HGK BMW E92 Lexan (ThermoFormed) Window Set 4 mm

Developed specifically for motorsport and performance applications, the E92 Lexan (ThermoFormed) Window Set is crafted from high-quality polycarbonate (Lexan / Makrolon) sheet with a 4-millimetre thickness. Engineered for precision, each piece is thermoformed to replicate the exact curvature of the original equipment manufacturer (OEM) glass, ensuring a perfect fit with no compromise on aerodynamic integrity or visual clarity. The UV-protected surface maintains its transparency and resists yellowing or discolouration even under prolonged sunlight exposure, making it suitable for both competition and long-term outdoor use. With an approximate 50% reduction in weight compared to standard glass panels, this window kit significantly enhances vehicle agility, weight distribution, and overall performance efficiency.
