Lightweight flywheel (Exedy TF02) in GR86

[Jianlun]

Just installed the Exedy TF02 flywheel. Internet says its 12.7lb ie 5.8kg.



Stock is 9.9kg (see photo). NOT the same part number as gen 1. 12342AA180 (gen 2) vs 12310AA403 (gen 1).



Doesnt feel all that much difference to be honest. Driving off/cutch control seems identical (i pair it with stock clutch), doesnt make it any more "stall-able" than stock, slightly more vibrations from the engine when idle.



Screenshot is of me in neutral and clutch in (ignore my non-zero speed), and doing a snap WOT. Exedy TF02 is the lower one.

Did you notice any difference when rev matching downshifting, or just the revs dropping in general?

I notice a little rev hang and throttle delay and I wonder if your lightweight flywheel would affect either.

I drove the before and after a few days apart and i am not a sensitive driver... but for what its worth i say there is slight difference in the rev hang (doesnt hold at high rpm as long after you close throttle) but not enough to cause me to have to adjust any driving style.

Throttle delay wise i actually never felt it being a problem with the stock flywheel so i guess zero difference there.
