Man, there is some great information here.

Man ........**** That

you can never get me to put 4 wheel shape bombs on my car

hell no

What about titanium, its light and strong?

And very expensive

There's a few companies making carbon / kevlar / hybrid composite wheels - still pretty expensive though

Best bang for your buck is still 2 or 3 piece forged aluminum

The real reason is because the closer the rotating mass is towards the center, the less work the drivetrain has to do to move it. You find this practiced a lot in low HP lightweight cars, such as the Miata.

For example, if you take a weight and attach it to a rope, then swing it while rotating 3 ft from your body. Then swing it 10 feet from your body. How fast are you able to move? How much work is it? Its the same weight right?

Thats the theory behind a smaller wheel/ or even a smaller tire diameter.

This is the answer I was waiting for. You can keep the same weight wheel but in a smaller diameter and have more hp to the ground, just get a taller side wall tire to compensate.

Now this is just funny!!!

Titanium isn't that light...it is nearly twice as heavy as Aluminum. It is just very strong so it can be machined very thin and keep it's strength.

zebra · 11-14-2008, 02:10 PM

depending on if they fit over the brakes, i'm wanting to put 18"s or 19"s on my SS.

Sharpe · 11-14-2008, 06:51 PM

Are 20" the smallest you can get on a new Camaro? You can't get 18"?

A+

Also why it's more brittle and prone to cracking - high tensile strength and less material

I've been looking at Forgeline's Lightwieght ZX3R: I want to go with a 19x10.5 with 305/30-19 Bridgestone RE-11's all the way around. Pedder's Zeta II Camaro runs pretty dang good on the track with them. Better handling, braking and acceleration. Lightens the unsprung wieght by 34lbs. So that's approx. 204 lbs of sprung wieght if you do the math. I personally think the 20's are way too big for the Camaro. I don't know why anyone would want SUV wheels on a sports car. I guess that's what is "IN" however it makes no sense. But that's probably how GM went bankrupt by doing things that make no sense.

M6HuggerSS · 01-30-2011, 11:23 PM

damn you must have been digging for this thread!
this one started back in 2008.

good info!

im with you... id love to get the same set-up as the pedders car.
the car looks much better with 19's and a 1.25" drop.

Nine Ball · 01-30-2011, 11:24 PM

Eric, I can help you with the Forgeline dream.

That being said, the generalized wheel weight savings type math isn't that simple. You can't just use the scale weight of a wheel, you'd need to know its mass relative to the distance from the center of the wheel. Moment of inertia. More weight further out is always a bad thing. Some wheels have heavy hoops (cast wheels, typically), some have very heavy spokes, some are thicker in the hub areas. You could have three different wheels that weigh identical, with different diameters, and they could all have different effects on performance.

8:1 rotating vs static relationship is pretty inflated. It is typically in the 2:1 or 3:1 relationship for wheels.

M6HuggerSS · 01-30-2011, 11:28 PM

nine ball,

do you have the cost and wheel weights of those ZX3R's 19x10.5?

or is there anything that you would concider equal in performance/looks but maybe a better value?
