pressure plate spring also diff, semi race has 3 spring steel, oem only 2 that would give exedy better clamping force.
i had compared the friction plate between trinity clutch and found that exedy has more thicker and without riveted key.
semi race has 6 double springs while oem only 4 single springs. all these spring used to withstand centrifugal force from flywheel. i belief some of racing after markets do not hv this. the rivet also diff.
after installation it will tighly clamp each other. no free play.
hi there,
ReplyDeletethere is a mistake in the blog. the difference between stiffer and normal relies on the diaphragm , malaysia ppl call it kuku or matahari. The side spring steel is to give better distribution of pressure when the diaphram has been made thicker and stiffer.
