Get yourself on the 4C forum. You will find tons of answers there. 4C is awesome.
Cruise control is a good feature, I use mine all the time.
My car has the “sport” not track suspension. Agreed, the track is…track. If your car is too twitchy, replace your tires if it has original p-zeros, use 215 and 245 tires at stock aspect ratios and have a top alignment shop set your car at zero toe. These cars are really, really sensitive to alignment, they run very little caster in general and stock alignment is also toe out. The 205 pzeros are very narrow in the front, so tire stretch and stock alignment settings make the car very twitchy on a rough road with track suspension. My 2020 is very well behaved on back roads, completely stock. You can convert to adjustable Bilstein coilovers which have very good real road settings and sometimes on the 4C forum you can ask if anybody has a set of sport springs and dampers that were take-offs. Many cars have been modified with aftermarket alignment block the enable more camber and caster. Do you have any records from prior owner?
most 4C were ordered by dealers with track suspensions, only about 20% are sport. Kinda being recognized now that this might not be the best approach for many drivers that rarely track their cars. Likewise for 17/18” wheel combo. I will be switching to those for the winter with some Michelin Pilot Sport 4 all seasons.
Get to the 4C forum and you will find tons of answers and a great, active group of members. Somebody there can probably help with the cruise control question.
