Tried. Tested. Perfected. ✔️
We went all in to find the ultimate setup for this F90 M5.

Tried five different sets of shocks:
• Bilstein B6
• Bilstein B8
• Pre-LCI Competition shocks
• Standard M5 (non-Competition) shocks
• And finally landed on LCI Competition shocks

Paired with Eibach springs, and we adapted the software to match the LCI Competition setup — achieving the perfect balance of comfort, control, and response.

Every test was worth it — this setup delivers serious results.
