Updated June 7, 2021 -  In stock and shipping.  Limited availability for the season.

Due to continuing product availability limitations, we recommend planning for this and future race seasons. 

After trying others, we still feel Castrol SRF is the ultimate racing brake fluid for wet and humid conditions.
The unique silicon ester technology absorbs less water than conventional glycol ether fluids and prevents the fluid's high-temperature performance from deteriorating. The high boiling point, ability to withstand extreme temperatures and superior resistance to the effects of absorbed water have established Castrol SRF Brake Fluid as the premier fluid for the hydraulic brakes used in all forms of motorsport and racing.

For the MINI John Cooper Works GP (F56), BMW recommends the use of high-performance brake fluid (Castrol SRF) if the vehicle is driven on a race track.  

Please review Castrol's SRF sheet for additional information.
