Ever since the first E30 series came along, BMW M3 has enchanted car enthusiasts around the world. The E90 series, that has been with us a few years, is no exception. By many elected the perfect combination of usability and performance. A real sports car, with room for passengers. With its well balanced chassis, its thorough construction and hefty V8, this is almost the perfect core for a race car. But only almost. Ascending liquid temperatures is one of few known issues with them. Do88 has analysed the reasons behind this, and developed a sustainable solution.
