Product Description
BMW S58 Pro-H Connecting Rod Set (CARR Bolts) - CP Carrillo SCR15003
When it comes to pushing the BMW S58 engine to its full potential, stock internals quickly become the bottleneck. CP Carrillo’s connecting rods are purpose-built for serious power — engineered to thrive in the extreme heat and high RPM demands of competition-grade turbo builds. Forged from aerospace-grade steel, these rods combine brute strength with precise balance, offering peace of mind at 9500+ RPM and power levels exceeding 2000 hp.

Tech Tip: WMC vs CARR Rod Bolts
WMC bolts are Carrillo’s proprietary high-strength fasteners designed for most performance applications, while CARR bolts are a premium upgrade made from multiphase alloy, offering even greater tensile strength and fatigue resistance for extreme, high-RPM engine builds.
The main difference:
CARR bolts have higher tensile strength and superior fatigue resistance, ideal for extreme high-RPM and high-horsepower use.
WMC bolts are reliable for most performance builds but not as strong as CARR.
In short:
CARR = premium, stronger, for extreme builds
WMC = standard, cost-effective, for most performance use
| Feature | WMC Bolts | CARR Bolts |
|---|---|---|
| Torque Cycles | Typically 3–5 reuses (if stretch is within spec) | Typically up to 10+ reuses (more stable under repeated torqueing) |
| Stretch Stability | Very good | Exceptional – less prone to permanent stretch |
| Torque Retention | High | Higher – superior clamping consistency |
| Ideal Use Case | High-performance builds (street/track) | Max-effort, extreme builds (race, 9500+ RPM, 1500+ HP) |
