You can find specs on the stock spring rates for past generations, so I figure it's only a matter of time until we know what the ND has.

Actually, I went back and checked that thread: http://forum.miata.net/vb/showpost.p...3&postcount=71

The Sport (and presumably GT) rates were measured at 156/80, and the Club at 150/100, and I assume that's lb/in. The measurements were taken by two different people with probably different equipment, so likely the front rates are the same and it's the rears that have gotten 20% stiffer or thereabouts. That makes sense given Mazda's commentary that they changed the springs instead of the rear sway bar.



I would be more inclined to agree if there were a major difference. Maybe the Bilsteins are that much better than the base (heh, I almost wrote "stock" there ) shocks, I dunno. I wouldn't mind being proven wrong if ever a journalist decides to test both, might make my decision of which trim to get a little easier.

Sorry, what I meant was you're most likely not going to get shock dynos from the base dampers to Clubsport dampers.

The 20% increase in rear spring rate is dynamically significant in that it was probably added to balance the handling of what was likely an initially understeering base MX-5 (assuming that the base MX-5 was setup to initially understeer as most road cars are). This would make the Miata feel more crisp on it's turn in and also more controllable with just the throttle. All base 86's now share this handling trait (minor initial understeer) since the FR-S was matched to the BRZ rates in 2014. This initial understeer is considered more safe on the street, but less desirable for spirited driving. It can be dialed out in many ways adding front end mechanical grip is one. Todd noted this when speaking about some of the advantages of the MPSS tire upgrade on his FR-S.
