There are 2 different variations of this set:
1. Service pack
2. Performance upgrade set:
Clutches are perforated for better cooling and great viscosity to resist the oil build-up in the holes between dog ear plates.
It is well known that drilled brake discs improve cooling over solid discs! It is the same with the LSD clutch discs.
*All parts fits OEM Porsche (ZF) LSD unit without any modifications.
