There are different types, “S METAL” and “R METAL”, of the EXEDY SINGLE SPORTS SERIES metal discs, but what are their characteristics?
EXEDY has three types of metal discs, S, R, and P. (It may not be available depending on the model of the car)
They are representing the thickness of the metal facing materials, where S represents “thick”, R represents “thin”, and P represents “ultra thin”.
As its characteristics, thinner the disc, inertia of the disc is less, making the operability of the shifting better.
Thicker models have longer life expectancy in general, so select the model depending on your usage and taste.
Following are some references.
Use the EXEDY cover assembly compatible for each when replacing.
