The Chevy SS Sedan, a rare blend of luxury and raw power, made its mark from 2014 to 2016 as a rear-wheel-drive performance sedan rooted in the Australian Holden VF Commodore. Packing a 6.2L LS3 V8 engine that delivers 400 horsepower, it’s a favorite among enthusiasts seeking to elevate its performance. For those looking to transform their SS Sedan into a track-ready machine or a street monster, aftermarket upgrades offer significant gains. Here’s a breakdown of key performance parts to consider.
Engine Enhancements
The heart of the SS Sedan is its LS3 V8. To unlock more power, start with a cold air intake (e.g., AFE Power or K&N) to increase airflow. Pair this with high-flow catalytic converters or an X-pipe to reduce exhaust backpressure. For serious horsepower jumps, consider a supercharger (Magnuson or Whipple) or forced induction systems, which can push output beyond 600 horsepower. Don’t forget an ECU tune to optimize fuel mapping and unlock the full potential of these upgrades.
Exhaust Systems
The stock exhaust, while adequate, can be restrictive. Upgrading to a cat-back system from brands like Borla, Axon, or MBRP enhances flow and unleashes a deeper, more aggressive sound. For maximum performance, opt for stainless steel components and high-flow cats to minimize restrictions and improve throttle response.
Suspension Upgrades
The SS Sedan’s factory suspension is sport-tuned, but enthusiasts often seek sharper handling. Coilover systems (KW V3, Eibach) allow adjustable ride height and damping. Sway bars from Whiteline reduce body roll, while polyurethane bushings enhance stability. These changes improve cornering grip and reduce dive during braking.
Brake System Overhauls
Big power demands big brakes. The stock brakes are capable, but track or spirited driving benefits from upgraded kits (Brembo, Wilwood) featuring larger rotors and multi-piston calipers. Slotted or drilled rotors aid heat dissipation, reducing fade during prolonged use.
Wheels and Tires
Lightweight wheels (e.g., Forgeline, SSR) reduce unsprung weight, improving acceleration and handling. Pair with high-performance tires like Michelin Pilot Super Sports or Toyo R888R for maximum grip. A common setup is 19-inch wheels with 265/35R19 tires for a balance of form and function.
Interior and Tech
For the interior, consider performance seats (Recaro) for better support. Add standalone gauges (AEM, Boost) to monitor vital metrics. Upgraded paddle shifters or a short shifter can enhance the driving experience. A tuned ECU ensures all mechanical upgrades work in harmony.
Final Considerations
When modifying, prioritize quality and compatibility. Professional installation and tuning are crucial, especially for forced induction or exhaust changes. Joining SS Sedan communities or forums can provide valuable insights and support. Remember, modifications should balance streetability with performance goals—whether you’re chasing lap times or weekend cruises.
With the right performance parts, the Chevy SS Sedan transforms into a formidable machine, blending daily comfort with track-ready aggression. For enthusiasts, the possibilities are endless, making it a canvas for personal expression and performance artistry.
