GPI L99 Camshaft VVT - SS4 VVT (2010 - 2015 Camaro) - SS4VVT
The Most Aggressive VVT Camshaft for 5th Gen L99 Camaro Builds
The GPI SS4 VVT Camshaft is the top-end, all-out naturally aspirated VVT grind for the 2010 - 2015 Camaro L99. Designed for hardcore street/strip and competition-focused builds, this camshaft delivers massive airflow, exceptional high-RPM stability, and the strongest performance of any VVT-compatible L99 cam in the GPI lineup.
This cam is intended for drivers seeking maximum N/A power while retaining VVT functionality. With proper valvetrain and supporting mods, the SS4 VVT pulls hard to an impressive 7200 RPM and has been track-tested as a proven 10-second capable camshaft in well-prepped 5th Gen Camaro builds.
High-Performance Requirements & Flycutting Information
Due to its aggressive specs, the SS4 VVT requires several key upgrades for safe operation:
- 4000+ RPM stall converter required
- 3.91 gearing strongly recommended
- Flycutting required: Must flycut the intake valve .055" with stock heads and gaskets
If milling the heads or running thinner gaskets, additional clearance adjustments must be made - add milling amount and gasket thickness differences to the required flycut depth.
Track-Proven 10-Second Performance
GPI Cam & Head packages featuring the SS-Series grinds have carried countless L99 Camaros into the 10-second quarter-mile range. The SS4 VVT represents the highest-output VVT option available, delivering exceptional torque and horsepower gains from midrange to very high RPM.
Strong in N/A or Centrifugal Boosted Applications
While intended for aggressive naturally aspirated builds, the SS4 VVT also pairs extremely well with centrifugal superchargers. The cam's linear high-RPM powerband makes it an ideal option for future boosted combinations.
A Four-Cam L99 VVT Lineup
As the top-level cam in GPI's L99 VVT lineup, the SS4 VVT sits above SS1, SS2, and SS3 profiles. It is the go-to choice for L99 owners seeking maximum horsepower while maintaining VVT.
