Coated Bearings: Connecting Rod Bearings for Porsche M96 M97 2.5-3.8 engine in Boxster Cayman 996 and 997 (Set of 12)

Calico CT-1 coated original Porsche rod bearing (STD) for 1997-2008 Porsche Boxster, Cayman and 911 models with the M96 and M97 engines (2.5, 2.7, 3.2, 3.4, 3.6, 3.8). Including 12 coated bearing shells.

Bearings are coated with Calico Coating's CT-1 is a Dry Film Lubricant coating that helps reduce friction and abrasive wear. It provides intermittent dry lubrication and is unaffected by dust or dirt. CT-1 has been specially designed to withstand the extreme conditions of modern high-performance engines. Professional engine builders enjoy a higher level of confidence with improved containment, strength and durability.

Process

We start with genuine Porsche bearings and then the CT-1 Dry Film Lubricant coating is applied as a spray process. Prior to the coating process, different surface preparation methods are used that are suitable for the substrate. The layer thickness is adapted to the application. Typical film thickness for motor bearings is 0,00025″ to 0,00030″ inch (6 to 7,5 microns).

Benefits

Provides intermittent dry lubrication, unaffected by dust or dirt, low coefficient of friction, increases load bearing capacity, thin coating to accommodate mounting restrictions, chemical resistance, corrosion protection, reduced friction and drag resulting in reduced parasitic load. Benefits include:

• Protection against corrosion
• Increased smoothness
• Low coefficient of friction
• Oil and fuel resistant

We only use genuine Porsche bearings and do not offer oversized or undersized bearings for the M96/M97 engine as the components are not designed to be modified. Bars with cracked cap technology cannot be modified - replacement is required if they are out of spec or out of working tolerance. The same goes for the crankshaft - if the journals are scored or blued, the crankshaft is affected. Grinding the crankshaft for undersized bearings will weaken the crankshaft and also cut through the heat treatment, resulting in a much weaker crankshaft. Again, replacement is the only safe option if your crankshaft is damaged, otherwise you will likely experience another failure from using an already compromised part that is being reused.
