I've asked you this befor,e but does it physically hurt to be this closed minded? Yore' a retard, pure and simple You don't even know the rudimentary facts behind the vette's composite "leaf" spring and why it works so well.
To repeat what I posted before...
1st... the Corvette uses an extremely lightweight composite monoleaf that is about as high tech as suspension components get. By mounting it on the car in the center of the "leaf," the spring actually carries it's own weight, which is better for suspension response. It weights A LOT LESS than coil springs. One leaf replaces two coils. The two coil springs weigh 3 times as much as the one leaf. Additionally the leaf is placed at the bottom of the car so that in addition to removing weight you lower the CG.
2nd...traditional buggy leave springs were multi leaves and were used as suspension arms as well as springs, which was bad due to being inherently flexible. Plus they had friction as the leaves rubbed against each other. The Corvette's monoleaf only has olne job to do: be a spring. That's what makes it unlike any other leaf spring suspension of old cars.
3rd... you really think coil springs are some sort of new development?
Why doesn't everyone use it?
-Engineers like to stick with what they know. Lots of suspension engineers are familiar with using coil springs. They could experiment with leaves if they wanted or they could stick with coils and get the job done.
-Perception. Just like pushrods, the leaf spring as a stigma attached to it. The reasons for the stigma are legit (a key component to old, heavy and typically poor handling suspension). However the reality is the sum of the older parts was the problem, not a specific part of it. In the older buggy spring type setups (like the rears of older cars) the leaf spring was not just the spring, but all of the suspension. The Corvette is actually a dual A arm suspension that has one half of a high tech composite leaf as the spring, and that's all the leaf does.
Coil race springs are not car specific. You select rates, diameters, length etc but you donít have a specific spring for a specific car. If you want to order a custom spring Hypercoil will wind it to your specifications on the same machine they use for the next custom spring. A custom Porsche, Formula Ford and LMP car spring can all be made on the same machine. By the time the C6 evolves into a C6-R (they donít start off with a production Corvette) the suspension geometry is so different that they couldnít just mount a C6 leaf spring. Itís far too expensive to have a few custom leaf springs tooled up (you would have to buy the tooling as well as the springs) so they use readily available coil springs.
This type of universal tooling isnít available for the composite leaf spring. Only the Vette currently uses the spring so you are making a Vette only part. This seriously reduces the market for aftermarket composite leaf springs (still there are after market leaf springs available for the Vette). The business case for custom equipment to make Vette springs is harder to justify since itís a smaller market.
In reviews, such as between the Corvette and say, Porsche, the reviewers are using the stigma as fact. They still equate the leaf with old style buggy leaf suspension and look for reasons to call it out, even if they have to make up those reasons. The differences in the car's "feel" have nothing to do with the spring material, but with shock/spring rates and with car layout (the Porsche is heavily rear biased, the Corvette is evenly balanced, but heavy). But since the dual A arms of the Corvette have a single composite monoleaf half attached to it at the outer end, those reviewers think that the "stoneage leaf spring suspension" is sub par in comparison,and to blame for the differences in feel. It could be tires and tire pressures. It could be in alignment specs, or A arm geometry, or in the bushings in the steering. Assuming it's the composite monoleaf because you equate it with old style buggy springs is ludicrous, but magazine reviewers will do that. And so did you.
Ignorance colors your perception of the world and you think it's perfectly acceptable to BE ignorant and idiotic.
