Setting Miata Ride Height
Re: Setting Miata Ride Height
From KW's site:
"The 2-way race shocks are specifically valved for use on the race track, and use a linear spring in all applications."
That's why JY's spring-rate increases as the car get lower. The Xidas that Disney got have the fancy hyperco linear springs, spring-rate won't change no matter how much they are compressed.
Edit: Wait, JY do you have v2s or v3s. The next sentences reads:
"The V3 is valved specifically for maximum street performance. The V3 also uses a progressive spring in some cases."
edit again: Harp you got me confused on linear vs progressive. Progressive springs will increase in rate as it's compressed, linear keeps the same rates.
On another note, AST dropped their contingency for Solo II . Berry! Still wanna buy some MCS credit?!

Re: Setting Miata Ride Height
A progressive spring goes from soft to harder.
Linear springs can be preloaded. This doesn't increase the rate of the spring, but it doe increase the amount of load it takes before it starts compressing. My understanding anyway.
I don't understand how lowering your car would increase rate unless you had progressive springs and were lowering the car without moving the lower spring perch.

I'll probably take you up on that later in the season.
Not sure I'm going to be quite ready for the first autox anyway.

Re: Setting Miata Ride Height
Making a spring lower on the shock doesn't effect the spring rate unless you are pre-loading the spring.
If you are talking lower, as in a 6in spring instead of a 7in spring with the same diameter coil, than the spring rate does change (higher for the shorter spring) This is why cutting springs makes a car's suspension firmer.

Re: Setting Miata Ride Height
this kinda lost me. So, your saying if I get a 500lb spring in a 6in and a 7in long configuration...the shorter one will be stiffer??GaryM wrote:Making a spring lower on the shock doesn't effect the spring rate unless you are pre-loading the spring.

because I think thats not correct.. the coil bind is different..and some cars have to have clearance issues adjusted by bottom perch location.. ( different lengths)
A 500lb/in spring thats non progressive..is just that. school me.

Re: Setting Miata Ride Height
I took it he ment both springs had the same diameter of wire. Shorter length will have a stiffer rate. I don't buy springs acording to the wire diameter tho. I just get the free length, rate and block length (length of spring in coil bind) in the perch diameter needed.
I am confused on the lowering the car increases the spring rate statement. It could mean several things that I could speculate about... If you cut a spring to lower a car it will increase the rate unless it is only dead coils (already in coil bind) that you cut off.

Re: Setting Miata Ride Height
No, a 500 lb spring in 6in is the same as a 500 lb spring in 7in. But... if you were to take the 7in 500lb spring, and cut an inch out of it, it would be stiffer than our previously mentioned 6in 500lb spring.John Brown wrote:this kinda lost me.

Re: Setting Miata Ride Height
Lowering my car does not increase the rate it decreases it. If the spring is loaded at all on the carand you lower the car the spring has less load on it and will travel more which with a load already on it makes it travel less and mine are the variant III coilovers. JY
