so just completing my first month of model s ownership (2017 100d)
..... but i would like a bit better roll control and overall firmness.
i'd like people to be aware, however, of installing springs that have not been tuned to the valving of the dampers (and the rest of the car). they'll look great, but performance can be worse than before. i did just this on a 2015 bmw m3 - i wanted the body just a little lower than stock and ordered new springs from a major oem/aftermarket suspension manufacturer. after installing, the car looked awesome and the everyday ride was good, but track performance suffered and i went back to stock just before selling that car.
i know we ("we" being those who want more suspension options) are few in number and that makes us not so appealing for a manufacturer to custom design a suspension solution, but i see three options.
1) set of lowering springs for those who want looks at the potential expense of ride quality
2) springs + matched non-adjustable damper package (would be either firm, medium or soft depending on options) + matching anti-roll bar
3) springs + adjustable damper package (could adjust between soft and firm on the damper itself) + anti-roll bar options
i'd personally love to find or build #3. i think its just a matter of getting the current part numbers to spec the current dampers, springs & arb, map those parts to what ohlins, bilstein, mcs, etc have in stock as replacements, then trial and error til we find what works.
i'm no suspension engineer so i'm open to other alternatives and suggestions. i have done a lot of track time, however, with both adjustable and non-adjustable suspensions and hopefully we can get testing some alternatives shortly.

congrats on the 100d! i'd be interested in option 3 as well but have no idea the cost associated with this. i think unplugged performance may be working on something for model s.
