Black Diamond

Any have any insight on the Black Diamond 5th Coil, RR setup? Hearing some rumors, they are going on a tear lately with some drivers

[FlatTire]

They must have not told Terry Phillips.

They trying something like them new items from Advance Racing Shocks? Look on there website.

Dual RR spring, spring inside a spring on the RR, looks interesting. Then they have a fifth coil set up, its like a stack but works different than a normal stack.

Best thing to.do.wpuld be to call stuckey and ask for b.j. or if you have a relationship with Kirk Loudy with Envy Suspension, he's very familiar with the cars. But isn't about giving free info.

Like Punisher88 said, make a call to Ronnie. There are some things we have to keep among ourselves. It's no different than any other chassis builders. Some of these secrets is what give us an edge for a while. Some of us don't mind answering questions but being "that" technical on an open forum aint happening.

I bet its one of them new stretchy chains...LOL

This isn't the air damper over the spring. I"ll wait see if I can see it up close.Just curious if anyone was hearing anything. Its on a car down here in NC but no way I'll be getting close to it lol

This is a screen shot from advance

Sorry tried but it won't upload go to advance suspension and new products

Funny we run this deal on asphalt, crazy how it bleeds over. The preloaded soft spring acts stiffer until you reach your preload number..

Isn't this basically just giving you a way to increase the static load on a corner without changing the ride height or "rate" of the corner?
This has obviously been done before but I think I like the design of the ARS piece a little better than others I have seen (Joe's, Port City, etc.).

Advance has a pretty cool looking 5th coil deal as well, supposed to offer an initial stiffer rate and then get softer for the straight aways.

I was hearing awhile back that Longhorn was taking a softer spring, and preloading it on a smasher to get ride height numbers, not sure the rates and numbers thou.

krom , i remember that fifth coil being discussed on here a while back and i drew up a sketch of some thing very similar , i like the idea of it , but haven't tried it , any one know how much that unit cost????

[Kromulous]

Would like to know myself, seems like a solid theory, with all the aero work that goes on to keep the spolier propped way up keeping the car hooked up all the way down the chute any way possible would be a good thing.

So the way it works.... is the one bottom spring pre loaded heavily, so initially it works the top spring until the force exceeds the pre load in the bottom one, and then they begin to act like a stacked spring past that point? I think that’s what it looks like anyways.
