Product Description
This is a set of upper and lower rod bearings with the WPC surface treatment for E9X M3 S65 V8 engines.We take a standard BMW bearing shell and give it the WPC treatment, a microscopic shot-peening of the bearing -
- Removes high spots and imperfections
- Improves fatigue resistance
- Increase the surface's oil retention abilities for more lubrication
- Safer than a coating and will not decrease clearances
- Preserves the factory bearing's metallurgy
Bearings are sold by size. These are the standard 53.0mm inside diameter size.
Note: connecting rod bolts cannot be re-used. They are stretch-to-yield and must be replaced.
Price is for the set of 16 bearings for the V8.
Engine Oil Note: we strongly recommend a quality oil such as Red Line because of its higher zinc content and better protection values at operating temps. For a dedicated track/race car the Red Line Racing oil has the most zinc and shear strength (but lacks the detergents desirable in street oils). Correct oil operating temperature is 220°F - you should properly warm your engine before subjecting it to higher throttle angles and RPM.
