Some SIMGASM accessories fit other aluminium rigs, but not all of them, and never by default. Parts that bolt straight into a standard profile slot, like the wheelmount side plates for any 4080 profile, have the best chance. Parts built for the SIMGASM system, like the side arms and cupholder, are designed and tested on SIMGASM cockpits, seats and monitor stands. So before you buy for a Trak Racer, Sim Lab or other profile rig, check three things: profile size, slot width and bolt size.
This guide explains what makes an accessory fit, which rigs are a good match and where you should stop and ask first.
What decides if an accessory fits a rig
Fit comes down to how the part connects to the frame, not to the brand on the box.
Most modern sim rigs use aluminium profile. That is a long bar with a slot along every side. You slide a T nut into the slot, put the part on top and tighten a bolt into the T nut. When the slot, the T nut and the bolt all match, the part holds. When one of them is off, it does not.
That is why a single number on a product page tells you so much. A profile named 40x80 is 40 mm wide and 80 mm deep. The four SIMGASM cockpits use a 40x40, 40x80, 40x120 or 40x160 main profile. If you want the full background, read our guide on which aluminium profile size a sim racing rig needs.
Slot width and T nuts
Profiles in the 40 series from most sim racing brands use a slot that takes 8 mm T nuts. That makes them similar on paper. Still, small differences in slot shape and T nut style exist between suppliers, so a T nut from one brand does not always sit perfectly in another. Our guide on which bolts and T nuts hold an aluminium rig together covers the details.
Which SIMGASM accessories fit other profile rigs?
Look for parts that SIMGASM describes as universal or as fitting a profile size, not a cockpit model.
The clearest example is the wheelmount side plate. SIMGASM states that these plates are compatible with any 4080 profile and work with both flat mounted and front mounted wheel setups. They also come in black, blue, gold, red and white, so you can add colour to a rig from another brand.

The accessory holder is another flexible part. SIMGASM describes it as a universal holder for simulator and workstation setups, to mount in a convenient spot in the rig or workspace. A floor mat is even easier, since it simply lies under any rig.
Which parts are made for SIMGASM rigs only
The Apex and Core side arms are listed for the Hobby, Club, Sport and Pro cockpits. The cupholder is listed for SIMGASM seats, monitor stands and chassis. That does not mean they never work elsewhere, but SIMGASM does not list them for other brands. On another rig, you take that risk yourself.
How do other brands compare?
The closer a rig is to a standard 40 series profile build, the better the odds.
Rigs from brands like Trak Racer and Sim Lab use aluminium profile frames, so the basic idea of slot and T nut is the same. That makes a part like the side plate a realistic fit, as long as the profile size matches. Steel tube cockpits are a different story. A Playseat Trophy or a Fanatec CSL cockpit has no profile slots, so profile accessories need extra clamps or brackets, and most of them do not fit at all.
A wheelbase bracket is a special case. The SIMGASM side mount bracket set holds compatible side mounted wheelbases from brands like Fanatec, MOZA and SIMAGIC, and it is built to integrate with the Club, Sport and Pro. On a rig from another brand, the bracket pair alone is not enough. You also need the matching mount parts of that rig.

A quick check before you order
Measure your main profile and side profiles. Check the slot width and the T nut size your rig uses. Look at the bolt holes of the part on the product photos. If all three match, the part has a real chance. If one is unclear, send a photo of your rig to the SIMGASM team first. They answer within one business day, by email or WhatsApp.
When a full SIMGASM rig is the easier route
If you plan several upgrades at once, matching parts save you a lot of trial and error.
Every SIMGASM accessory is designed by founder Johan Akkerman and tested as part of a complete SIMGASM simulator. He knows the other side well too: before SIMGASM he worked at Trak Racer, where he helped develop the TRX chassis and designed the TRX seat. SIMGASM builds its cockpits, arms and holders to work together as one system. A part that fits on the first try saves an evening of filing and swapping T nuts.
The Club is a good match for drivers coming from another 40x80 rig. It uses a 40x80 main profile, carries a rated braking load of 200 kg at the pedal deck and ships with the Core side arm. If you want to read more about that size, see what a 40x80 aluminium profile means.

Questions about accessory fit on other rigs
Here are the quick answers to the most asked fit questions.
Do SIMGASM side plates fit a Trak Racer rig?
SIMGASM states the wheelmount side plates fit any 4080 profile. Check that your Trak Racer wheel mount uses that profile size before you order.
Do SIMGASM accessories fit a Playseat?
Mostly not. Playseat cockpits use steel tubes without profile slots, so profile accessories do not bolt on directly.
Does the cupholder fit other rigs?
The cupholder is designed for SIMGASM seats, monitor stands and chassis. On other rigs, fit is not tested.
Who do I ask when I am not sure?
Send the SIMGASM team a photo of your rig and the part you want. They reply within one business day.
