NC Sport Suspension Package (Spring Change)?

[Smooth Operator]

Is there an improvement in handling to be had by going to heavier weight springs? Does anyone one know if the Eiback springs are stiffer than the option package? Will the 6K / 5K spring package on the JIC's go on the Blistiens in the optional package? Is there any other options short of the JIC paackage? Thank You, Amoure

Yes

Does anyone one know if the Eiback springs are stiffer than the option package?

Yes. About 30%, which is still far too soft IMO.

Will the 6K / 5K spring package on the JIC's go on the Blistiens in the optional package?

No, unless custom modification

Is there any other options short of the JIC paackage? Thank You, Amoure

Yes. In Japan, there are Tein Flex, Tein Mom Flex, Tuckin99, Ohlins DFV, Bilstein, and a lot more…… All depends on how much you willing to spend. In North America, JIC is the only full coilover package available as of now.

I personally don’t like JIC cause coming from Honda scene, I’ve learned far more negative feedback regarding JIC. In general, 80% of Honda JIC running are not happy. I don’t assume JIC will make much of difference in construction on Mazda application. I guess weight play a big role since none in Honda lineup in the pass 10 years weight as light as NA Miata.

I did some checking around the web. It looks like more choices of coil overs are going to become available this month.

Yes, JIC available now, Eibach coilovers available very soon (shown at SEMA in the MazdaSpeed booth). We will also have our own brand very soon. Bilstein says their PSS9 kits will be coming too....and on and on.

I guess I will try to get the Eibach Pro Spring Kit put in by the Dealer. 30% stiffer and slightly lower roll center. Thanks

There are also some MazdaSpeed coilovers for street use now. From what I've read the spring rates are softer than the JIC's - "80% over stock", which comes out to ~200 lbs in the front, I believe.

Still MUCH more expensive than any of the available seperate shock/spring combos, though.

*edit* I did some more poking around tonight and found both some H&R and Eibach coilovers online. Lots of options out there.
