do88 BMW M3 (E90/E92/E93) BigPack

Ever since the first E30, the BMW M3 has enchanted enthusiasts around the world, and the E90 generation is no exception, widely considered the perfect combination of usability and performance. With its well-balanced chassis, thorough construction, and hefty S65 V8, it's almost the perfect base for a race car. But only almost, ascending liquid temperatures across the engine, transmission, and power steering systems are among the platform's few known issues. do88 analysed the reasons behind this and developed a genuine, comprehensive solution.

Rather than piecing together individual components, the BigPack brings together do88's entire cooling range for the E9X M3 in one coordinated purchase, all with genuine drop-in fitment using OEM oil lines, brackets, and mounting points. This is one of the most man-hours-intensive product ranges in do88's history, reflected clearly in the fitment, finish, and performance across every component. Developed and extensively tested in conjunction with a German racing team, this kit is ideal for both the clubman racer and track day enthusiast wanting maximum performance from their M3 while protecting it from overheating.
