GT-Pro Fixed Fiberglass Sim Racing SeatvsRS Adjustable Seat

The Bottom Line

Choosing between the Trak Racer GT-Pro and the 6sigma Racing RS Adjustable Seat comes down to a fundamental choice: the rigid, locked-in feel of a fixed fiberglass bucket versus the casual comfort and adjustability of a reclining PU leather seat. Both options target budget-conscious racers but force you to accept very different compromises in rigidity and build quality.

Critical Warning

If you run high-end load cell pedals with stiff elastomer stacks, be prepared for movement in both seats. The Trak Racer GT-Pro suffers from noticeable fiberglass flex and lumbar "popping" under heavy braking, while the 6sigma RS Adjustable is prone to annoying squeaks and creaks at its reclining hinge mechanism.

Pro Tip

Because the GT-Pro fabric traps body heat during long sessions, adding a simple USB-powered seat cushion fan can prevent sweating. For the RS Adjustable, swap out the poorly designed stock brackets for standard aftermarket steel brackets to make tilt adjustments actually usable.

Why choose Trak Racer GT-Pro

6.8
Sim Racing Score

  • Immersive Bucket Design: Offers a highly authentic, locked-in racing position that keeps your hips firmly planted during high-G cornering.
  • High Weight Capacity: Rated for up to 200 kg, providing a wider, more accommodating shell than typical tight-fitting formula seats.

Why choose 6sigma RS Adjustable

6.2
Sim Racing Score

  • Reclining Versatility: Allows you to easily adjust the backrest angle for casual driving, flight sims, or general desk work.
  • Plush PU Leather: Provides a softer, more cushioned initial feel that is easier to wipe clean than fabric alternatives.

The Verdict

If you prioritize a rigid, immersive racing posture and can tolerate thin padding and heat buildup, the Trak Racer GT-Pro is the better performance tool. However, if you want a casual, adjustable seat for multi-purpose use and do not mind some mechanical squeaking under heavy braking, the 6sigma RS Adjustable offers decent comfort for average-sized drivers.
