Reasons of track purpose products are expensive:
Material Quality: Pre-preg dry carbon is among the highest quality carbon fiber materials available, known for its strength and lightweight properties. This material is typically more expensive than standard carbon fiber due to its enhanced characteristics and manufacturing process.
Performance Enhancement: This front lip is designed to improve aerodynamics significantly, which can enhance performance on the track. Products that offer actual performance benefits, especially in motorsports, generally command a higher price.
R&D and Production Costs: The development and manufacturing of specialized auto parts, especially those tailored for specific car models like the BMW E90/E92 M3, often involve considerable research and development. This includes testing to ensure fit and performance, which can add to the cost.
