Cat Cams shim under bucket followers
For Mazda MX-5 B6 and BP engines.
These followers convert hydraulic followers or shim over bucket followers to shim under bucket followers. Shims are liable to pop out at high RPMs. Converting to shim under bucket keeps the shim in place, allowing for reliable operation at RPMS of 8,000RPM and above.
