All of our Sigma, Duratec and K-series performance upgrades are based on considerable
experience in this field, not conjecture or just repeating manufacturers catalogue information. Using only the highest quality parts, assembly and machining techniques, and correct tuning, maximises the performance and gives excellent reliability and longevity.
The correct combination of components that interact well, and suit the car’s weight, gearing and driving style is essential to achieving the desired result. We do not sell parts that we know won’t
work, and neither will we sell anything that we are not capable of installing and tuning.
