The Totim Racing Custom Foam Seat Insert Kit – 140 × 100 × 85 cm (Trapezoid Shape) is a large-format insert designed for cockpits that demand more material at the shoulder area and less at the thighs — a common seat geometry in GT, NASCAR, and WRC racing. Its unique shape helps achieve a natural upright driving position with improved lateral containment where it matters most.
The trapezoid profile works exceptionally well in seats with high shoulder bolsters, shallow thigh padding, or minimal seat angle, where a traditional rectangular foam fill might result in excess trimming or uneven support. This insert ensures optimal body contact along the spine, ribs, and shoulders — delivering comfort, control, and fatigue reduction over long stints and rough surfaces.
Like all Totim kits, it features a sealed black microfiber FIA-certified fire-resistant pouch, filled with two-part expanding foam that cures in under 60 minutes. The molding process is clean, tool-free, and fully customizable once set — just trim to fit belts, bolsters, and cockpit contours.
Best of all, the 140 × 100 × 85 cm trapezoid kit combines pro-level fitment with a geometry tailored to the unique needs of production-based or upright racing cars.
Available in Small and Large:
- Small: Compact applications or minimal padding
