The way i see it, theres probably 3 things that could be contributing to the harsh ride on your car:
* Springs/dampers significantly harder than stock. Both can be made with a large variety of rates. Some aftermarket lowered springs may only be slightly harder than the stock ones, while others might be rock hard. Likewise the dampers. Might be worth having a poke around under the car to look for some brand names or other identification. You mentioned the coils were red which excludes Kings. Maybe someone else has some ideas.
* Suspension travel. The NA's dont have too much suspension travel before they start riding on the bump stops. The solution is to either bolt in NB suspension as Grump as done, trim/cut the bumpstops, or install shorter aftermarket bumpstops.
* Bigger wheels. NA's came standard with 14in wheels/60 profile tyres. Go up to 16 (like yours) or 17in wheels, and the profile reduces to 45/40. Less rubber = harsher ride.
So you could replace the lowered springs with some stock ones, but the shocks and/or wheels may still cause some harshness. And if you're concerned about the visuals, an MX5 with 16in wheels and standard shocks can sometimes look a bit jacked up.
Its also hard to give advice as different people have different thresholds when it comes to judging ride.
In my case, ive got King springs (30mm lower) and 17in wheels on my car at the moment. The low speed ride is acceptable in my view, but the lack of suspension travel is the problem. This is most obvious when you hit a bump while the suspension is already partly compressed (eg when cornering or on an undulating road). The resulting crash can be quite uncomfortable at times, especially as the NA seats are not overly generous in padding.
From what ive read (and this matches Grumps previous comment), you can get a lowered MX5 riding as well as stock. All depends on the brands of shock and springs, sufficient suspension travel, and the size of your wheels. Im hoping thats the case anyway, as im installing some AGX shocks, FCM bumps and NB8A 15in wheels soon.
ps. Love the new car. Always loved the Laguna blue colour.
