty and a team of sim racers to ask. Owners regularly report a full build in about two hours by following that manual, against several weekends for a scratch design. Our article on what a sim racing rig includes sets out exactly what arrives in the box.

Where should your money go first?
Frame and pedals. Those two decide consistency, and consistency decides race results far more than an expensive rim. Screens and extras follow once the core setup feels solid, and the complete simulator range shows the finished combinations.
Then protect the upgrade path. A chassis that accepts the same accessories across every tier means your monitor stand, shifter arm and seat brackets survive your next wheelbase. Correct assembly protects it too, and our guide to bolts and T nuts in an aluminium rig covers the torque work involved.
SIMGASM designs and manufactures these rigs in the Netherlands as a European manufacturer with patented and patent pending products, which is why the published figures and the compatibility tables hold up.

Q&A
We answer a few questions that come up often:
Is it cheaper to build a sim rig yourself?
On paper often yes, in practice rarely. Cutting, coating, brackets, shipping and iteration close most of the gap, and your own hours close the rest. A ready designed chassis also arrives with a warranty, a manual and a proven driving position.
How long does a DIY build take?
Plan several weekends including design, ordering and adjustment. A designed chassis assembles in roughly two hours with the supplied tools and manual.
Can I build a rig from wood instead?
You can, and it works for a light wheel. Wood struggles with strong direct drive torque and offers almost no adjustability once it is screwed together.
Does a DIY rig hold its value?
Usually not. Buyers pay for known specifications and available spare parts, so home builds tend to sell slowly and cheaply. A recognised aluminium chassis keeps a far larger share of its value.
What is the biggest risk of building your own?
Mounting geometry. A wheel deck or pedal deck at the wrong height or angle affects every session, and correcting it means new parts rather than a quick adjustment.
Should a first time buyer ever go DIY?
Only with workshop experience and a clear plan. A designed entry level chassis such as the Hobby in orange gives a proven driving position for a first dedicated simulator.
