When it comes to transforming a classic car into a corner-carving, road-gripping, modern-handling machine, few upgrades make as dramatic an impact as a true Pro-Touring suspension package. Classic Performance Products (CPP) created the PTK Series, Pro-Touring Kits to give builders, restorers, and weekend cruisers a complete, bolt-on path to modern performance without sacrificing the soul of their vintage ride. Whether you’re dialing in a ’60s muscle car, a Tri-Five Chevy, or a street-driven track toy, the CPP PTK lineup is engineered to deliver the stance, control, and confidence today’s drivers demand.
What Makes PTK the Go-To System for Pro-Touring Builds?
The PTK line isn’t just a pile of parts — it’s a curated, stage-based system designed to grow with your build. CPP structured the lineup so customers can start simple, upgrade gradually, or jump straight into a full modernized suspension and braking overhaul.Stage I – Better Geometry, Better Feel
PTK Stage I kits introduce the core foundation of modern handling:
- Tubular upper & lower control arms
- Upgraded coil springs
- Front & rear sway bars
- Fresh bushings and improved alignment capability
- This stage alone instantly tightens steering feel, reduces body roll, and preps your chassis for future performance upgrades.
Stage II – Level Up Your Shock and Spring Game
Stepping into Stage II moves your build closer to a true pro-touring setup by adding:
- CPP dual-adjustable shocks
- Lowered performance springs
- Fine-tuning flexibility to dial in ride height and responsiveness
This is where your classic starts feeling planted, composed, and sharp on turn-in.
Stage III – Coil-Over Control
Stage III adds:
- Full coil-over conversion
- Ride-height adjustability
- Improved spring rates
- Better rebound & compression control
Stage IV – Big Brakes, Big Confidence
If you’re adding horsepower, you need stopping power to match. PTK Stage IV includes:
- 11" performance disc brake upgrades
- Optional 13" / 12" Big Brake kits
- Vented, drilled, or slotted rotor options
- High-performance calipers
