ZR1 LS9 Flywheel

[LXSS350]

Anyone know an accurate pedestal mounting height for the OEM LS9 Flywheel as measured from the flywheels clutch plate face? Running the ZR1 OEM clutch kit and I am machining up a 6061 T6 flywheel for a non chev/gm engine.

Now sorted.

FYI for those who are looking at doing an LS9/LS/LSX/LSA/ and even the new LT1 (gen5) conversion and want to use the excellent oem ZF-Sachs twin-plate clutch kit from the C6 ZR1 - some good news. I talked to Dan @ Fidanza and they will be offering a 6061 T6 Aluminum Flywheel in 6 bolt, 8 bolt and 9 bolt versions for the multitude of common GM engine swaps.

Any time frame on the Fidanza flywheels?

Is the CTS-V and ZR1 clutch the same?

No. They are both dual disk, but the LSA clutch is smaller in diameter and uses a dual mass flywheel, while the ZR1 uses a single mass flywheel.

Vastly different the ZR1 is made by ZF-Sachs and can handle around 850ft-lbs.
