How is it an 'all metric honda ng'? I use Imperial measurements for my daily
usage, always have and always will. I was just pointing out his lack of a
decimal point.

635 kg * 2.2 lbs/kg = 1397 lbs. (TI-55 calculator converts it to 1399.9)
Truly light-weight, hi-performance wheels!

Boy, this takes me back to the 60s....

Ride and suspension conformance to the road surface both improve as the
ratio of sprung to unsprung weight increases. Within the load limits of the
suspension, more weight in the trunk smooths the ride and helps hold the
tires on the pavement over bumps. Think of it as: the road makes your wheels
bounce and your wheels make your car bounce. The lighter the wheels the
poorer the energy transfer from the road interface to the car.

The emphasis on the unsprung weight is that it is easier to make a
difference, at least starting with stock. Aggressive selection of wheels and
tires can reduce unsprung weight by 50%. Increasing the sprung weight 100%
(same doubling of the ratio) is not likely to improve your handling and
ride! 60 lbs in a 3000 lb car is 2% difference, so the tool box won't make
the Honda ride like a Cadillac.

Bicycling enthusiasts are even more rabid, since spinning the wheel mass up
takes some leg power. The mantra is "an ounce on the wheel is worth a pound
on the frame." I don't know just how true that is, but you get the idea.

Ah - I was worried about you -- you DO have a sense of humor!

thanks mike.

Theyre 13lbs. 77lbs would weigh a ton on a honda civic..theyre lightweight.

Wow. From all the other physics discussions I've read, I can only
say "it depends".

A lighter wheel has less mass when it bounces and if it was not
opposed by the springs or dampeners, yes, it would bounce more, and
that would be bad from many standpoints.

But the springs oppose this action, and they don't have to compress
as much to do so with a lighter wheel.

Now ideally ALL the components of a suspension system should be
matched and tuned. The spring rate and shocks would match the tires,
which would match the style of driving, the vehicle load, and so on.
There's nothing about it that's cut and dried as far as I can tell.

Rotational mass can be very important, and it all depends on where
you start. Bicycle riders don't produce much torque compared to a
four cylinder engine, and so they're right to be rabid about it.

Four cylinder engines generally don't produce the torque of six or
eight cylinder engines, and so rotational mass makes more of a
difference.

Miata owners are very keen to control and reduce the weights of their
wheels because their cars are light and by all their accounts the
difference will be quite large.

In a few weeks I hope to have some lighter wheels on my 4Cyl LX, and
then I'll know for sure whether it makes any difference, at least for
me.
