up. Expect some chatter with metallic based discs.
- Gearing and tire size have a huge effect on clutch engagement. Taller rear gears (lower numerically) require the clutch to be slipped more on takeoff to get the car moving, and will cause metallic
discs to chatter.
- Check for bent clutch disc. If the transmission does not slide in smoothly on install, or if you have to “rock” the transmission to get it installed, the clutch disc can become bent and cause chatter.
- Using power or air tools to install a pressure plate can distort the mounting flange, causing the clutch to pull down unevenly and create chatter on engagement.
- Worn or broken engine or transmission mounts will amplify a chatter situation. Check them even if they are new. Urethane or solid mounts will also amplify chatter, as they are not able to absorb
this shock.
- Aftermarket bellhousings must be dial indicated to the engine. If the bellhousing is not centered or square the transmission will cock on install and cause the disc to run out, thus causing chatter.
- Flywheels MUST be resurfaced or chatter can occur, especially when changing from an organic based clutch system to a metallic system. Aftermarket flywheels that are unground require surfacing
before use.
Metallic clutch disc tips
Paddle style metallic discs are produced slightly undersized.
An 11-inch disc will measure closer to 10.5 inches. This is intentional and your clutch disc is NOT mispackaged.
Metallic clutch discs can provide greatly increased life over stock organic clutches, however they can be trickier to drive in street applications. Because of the increased aggressiveness of metallics, it
may be necessary to “slip” the clutch more on takeoff to avoid chatter. Using a lighter static pressure clutch or lower gearing will relive the chatter as well as provide a lighter pedal feel.
Metallics are recommended for use only with steel or explosion resistant clutch components. After initial break in, recheck all adjustments.
