Launched for 2010 on GM's long-wheelbase Epsilon II platform, the second-generation Buick LaCrosse was a full redesign that repositioned the nameplate as Buick's flagship sedan. Built at the Fairfax Assembly plant in Kansas City, it ran through 2016 and received a meaningful mid-cycle refresh for 2014 that brought redesigned front and rear fascias, an eight-inch TFT instrument cluster, and new safety tech. A Sport Touring Edition arrived for 2016 with unique 18-inch black pocket wheels and a rear lip spoiler.
Engine options span a 2.4L four-cylinder, a 2.4L eAssist mild hybrid introduced as the base powertrain for 2012, a 3.0L V6, and a 3.6L V6 available in both flex-fuel and standard gas configurations. The CXS was the first North American car to feature GM's HiPer Strut front suspension, designed to reduce torque steer and sharpen handling. AWD was available on select trims, giving the platform broader appeal across driving conditions. Trim levels run from the base CX through CXL, CXS, Leather, Premium, and Sport Touring, with factory wheel sizes ranging from 17 to 20 inches depending on trim.
The 2014 LaCrosse rides on a well-sorted Epsilon II suspension from the factory. The CXS came equipped with GM's Real Time Damping system, which adjusts damping forces on the fly for a composed ride. Staying stock is a legitimate starting point, especially for owners focused on a clean, OEM-plus look with upgraded wheels and tires. The factory geometry supports 17- to 20-inch wheels with offsets in the +30 to +45 range, leaving room to step up to a sharper wheel-and-tire package without touching the suspension.
A set of lowering springs drops ride height and tightens the LaCrosse's stance without the complexity of a full coilover setup. The result is a more planted look, reduced wheel gap, and a slightly firmer, more connected feel through corners. Springs work with the factory struts and are a straightforward install for shops familiar with the Epsilon II platform. This is the entry point for owners who want a noticeable visual change and a crisper driving character while keeping daily comfort in the picture.
Adjustable coilovers give full control over ride height and, on quality units, damping as well. On the 2014 LaCrosse, coilovers let you dial in exactly how low the car sits and tune the suspension feel to match the build. The platform supports coilover fitment, and pairing them with updated alignment hardware gets the geometry right at the new ride height. This is the path for builders chasing a dialed, intentional stance: the right drop, the right offset, and a setup that looks and drives exactly as intended.
An aftermarket air intake opens up the induction path on the LaCrosse's four- and six-cylinder engines. On the 3.6L V6 in particular, a freer-breathing intake sharpens throttle response and adds a more pronounced induction note under acceleration. The 2.4L four-cylinder and eAssist hybrid variants also respond to intake upgrades, with improved airflow helping the engine breathe more efficiently across the rev range. It's one of the cleanest bolt-ons available and a natural first step for owners who want more engagement from the drivetrain.
A cat-back exhaust system replaces everything downstream of the catalytic converter, leaving the cat itself in place. On the 3.6L V6, the result is a deeper, more assertive exhaust note that suits the LaCrosse's premium character without going overboard. The 3.0L V6 responds similarly, with a cleaner, more refined tone. Four-cylinder owners get a sportier, more present note that adds character to an otherwise quiet powertrain. All configurations benefit from reduced backpressure and improved flow behind the catalytic converter.
Beyond intake and exhaust, the 2014 LaCrosse supports a range of supporting bolt-ons: upgraded spark plugs and coil packs for cleaner combustion, oil system components for better engine management, and valve train upgrades for the V6 variants. Brake upgrades are worth considering alongside performance work, particularly for owners who push the 3.6L harder, where upgraded rotors and pads compensate for the added demands. A supporting ECU tune gets the most out of a combined intake and exhaust setup, optimizing calibration for the full bolt-on combination.
The 2014 LaCrosse has clean, premium lines that respond well to targeted lighting and exterior upgrades, whether the goal is a sharper daily presence or a more personalized show-ready look.
Owners of the LaCrosse tend to treat lighting as an early upgrade, and the factory housings make that straightforward. Projector-style or LED headlight retrofits sharpen the light output and modernize the front-end appearance, a worthwhile upgrade on earlier models in the generation. Tail light upgrades with LED elements add a cleaner, more contemporary look at the rear. For interior ambiance, upgraded bulbs throughout the cabin bring a more refined feel. Sequential turn signals and DRL accent upgrades give the LaCrosse a more distinctive presence in traffic without altering the factory body lines.
On the exterior, paint protection film and clear bra coverage keep the LaCrosse's bodywork in shape, especially on the hood and front fascia where road debris does the most damage. Body accent pieces and pillar trim updates let owners personalize the look without major bodywork. Towing hitches are available for the platform, useful for light-duty hauling. Inside, custom-fit floor liners and cargo liners are the practical foundation of any interior build, protecting the LaCrosse's cabin from daily wear. Seat covers in materials that match the interior's premium character keep the upholstery protected. Interior lighting upgrades, including ambient and dome bulb swaps, round out the cabin without requiring significant modification.

It depends on your goal. Owners focused on appearance often start with wheels and tires, since a 20x8.5 +35 with 245/40R20 is a proven, clean upgrade that fits on stock suspension. Builders chasing stance start with lowering springs or coilovers to set the ride height first. Performance-focused owners often begin with an intake or exhaust. There's no single right order: start with the category that matters most to your build.
Yes. Get pre-approved before you start building your cart so you know your budget going in. Pre-approval is fast and lets you shop with confidence rather than guessing at what you can spend. Once you're approved, you can put together the full package, wheels and tires, suspension, performance parts, and accessories, and check out knowing the terms are already set.
