Bilstein PSS10 (B16) Coilover for the 4C.

This coil-over suspension system for the 4C offers the best of both worlds, increasing the ride compliance of the car while also improving handling!

The Bilstein PSS10 coil-over system allows you to adjust the ride height and firmness of your 4C. The system bolts on in place of the stock suspension parts and allows mild lowering (if desired) or corner weighting for perfect chassis set-up. The shock absorbers feature 10 settings which adjust both compression and rebound - from very compliant when set at 1 to race-car firm when set at 10. Ride height and shock settings can both be adjusted at any time after the system is installed.

For street use I recommend a setting of 2 front/ 3 rear which will deliver fantastic compliance over bumps for those who find the Stock suspension a bit too hard.

Made in Germany of course.

It'll be interesting to see how those coilovers with spring rates of 2.5X of the OEM rates can deliver more compliant ride...
Do you guys know what spring rate range can the bilstein shocks accomodate if one would to start swapping springs?

I have asked Bilstein as no one at this point has swapped the springs out. I will have an answer for you asap. I think you will find once installed and adjusted that you will find a compliant ride you prefer.

Bilstein states +/- 20N/mm is no problem.

CallmeAl put these on his 4C as a first replacement and found the ride to be more sophisticated. He could hit ripple strips and not have the car become unsettled. Ultimately not quite racer enough for him as he went to super wide slicks but more than satisfactory going up one level in tyre grip. See if you can find his posts on them.
