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 of our Clutch Plates are thoroughly tested and are currently being used in various racing cars throughout Europe, including track, hill climb, rally and, of course, drifting disciplines.
A MUST HAVE for all regular track afficionados!
*All parts fits OEM Opel (ZF) LSD unit without any modifications.
RacingDiffs Recommends Motul Gear Competition 75w140 oil for all products.
