Learn how to install and adjust Advanced Side Brackets for your Sparco GP seat. Step-by-step instructions, common mistakes, and setup tips for a perfect fit.

Quick Answer

Install Advanced Side Brackets by aligning them to your Sparco GP seat's mounting holes, securing with the included M8 hardware, and adjusting the angle to your preferred racing position.

Why Side Brackets Matter for Your Setup

Side brackets are the critical link between your seat and the chassis. They determine both the height and the tilt of your seating position. With Advanced Side Brackets, you get up to 30 degrees of adjustability, which means you can fine-tune your posture for better comfort and control.

A proper installation ensures safety and stability. Loose or misaligned brackets can cause unwanted movement during intense racing, which can distract you and even lead to injury over time. Taking the time to install them correctly pays off in every session.

What's in the Box and What You'll Need

Your Advanced Side Brackets come as a pair (left and right) and include all necessary hardware: 4 M8 screws (16mm) and 4 M8 washers. The brackets are made from 1/8-inch thick steel, so they're sturdy and designed to last.

Before you start, gather a few basic tools: a socket wrench or Allen key that fits M8 bolts, a torque wrench if available, and a clean workspace. It's also helpful to have a spirit level to ensure the seat is mounted evenly.

Step-by-Step Installation and Adjustment

Prepare Your Workspace and Seat: Place your Sparco GP seat on a clean, flat surface. Have the side brackets, screws, washers, and tools within reach. Ensure the seat is stable and won't tip over during installation. Check that you have all 4 screws and washers before starting; missing hardware can compromise the mount.
Align the Brackets: Position one bracket on each side of the seat, aligning the holes in the bracket with the mounting points on the seat. The brackets are designed to fit the Sparco GP seat's bolt pattern, so they should line up without forcing. If the holes don't align, don't force it—double-check that you have the correct bracket for your seat model.
Secure with Hardware: Insert the M8 screws through the washers and into the bracket and seat holes. Tighten them by hand first to avoid cross-threading, then use a wrench to snug them down. Aim for a firm fit, but avoid over-tightening which could strip threads. Use a torque wrench set to the manufacturer's recommended spec if available; otherwise, tighten until snug and then a quarter turn more.
Mount the Seat to Your Chassis: With the brackets attached to the seat, position the assembly onto your sim racing chassis. Secure the brackets to the chassis using the appropriate bolts (not included). Ensure the seat is centered and level. Use a spirit level to confirm the seat is even; an uneven seat can cause discomfort and poor pedal alignment.
Adjust the Angle: Loosen the bolts slightly to adjust the seat angle. The brackets allow up to 30 degrees of tilt. Lean back for a more relaxed position or tilt forward for a more aggressive, formula-style stance. Tighten the bolts once you find your ideal angle. Test the angle with your pedals and wheel in place; your knees should be slightly bent and your arms should reach the wheel without stretching.
Test and Fine-Tune: Sit in the seat and simulate your driving position. Make any small adjustments to the angle or height. Ensure all bolts are fully tightened and there's no play or movement. Take a few practice laps to confirm comfort and visibility. Re-check bolt tightness after your first session; new installations can settle and loosen slightly.
