Evolution E-Types ‘standard’ frames are uprated compared to the original frames and are sufficient for road and light track use. In addition to aerospace-grade, high-tensile-strength steel, Evolution also utilise wider and thicker frames in order to increase strength and improve red rigidity as standard. However, due to popular demand, Evolution are pleased to offer further enhanced frame sets for further rigidity for our clients that wish to utilise their E-Type for heavy track use and racing purposes.
