Heal toe makes driving fun, I'm not missing the new car paddle shifting nanny experience.

Lightened flywheel will make the engine more responsive and less lazy when you you rev it.
With a lighter flywheel it does helps on track with the heal and toe downshifts.

A Nascar has a 5 inch clutch, my IMSA race car has a 7 inch clutch.
The engine revs up quick on a heal and toe as it has to be as the transmission has dog rings (no syncros) and downshifts are quick as there is no syncro drag as you move the shift lever.

In SCCA in the production GT classes the production corvettes are allowed to reprogram the brain to provide better throttle response.
Makes heal toe more efficient even with the stock synchro transmission.

Back in my VW days a lightened flywheel made your 100hp engine feel much more responsive.

I have a stock 3.2 with a stock flywheel.
What it does best is at idle you can engage the clutch and not stall.

Agree painful to performance drive and heal toe with a lazy revving engine.
For years I had 2 911 cars, one stock and one was modified with a light flywheel.
Both were easy to drive and had no trouble crawling up my steep driveway.

Listen to my old 3.6 with a lighter flywheel on the heal toe downshifts.
It revs quick enough sometimes I have to rev it twice on the downshift because the 915 syncros require a slower shift.


My ultimate is a dog ring box, 730 hp with the light 7 inch flywheel.
Shift lever has no resistance and the engine can keep up with the quick shifting.
Most the clutch wear happens in the pits trying to get the car to roll.
A little clutch slip and some bucking from having a first gear good to 60+mph.


In drag racing the inertia of a heavy flywheel can be helpful when you drop the clutch at the start.
