Performance Upgrades

At Charleston Supercar, performance upgrades are approached with the same discipline and attention to detail as factory-level service. Every modification is evaluated as part of a complete system — not a standalone part install — with an emphasis on reliability, drivability, and long-term integrity.

While many of the manufacturers and calibration partners we work with offer defined stage-based upgrade paths, performance work at Charleston Supercar is never treated as a one-size-fits-all package.

Stage-based upgrades can be an excellent starting point when they are applied correctly and supported by the proper hardware, calibration, and vehicle condition. Rather than selling performance strictly by stage level, we evaluate how each upgrade fits the vehicle, the client’s goals, and real-world use.

Our role is to ensure that any stage-based system is implemented correctly, fully supported, and calibrated as part of a complete performance solution — not simply installed in isolation.

Our Performance Philosophy

Modern performance vehicles are complex, highly integrated systems. Power gains, sound, and handling improvements must be matched with proper calibration, supporting hardware, and real-world validation.

Our philosophy is simple:

Performance should feel right, not just look impressive on paper
Reliability and drivability matter as much as peak output
Modifications should complement the vehicle — not fight it

Every performance project begins with a conversation, not a parts list.

How Performance Work Is Handled

All performance upgrades follow a structured, professional process:

Consultation & goals
Street use, track use, sound preference, drivability expectations
Vehicle inspection & baseline evaluation
Mechanical condition, known platform concerns, existing modifications
Parts and system selection
OEM+ and proven aftermarket components matched to the vehicle
Professional installation
Installed to factory-level standards with proper documentation
Calibration & tuning coordination
Performed in collaboration with trusted tuning partners
Post-install validation
Verification, road testing, and final review before delivery

This approach ensures performance upgrades are executed correctly — the first time.

Tuning & Calibration

Charleston Supercar is not a tuning-only facility. All calibration work is coordinated as part of a complete performance system and is performed in partnership with established, reputable tuning providers.

We work with select partners including PTG and M-Engineering, whose calibrations prioritize drivability, safety, and consistency across real-world conditions.

Tuning is never approached as a shortcut or standalone service. Proper calibration is the final step of a well-engineered upgrade path — not the first.

Performance Parts & Hardware

We source performance components from trusted manufacturers and suppliers with proven engineering support and platform-specific validation. Parts are selected based on compatibility, quality, and long-term performance — not trend or hype.

As a wholesale partner with Vivid Racing, we have access to a wide range of high-quality components, allowing us to select the right solution for each vehicle and application.

Common upgrade categories include:

Intake and airflow improvements
Exhaust systems
Cooling and reliability upgrades
Suspension and handling enhancements
Forced-induction systems (vehicle-dependent)

All parts are vetted for fitment and suitability before installation.

Exhaust Systems

For clients seeking a refined sound experience without sacrificing control or build quality, we offer premium exhaust solutions from Valvetronic Designs.

These systems combine exceptional craftsmanship with valved technology, allowing drivers to enjoy an aggressive tone when desired and a more subdued character during normal driving. Sound, aesthetics, and functionality are treated as equally important elements.

(We also offer other exhaust options, see individual links for more information)

Vehicles We Support

Performance upgrades are offered for select platforms where we can confidently support the work to OEM or better standards, including:

Corvette (C6, C7, and C8 platforms)
Aston Martin
Lamborghini
Audi R8
McLaren
Ferrari
Porsche
Select performance and luxury vehicles

Each platform has unique considerations, and services are tailored accordingly. Vehicle-specific performance pages provide additional detail.

Expectations & Guidelines

To ensure quality and consistency:

Performance work requires the vehicle to meet baseline mechanical standards
Customer-supplied tuning files are not accepted
Unverified or incompatible parts may be declined
Additional labor or supporting upgrades may be required depending on vehicle condition

These guidelines allow us to deliver performance upgrades responsibly and professionally.
