Outstanding Customer Reviews 
Castrol ceased production of RR363 back in 2018. As such Flying Spares purchased the remaining stock to ensure we could provide a continuous supply to our customers whilst we sourced an aftermarket alternative. We are now only a few months away from selling our last remaining stock.
No Longer Available
We are pleased to be able to offer an alternative. Our RR363 has been developed by a leading brake fluid manufacturer. Whilst adhering to the original formula we have been able to demonstrate that our RR363 produces lower rubber swell and achieves a higher boiling point.
Flying Spares is committed to ensuring that we continue to offer you the widest choice of parts at the best possible prices.
