Background

The BMW M3 has captivated enthusiasts since the original E30, and the E90 series is no exception. Many regard it as the perfect blend of everyday usability and track performance — a true sports car with room for passengers. A well-tuned chassis, robust construction and a high-revving V8 make it an almost-perfect canvas for a track car. Almost. Soaring water and oil temperatures have been one of the few persistent issues with these cars. do88 analysed the causes and engineered a durable solution.

Considerations

The Big Pack is for the driver who pushes the car beyond ordinary use. Ideal for track days, circuit racing, endurance events, or hard street driving where uncompromising stamina is required. Unlike the manual variant, this kit includes a dedicated DKG/DCT transmission oil cooler — critical during sustained downshifts and hard track work. This is one of the longest-developed products in do88's history, and it shows — in fitment precision, finish quality, and track results.

The finished product

With this Big Pack the car can finally be used the way it was designed to be used — without second-guessing the temperature gauges.
