It's pretty well documented in this forum that there were changes in the suspension from Pre-LCI to LCI via coding to the EDC. Also, the Pre-LCI received a software update that made the ride way more compliant.

However, it was also noted by Kevin_The_Clean1 that the spring part #'s are different between Pre-LCI vs LCI.

22 X3M LCI
Rear Spring: 33-53-8-097-252

20 X3M
Rear Spring: 31-33-8-090-598

Does anyone know if the spring rates changed? Or, was it just a part # change? Are the shock part #s the same or different?

I know that the aftermarket springs for Pre-LCI will fit the LCI but is it matched to the LCI shocks?

Does anyone have experience with Eibach Pro-Kit and LCI? I am leaning towards this product as they claim the springs are softer; 12% front & 5% rear.
