🔥 BMW M2 Competition S55 – Preventative Maintenance & Performance Upgrades 🔥
This week at JD Garage & Performance Centre we have had a BMW M2 Competition for some preventative maintenance on the S55 platform – rod bearing replacement and a 4-pin crank hub.
During inspection, the original bearings showed clear signs of wear, highlighting exactly why these engines should not be ignored as mileage increases. Left unchecked, bearing wear can lead to catastrophic engine failure and a very expensive repair bill.
✅ ACL Race Bearings Installed
✅ ARP Rod Bolts Fitted
✅ Insane Performance Crank Hub Solution Installed
✅ Full inspection
✅ Fresh oil and filter service completed
The S55 engine is an incredible performance unit, but rod bearing wear and crank hub slip are two well-known concerns. By upgrading to ACL Race Bearings and ARP hardware, alongside the renowned Insane Performance crank hub solution, this M2 is now far better protected for spirited road use, track days, and future performance modifications.
The removed bearings tell their own story – visible wear is already present despite no major symptoms being reported by the owner. Prevention is always cheaper than cure.
If you own an:
🔹 BMW M2 Competition
🔹 BMW M3 F80
🔹 BMW M4 F82/F83
🔹 Any S55-powered BMW
