As the world leader in BMW performance cooling, CSF has taken the lead in introducing a full-line of competition-grade cooling products and complete packages for the B58 engine (found in the Toyota Supra and many BMW G-Series models).
As more vehicles start to become raced in competitive motorsports, the glaring overheating issues that plague this platform have become even more apparent. CSF has answered the call with the release of new exclusive Dual-Core ZF 8HP Transmission Oil Cooler.
CSF is the world leader in BMW transmission cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions – from road racing to the drag strip. During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with our industry-leading transmission cooler for the A90/91 Supra and BMW G-Series’ ZF 8HP transmission. Installed in the world’s fastest A90 Supra – Titan Motorsports Drag Race Supra (first and only Supra to reach the 8s in the 1/4 mile).
