Hmm in Poland RS is being phased out and TWS Motorsport originally developed for BMW M3 is taking it's place. It's better, that I can say from experience from a number of turbocharged and abused cars.
SRF is just great but absurdly expensive.
I was told by a number of oil people that SAF-X/SAF-XO/SAF-XJ is better for diffs then TAF-X but can't be sure what's best for a Cossie.
