Unveiled in 2023 as the successor to the DB11, the Aston Martin DB12 represents a full technological step forward for the platform. Aston Martin calls it the world's first super tourer, and the hardware backs that up: a 4.0-liter twin-turbocharged V8 producing 671 horsepower, a wider track, a completely redesigned interior, and a new infotainment system with Android Auto and Apple CarPlay. The DB12 comes in two body styles, the Coupe and the Volante convertible, with the Volante's eight-layer fabric roof opening in 14 seconds at speeds up to 31 mph. Both share the same 5x128 bolt pattern and factory 21-inch staggered wheel setup, giving aftermarket builders a clean, well-defined fitment baseline to work from. The DB12 S variant, unveiled in late 2025, pushes output to 690 horsepower with revised transmission calibration for faster shifts. Whether you're refining the daily driver or building a show-ready grand tourer, the DB12 platform rewards intentional, well-chosen upgrades.
The DB12 leaves the factory on a sophisticated adaptive damping system tuned for grand touring balance. Running stock suspension, the platform already sits at an aggressive, purposeful ride height with the factory 21-inch staggered setup. For owners who want to preserve the OEM character while upgrading wheels and tires, stock suspension is a fully valid starting point. The factory geometry is precise and the ride height is already low enough to command presence without modification.
A set of progressive-rate lowering springs drops the DB12 a measured amount over the factory dampers, tightening the wheel gap and sharpening the visual stance without a full suspension overhaul. The result is a cleaner, more planted look that suits both the Coupe and Volante. Expect a firmer ride character compared to stock, and confirm spring rates are matched to the DB12's adaptive damper system for best results.
Height-adjustable coilovers give DB12 owners full control over ride height and corner balance, letting you dial in exactly how the car sits. On a platform this precise, adjustable suspension is the enthusiast's tool for getting the wheel-to-arch gap exactly right, whether that means a subtle tuck or a more aggressive drop. Damper adjustability lets you tune the ride for track days, canyon runs, or daily use without committing to a fixed setup.
The DB12's 4.0-liter twin-turbo V8 responds well to improved induction. An aftermarket cold air intake draws cooler, denser air into the turbos, sharpening throttle response and adding a more pronounced induction note under hard acceleration. On a forced-induction engine like this, the intake feeds directly into turbo spool, so the character change is immediate and audible.
A cat-back exhaust system, replacing everything downstream of the catalytic converters while leaving them in place, is the most impactful legal bolt-on for the DB12's sound character. The twin-turbo V8 gains a deeper, more aggressive exhaust note at full throttle while retaining the refined composure at cruise that defines grand touring. Reduced backpressure behind the cats lets the engine breathe more freely through the rev range.
Beyond intake and exhaust, the DB12 platform supports a focused set of bolt-on upgrades including a muffler upgrade for refined sound tuning. For owners running multiple bolt-ons, a supporting ECU calibration optimizes the combination and gets the most out of the changes. Keep modifications legal and emissions-compliant; the DB12 is a road car first, and the best builds respect that.
The DB12's sculpted bodywork and low-slung stance give exterior and interior upgrades a strong foundation, and the right additions sharpen both the visual presence and the ownership experience.
The DB12's LED headlights are already a design statement from the factory, but aftermarket projector and halo retrofit options let owners personalize the front-end signature further. Sequential turn signals and DRL accent upgrades add a modern, dynamic character to the lighting suite. For the show-stance crowd, underglow and interior ambient lighting are natural complements to a car that spends time at events and in garages where every detail gets noticed.
Window tint is one of the most effective exterior upgrades on the DB12, protecting the interior from UV exposure and adding a cleaner, more intentional look to the glasshouse. On the Volante, protecting the fabric roof and interior surfaces from sun and heat is a practical priority alongside the aesthetic. Inside, custom seat covers protect the DB12's leather interior on cars that see regular use, and premium floor liners keep the footwells clean without compromising the cabin's character. These are the details that keep a grand tourer looking and feeling right over time.
Good: Lowering springs over the factory adaptive dampers for a cleaner wheel gap and a more planted stance.

It depends on your goal. If presence and stance are the priority, wheels and tires are the most immediate visual change, and the DB12's factory 21-inch staggered setup gives you a clear fitment baseline to build from. If driving character matters most, suspension is the place to start. Performance bolt-ons like an intake or exhaust are a natural third entry point. There is no single right order; start where your build intent is strongest.
Yes. Get pre-approved before you build your cart so you know your budget going in. Pre-approval is fast and lets you shop with confidence rather than guessing at what fits your spend. Once you know your number, you can put together the right combination of wheels, tires, suspension, or performance upgrades without compromising the build. Financing details are available on our site.
