Classic cars hold a timeless appeal—whether it’s the sleek lines of a 1967 Mustang or the elegant curves of a 1957 Chevy Bel Air, they represent history, craftsmanship and nostalgia. But while their aesthetics may be unmatched, driving a classic car today comes with challenges in comfort, performance and safety. Fortunately, modern upgrades can enhance your vintage ride without compromising its original charm.
We spoke with Rich McClellan, owner of Elite Customs in Tennessee, to get expert insights on modernizing classic cars with restraint. “The key is balance,” he says. You want to enhance the driving experience while preserving the character that makes a classic car special.”
What is Restomod?
There’s even a new niche market focusing on modern classic car upgrades. Restomod, a blend of “restoration” and “modification,” refers to upgrading classic cars with modern technology while preserving their vintage aesthetics. This approach enhances performance, safety and comfort—such as installing fuel injection, disc brakes and modern suspension—without compromising the car’s original charm. Restomods offer the best of both worlds: timeless style with today’s reliability and drivability.
1. Upgrade to a Modern Braking System
One of the most critical safety upgrades for classic cars is improving the brakes. Many older vehicles come with drum brakes, which fade under heavy use and lack the stopping power of modern systems.
Upgrade Options:
- Disc brake conversion kits – A front disc brake swap significantly improves stopping power.
- Hydroboost brake system – Provides modern braking performance with less pedal effort.
- Stainless steel brake lines – Reduces flex and improves brake response.
Rich’s Take: “Brakes are one of the most noticeable improvements you can make. Disc brakes enhance safety and give you the confidence to drive your classic more often.”
2. Improve Handling with Suspension Upgrades
Older cars often have soft suspensions that were never designed for today’s road conditions. Upgrading your suspension improves ride quality, handling and overall comfort.
Popular Upgrades:
- Coilover suspension kits – Adjustable for ride height and stiffness.
- Sway bars – Reduces body roll in corners.
- Power steering conversion – Makes maneuvering much easier.
If your car has a custom stance or aftermarket wheels, proper suspension tuning is essential to ensure a comfortable ride without sacrificing looks.
3. Modernize the Engine for Reliability & Performance
While carburetors have a vintage appeal, they require constant tuning. Switching to fuel injection can drastically improve performance, fuel efficiency and reliability.
Smart Engine Upgrades:
- Electronic fuel injection (EFI) – Eliminates carburetor issues and improves cold starts.
- Ignition system upgrade – Swapping out old distributors for electronic ignition ensures consistent performance.
- Electric fans & aluminum radiators – Prevent overheating, a common issue in classic cars.
4. Enhance Comfort with Interior Upgrades
Classic cars often lack modern conveniences like air conditioning, soundproofing and ergonomic seating. The right upgrades can make your ride more enjoyable for daily use or road trips.
Interior Enhancements:
- Retro-styled digital gauges – Maintain a vintage look with modern readability.
- Sound-deadening materials – Reduces road noise for a quieter cabin.
- Upgraded seats with lumbar support – Keeps long drives comfortable.
Rich’s Advice: “If you’re driving your classic car regularly, creature comforts matter. Modern soundproofing and better seats can make a huge difference without ruining the vintage look.”
5. Upgrade the Lighting for Safety & Visibility
Dim, factory halogen headlights in classic cars can be a safety hazard. Fortunately, LED and HID conversion kits dramatically improve without changing the classic look.
Lighting Enhancements:
- LED headlights with classic housings – Better visibility without looking out of place.
- Sequential LED taillights – Improves visibility for other drivers.
- Interior LED lighting – Brighter and more energy-efficient.
6. Install a Modern Sound System Without Cutting the Dash
Many classic car owners hesitate to add a modern audio system because they don’t want to cut into the dashboard. The good news? Hidden audio solutions let you enjoy great sound without modifying the original interior.
Audio Solutions:
- Bluetooth-enabled retro radios – Classic look with modern tech.
- Under-seat or trunk-mounted subwoofers – Add depth to your music without visible modifications.
- Door speaker upgrades – Discreet, high-quality audio improvement.
7. Convert to Modern Wheels & Tires for Better Handling
Classic cars were built with bias-ply tires, which don’t offer the grip and ride comfort of today’s radial tires. Upgrading to performance radials improves handling, safety and longevity.
Things to Consider:
- Period-correct wheels – Maintain the vintage style with modern materials.
- Larger-diameter rims with low-profile tires – For a pro-touring look.
- Tire compound upgrades – Modern rubber technology means better traction.
8. Add Power Locks and Keyless Entry
Many classic cars still rely on manual locks and ignition switches. Upgrading to keyless entry and push-button start adds security and convenience.
Smart Tech Upgrades:
- Power window conversions – Keep a clean factory look with hidden switches.
- Remote start – Great for warming up your ride before hitting the road.
- GPS tracking systems – Protect against theft while staying discreet.
9. Preserve the Exterior with a Ceramic Coating
Classic car paint jobs require extra care to maintain their shine. Ceramic coatings provide long-term paint protection from UV damage, bird droppings and environmental contaminants.
Why It’s Worth It:
- Hydrophobic properties – Repels water, reducing streaks and water spots.
- Deep shine enhancement – Keeps paint looking fresh longer.
- Easier cleaning – Less need for waxing.
Rich’s Take: “A high-quality ceramic coating is one of the best investments for a classic car owner. It protects the paint and makes maintenance so much easier.”
Keep the Classic Spirit Alive
Modernizing a classic car doesn’t mean sacrificing its vintage charm. With the right upgrades, you can improve safety, comfort and performance while staying true to the car’s original character
