What are the most popular modifications for a 2015 Honda Civic Si Sedan?
The 2015 Civic Si Sedan lends itself to a wide variety of modifications, catering to different budgets and performance goals. Popular choices include:
-
Engine Modifications: These range from simple bolt-ons like cold air intakes and cat-back exhaust systems to more involved upgrades like engine tuning (ECU flashing or piggyback systems), upgraded intercoolers (if applicable to specific tuning choices), and performance cams. These significantly increase horsepower and torque.
-
Suspension Upgrades: Upgrading the suspension is crucial for improving handling and responsiveness. Options include lowering springs, coilovers, and stiffer sway bars. This enhances cornering and reduces body roll.
-
Brake Upgrades: For improved stopping power, particularly after increasing horsepower, many Si owners opt for upgraded brake pads, rotors, and potentially even bigger brake calipers.
-
Wheels and Tires: A set of lightweight performance wheels paired with high-performance summer tires dramatically improve handling, acceleration, and overall driving experience.
-
Exterior and Interior Modifications: These are largely cosmetic but can significantly personalize the car. Options include aftermarket body kits, spoilers, lighting upgrades, and interior trim changes.

-
Suspension Issues: Aggressive lowering without proper consideration for suspension geometry can negatively affect handling and potentially damage components.
