in·ter·op·er·a·bil·i·ty

There's been lots of confusion around the actual interoperability of clutches and flywheels between the S65 and S85.

This Clubsport package settles it with a twist.

In this Special Series, I document the unboxing impressions, fitment and how it all feels.

Enjoy,

The pick up point did change. OE clutch used to grab lot sooner as you lifted your foot on the clutch but this clutch grabs really high almost at the end of the clutch travel.

Clutch feels really good in the hills. Specially third to fourth or fourth to third. Acceleration is smooth and more instant getting on the power again.

Lightweight flywheel really helps with the RPMs from falling too fast. With the stock clutch and flywheel during shifts it would drop too quick and I had to put more effort to maintain the car at higher RPM thru the corners just so that I can keep the car within the power band.
