Yup. I'm sure folks will come along with their experiences with the 124 in short order. Well worth trolling Miata.net for suspension discussion when it comes to adding coilovers to this platform. Lots of good tuning info there that applies.
The suspension design is identical between the ND and 124. (The suspension tuning is slightly different.) Coilovers, anti-roll bars, and brake kits made for the ND will fit the 124, but keep in mind that the 124 has a slightly more forward weight bias. You will need to tune your spring rates and sway bars accordingly.
