Just upgraded from OEM DMF (12,68kg) clutch kit to performance light SMF (7,2kg) clutch kit. It was a must after 85.000km under APR stage 1 (316HP & 516Nm).
Tested...and I love it! Numbering advantages wold take time, more of it in detail soon. For the time being, let me mention the only downside, literally: I need to rev engine just a little bit higher, in order to start smoothly. Let's say 1.200rpm - 1.500rpm.
Yes, somewhere outside town in quiet winter landscape discreet shatter can be heard:
From the outside in neutral.
Barely from the inside only when pressing gas pedal in neutral within 750rpm to 1.000 rpm range, beyond that and while in idle: nothing. In total.
I feel like I am driving another, much better car.
Looking forward hearing about your experience with OEM DMF vs after market Light SMF.
