What it is
The Sim-Lab GT1 Evo is the Dutch brand’s entry point into aluminium-profile cockpits, built mostly from 40x80mm extrusion with two lengths of 40x40mm for the seat rails. It ships as a complete frame kit, pre-cut and powder coated, with the wheel deck, pedal tray, side mount, rubber feet and all the hardware in the box. No seat is included. At around $442 / £349 for the frame alone it sits at the affordable end of the profile tier, priced as a chassis you grow into rather than replace.
Who it’s for
You are the right buyer if you are stepping up from a wheel stand or a folding rig and you want a real profile frame without paying GT1 Pro or P1-X money. The appeal is the shared accessory range: every monitor mount, seat bracket and add-on built for the bigger rigs bolts straight onto the Evo, so nothing you buy now is wasted if you upgrade the chassis later. It also suits a belt base or a mid-tier direct-drive unit and a tight room, since with a light seat the whole rig comes in under 50kg with a base of just 135 by 58cm.
You are the wrong buyer if you are about to run a strong direct-drive base and never want to touch a bracing bar. At 15Nm and up the wheel mount shows movement, and while the open profile makes bracing easy, the GT1 Pro is the cleaner answer if you know high torque is coming.
In use
The build is the first pleasant surprise. It is a repetitive job of bolting profile together with gusseted, spring-loaded corner brackets, and most of it goes together in an afternoon. The downloadable schematic is thin, so run a build-video walkthrough alongside it for the small tips, like which way to orient the T-nuts. One quirk: you have to file the anti-rotation tabs off six brackets to mount them against the seat rails and wheel mount, which the updated bracket design makes fiddly.
Once it is together, the adjustability is the standout. The wheel deck is 5mm machined aluminium on a pair of 58cm uprights, with a 60-degree tilt range, 30 degrees either way, plus horizontal slide and height to 66cm. The pedal plate is the heavy part at 17kg of 5mm high-tensile steel, pre-drilled for everything up to high-end load-cell sets, and tilts up to 45 degrees off the side rails. None of this is quick to change on the fly, but it lets you dial in a position down to the millimetre.
On rigidity the Evo punches at its price. Tested with a belt base and aggressive force feedback the wheel mount stayed planted with very little movement. The 40x80mm profile is stiff enough for the torque most entry buyers run, and if you go strong there are easy ways to reinforce it.
What to watch out for
The headline caveat is torque. The 40x80mm frame is mid-weight, not the heavy 80x40 of the step-up rigs, so a 15Nm-plus base will introduce flex at the wheel mount. It is physics, not a fault, and bracing with extra profile sorts it, but it is work you should expect rather than be surprised by.
A few smaller things are worth knowing. No seat is included, so budget for one. The black anodised finish shows scratches more than the clear coat. Clearance between the shifter arm and the seat is tight on the compact frame, so a wider seat may force the shifter onto the side of the wheel mount. And the M6 washers you want for mounting pedals are not in the kit, so pick a handful up before you start.
Where it sits in 2026
The Evo’s job is to be the cheapest honest way into a Sim-Lab profile frame, and it does that. Against the GT Omega Prime Lite and the Advanced SimRacing ASR-1 it competes on build quality and wins on accessory depth, since the range is enormous and cross-compatible with the GT1 Pro and P1-X above it. Against a folder like the Playseat Challenge X it is a different proposition: bulkier and slower to set up, but rigid and endlessly expandable where the folder is neither. If you want one frame that adapts as your kit grows and you are happy to brace it when the torque climbs, the Evo earns its place. If a strong DD base is already the plan, spend up to the GT1 Pro and skip the bracing.
