Default would mounting the shocks up side down work

Just thinking out loud here but why don't they mount the shocks up side down? Looks like it would be better to have the weight of the body and oil on the bottom near the tire.

No, you just effectivly increased unsprung weight.

Because you can never get all the air out of the shock, so at full extension youd have the piston out of the oil and that would mix the air into it during compression.

That makes sense. Thanks

Plus, if it was a viable concept, wouldn't one of the major manufacturers already have produced a vehicle designed to have worked that way?

It's been done. A picture of the first RC10 prototype.

Because almost every racer uses upside down shocks rc shocks are upside down type

You can get all the air out if you build your shocks in a vacuum chamber. That being said, if the shocks on your car are not bladder shocks, you need air in them. That is how they are designed. If after your emulsion shocks have been cycled a few times to mix the air into the oil you still have an air pocket, then you need to add oil to the shocks. It is work to keep your cars in good working order. Ever wonder why the fast guys are fast? They keep their cars perfect.

That's what I felt like after reading your post 3 times to figure out what you were trying to say since it wasn't in English.

There is also probably more chance of damaging them upside down I recon. Body of the shock nearer the ground, where all the action is...

I know this is the off-road thread, but ive mounted them upside down on one of my touring cars. It really helped to lower the CG and helped it corner better.

Almost all full size race cars without an inboard push rod suspension use inverted shocks. So it is not uncommon in the full size racing world.

Yeah, except all off-road race vehicles. Like was posted earlier, it has to do with unsprung weight. In any vehicle where the amount of travel is not very much (on-road) the change in the unsprung weight may not be noticeable, but when you start adding weight that has to move a large amount, it negatively effects the handling of the car. Basically most things that people on this forum want to try need to remember is "if you have no idea what you are doing, it is best to copy those of us that do". If you have an idea, and can't believe it hasn't been tried before, you can bet it has, and didn't work as well. The cars now are just refinements of the same design. To see something radically different, that works better than what we have now, we would need a big change in the type of tracks on which we race.
