The most common email I get is some version of this: I have a Trak Racer or a Sim-Lab, the seat that came with it is not good enough, will a Sabelt fit. The answer is yes, with the right side brackets, and this guide is what I send back. Read the whole thing before you buy anything, because the mistake people make is ordering the seat first and the brackets never.
Why it works at all
Every Sabelt seat on this site is side mounted. The shell has fixing points on both sides and the seat hangs between two brackets that bolt down to the rig. That is the standard motorsport way of mounting a seat, and it is also how Trak Racer and Sim-Lab mount theirs. Both brands build cockpits from aluminium T slot profile, and both sell side mount seat brackets that clamp into the profile slots with T nuts and rise up to meet the seat. So the question is never whether a Sabelt fits a Trak Racer. It is which brackets, and whether the hole spacing lines up.
What to measure
Two numbers decide everything. The first is the distance between the fixing holes along each side of the seat shell, front to back. The second is the width across the seat between the two sets of fixings, which sets how far apart the two brackets sit on the rig. On the Sabelt motorsport range those figures are published on some models, the Taurus has side fixings at 290 mm and the GT-PRO at 340 mm for example, and for the SRS-1, SRP-1 and SRX-1 sim seats I will send you the drawing if you ask. On the rig side, Trak Racer and Sim-Lab brackets are slotted rather than drilled so they cover a range of spacings [CHECK], which is what makes this straightforward most of the time.
Trak Racer
Trak Racer sell their own seat brackets in a couple of heights and a sliding version [CHECK]. They are designed for the seats Trak Racer sell, but because they are slotted side mount brackets they take any side mounted seat in the normal size range, including a Sabelt [CHECK]. The TR160 and TR8 both use a flat profile deck under the seat with slots running front to back, so the brackets can be positioned anywhere along the rig for reach and slid apart to match the seat width. Fit the brackets to the seat first on the floor, then drop the assembly onto the rig and clamp it. Do it the other way round and you will spend an hour lining up holes you cannot see.
If you want fore and aft adjustment on a shared rig, fit sliders between the seat and the brackets. The Sabelt SRS and SRX sliders and the SRP sliders are built for those seats, and they raise the seat by the thickness of the slider, so check your head to monitor line if you run a chassis mounted screen.
Sim-Lab
Sim-Lab cockpits are the same story with more options. Sim-Lab sell seat brackets and also a seat slider set, and because the whole rig is standard T slot profile, third party brackets from the general sim racing market fit as well. The GT1 Evo and the P1X Pro both use profile rails under the seat rather than a flat deck, which means the bracket clamps into the top slot of the rail and the seat position is set by where along the rail you clamp. The only thing to watch is that some Sim-Lab bracket kits are sized for the Sim-Lab seats and the hole spacing may need the slotted holes to be at the far end of their range for a wider shell. Measure before you order.
Which Sabelt seat on which rig
For a GT position rig, which is what most Trak Racer and Sim-Lab owners have, the SRS-1 is the direct upgrade. It is reclined, it is the right shape for the position the rig already puts you in, and it is $699. For an upright rig or someone who drives rally and road cars, the SRX-1. The SRP-1 formula seat only makes sense if your rig is set up in a formula position with the pedals raised and the seat laid back, because a formula shell in a GT rig puts your knees in the wheel. The motorsport seats all fit the same way with side brackets, with the note that the bigger halo seats like the Taurus and GT-635 are wide at the shoulder and can foul the wheel upright on a narrow rig, so check the width against your frame first.
The Sabelt brackets
To be clear about what I sell. The Sabelt seat brackets at $109 are made for the Sabelt cockpits and their profile, and I would not assume they fit a Trak Racer or Sim-Lab rail without measuring. For those rigs, the rig maker's own side brackets are usually the cleanest answer, and the Sabelt seat bolts to them. If you send me your rig model I will tell you which bracket, and if the honest answer is buy the Trak Racer bracket, that is what I will say.
What to avoid
Do not mount any motorsport seat through the bottom of the shell unless the manufacturer says you can. Sabelt shells are side mount and drilling the base is a good way to crack it. Do not use a slider that is rated for an office chair. Do not over tighten T nuts in aluminium profile, they strip and then you are buying new rail. And do not skip the sliders on a rig you share with someone of a different height, because the alternative is loosening four bolts every time you swap.
If you get stuck, email me the rig model, the seat you want and a photo of your seat rails, and I will specify the exact bracket. I answer these myself, same day most of the time.
