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 chassi, its thorough construction and hefty V8, this is almost the perfect core for a race car. But only almost. Wider wheels with sticky R-tires are giving the servo oil cooler a tough job. The heat soak from turning rapidly will affect steering ability and take away sharpness from the steering. This is the solution for your vehicle! This is the product for the experienced driver demanding nothing but the best! It´s suitable for track racing, endurance racing, track days or inspired street usage, where there´s no room for compromise in terms of perseverance. This is one of the products in the history of do88 that has taken the most man hours to develop, which is clearly shown in the fitment, finish and performance. Greater core volume, bigger active cooling area, that frankly is what actually cools the oil, excellent fitment and - of course - vastly enhanced performance, makes us guarantee you will be satisfied!
