Croustibat is an unknown quantity at this point

Saving weight from rotating parts, like wheels driveshafts rotors flywheels crankshafts rods piston ring drag accessories/pulleys is a great way to free up horsepower and increase fuel economy. It counts for more when you take it from rotating parts, then when you simply remove it from the dead weight. I would rather reduce my flywheel weight by 10lbs than remove 20lbs of spare tire/sound deaden.
Blah blah blah, i already told you an infinite number of times that you suck at real life thinking. Theory ? I live in real world. Theory gives an estimate to point people in the right direction.

But Practice tells people theories are often wrong because of a simple, overlooked detail. The overlooked detail here is the tyre, which has a limited traction. The very same reason a heavy flywheel makes an engine easy to control, heavy wheels and tyres make a chassis easier to accelerate and brake to the limits.

What i know so far is that removing 16lbs on each corner or my car did not increase fuel economy by a noticeable amount. Really. No change at all. My flywheel went from 24lbs to 10. Nothing either.

It did not improve my acceleration times, nor did it decrease my braking distance.

Quite the opposite actually. Because of the removed inertia, locking the wheels / spinning the wheels happens more. Wheel inertia is the friend of every lead foot driver. And we dont drive formula 1 cars here, these are 20 year old worn S chassis. Not precision tools. They are meant to be driven by burying these pedals. No delicate driving.

Now if you really are a good driver, have a very good pedal feeling and control, and an absolute need to improve your times, then by all mean reduce wheel inertia.

But If you are not ? Forget it. Driving will just be harder.
