Quick Answer

Assemble the SimXPro GT-RS frame first, then mount the XL GT Seat using the included slider for easy adjustment. The compact 40x80 aluminum profile design makes it straightforward to get a stable, personalized driving position.

Why the GT-RS Bundle Makes Setup Easier

The SimXPro GT-RS is designed as a compact but expandable cockpit. When you order it as a bundle with the XL GT Seat and Slider, all mounting hardware is included and the components are matched to work together. This reduces guesswork compared to buying a frame and seat separately from different brands.

The XL GT Seat offers wider cushioning for larger drivers or those who prefer extra room, while the slider gives you fore-aft adjustability without needing to unbolt the seat. The trade-off is that the slider adds a small amount of height, so tall drivers may need to lower the seat mounting brackets to maintain a good eye line relative to the wheel.

Tools You Will Need

You need a metric hex key set (5 mm and 6 mm are most common for the GT-RS), a torque wrench if you want to follow exact specs, and a soft mallet for aligning profile slots. A spirit level helps ensure the rig sits flat on your floor. Have a clean, level workspace large enough to lay out the aluminum profiles.

Step-by-Step Assembly Guide

  1. 1. Lay Out and Identify Profiles: Unpack the box and separate the aluminum profiles by length using the included diagram. The longest pieces are the side rails; the shorter ones form the pedal deck and wheel mount. Place the T-nuts and corner brackets nearby. Common mistake: mixing up left and right side rails. They are symmetrical but the slot orientation matters for bracket alignment.
  2. 2. Assemble the Main Frame: Connect the side rails with the cross members using the supplied corner brackets. Tighten the 6 mm bolts finger-tight first, then torque to about 12 Nm once the frame is square. Use a spirit level on the cross members to ensure the frame is not twisted. Do not fully tighten any bolt until the whole frame is loosely assembled; this prevents alignment issues later.
  3. 3. Mount the Pedal Deck: Slide the pedal plate into the front slots of the side rails. Adjust the angle and distance to your preferred pedal position, then tighten the bolts. If you have a load cell brake, position the plate so you can brace against the seat without sliding. Set the pedal plate angle before tightening the wheel mount; changing it later may require loosening the entire front section.
  4. 4. Install the Wheel Mount: Attach the upright profile to the side rails using the provided brackets. Mount the wheel deck plate to the upright. Adjust the height and tilt so your elbows are at roughly 90 degrees when holding the wheel. Tighten all bolts. Check that the wheel deck does not interfere with your legs when you sit in the seat. Adjust height before final tightening.
  5. 5. Attach the Seat Slider to the XL GT Seat: Bolt the slider rails to the bottom of the XL GT Seat using the provided bolts. The slider mechanism should face forward. Ensure the bolts are tight enough that the slider cannot shift under braking force. Use thread-locker on these bolts; vibration from driving can loosen them over time.
  6. 6. Mount the Seat Assembly to the Frame: Slide the seat (with slider attached) onto the seat mounting brackets on the frame. Adjust the fore-aft position by sliding the seat on the rails, then lock the slider lever. Test that the seat does not wobble side to side. If the seat feels too high, you can remove the slider and bolt the seat directly to the brackets, but you lose quick adjustability.
  7. 7. Final Alignment and Cable Management: Sit in the rig and check your reach to the wheel and pedals. Make small adjustments to the wheel deck tilt and pedal angle. Route cables along the profile slots using zip ties or Velcro straps to keep them out of the way. Leave a little slack in cables near moving parts like the seat slider so they do not pinch when you adjust position.

Product Facts

  • SimXPro GT-RS + XL GT SEAT + SLIDER: The SimXPro GT RS is a compact sim racing cockpit built from high quality 40x80 aluminium profiles for serious performance in a smaller footprint. The 40x80 profile is rigid enough for direct drive wheels and load cell pedals, yet the compact footprint fits tighter spaces without sacrificing stability.
