The Acura RSX, produced from 2002 to 2006, remains a cornerstone of the sport compact tuning world. Built on Honda’s renowned K-series engine platform, this front-wheel-drive coupe blended everyday usability with exhilarating performance. Enthusiasts quickly embraced it for grassroots racing, autocross, and track days, transforming the RSX into a drift king and drag strip contender. Its lightweight chassis, responsive handling, and modifiable nature make it ideal for aftermarket upgrades. But what truly elevates the RSX is a curated selection of racing parts that unlock hidden potential. In this article, we’ll explore key components to supercharge your RSX, focusing on reliability, power gains, and track-ready grip.
Starting with the heart of the beast: engine modifications. The stock 2.0L K20A3 engine in the base RSX delivers 160 horsepower, but racing demands more. Cold air intakes from brands like AEM or Injen replace the restrictive factory airbox, improving airflow and adding 5-10 horsepower instantly. Pair this with a cat-back exhaust system from Borla or Skunk2, which reduces backpressure and enhances throttle response while delivering that signature growl. For serious power, turbocharger kits from Jackson Racing or Comptech can push output beyond 300 horsepower. These setups include intercoolers, blow-off valves, and ECU tunes via Hondata systems, ensuring safe boosts without grenading the engine. Remember, high-compression pistons and reinforced rods from Wiseco are must-haves for sustained track abuse.
Suspension upgrades are crucial for taming the RSX’s eager chassis. The car’s MacPherson strut front and multi-link rear setup handles well stock, but coilover kits from Tein or KW elevate it to pro levels. Adjustable damping and ride height allow precise cornering, reducing body roll during aggressive turns. Complement these with sway bars from Eibach (front 22mm, rear 19mm) to sharpen turn-in and minimize understeer—a common RSX trait. Bushings from Energy Suspension replace worn rubber, restoring factory-fresh precision. For ultimate control, limited-slip differentials (LSDs) from Quaife or MFactory distribute power evenly to both wheels, preventing wheelspin on corner exits and enabling smoother drifts.
Braking is non-negotiable for racing safety. The RSX’s stock discs fade under hard use, so upgrade to big brake kits from StopTech or Brembo. These feature larger rotors (up to 11.8 inches front) and multi-piston calipers, paired with Hawk HPS or EBC Yellowstuff pads for superior bite and heat resistance. Stainless steel brake lines from Goodridge eliminate sponginess, ensuring pedal feel remains firm lap after lap.
Wheels and tires tie it all together. Lightweight forged alloys from Enkei or Rays (17×7.5-inch) shed unsprung weight, improving acceleration and handling. Wrap them in sticky rubber like Michelin Pilot Sport Cup 2 or Bridgestone Potenza RE-71R for maximum grip—essential for autocross or time attack.
Beyond the mechanicals, aerodynamic aids like APR front lips and GT-style rear wings from Seibon reduce lift at speed, while Recaro racing seats and six-point harnesses from Schroth keep you planted. These parts, sourced from tuners like Commonwealth or online hubs like RSXType-R.com, form a cohesive build.
Investing in Acura RSX racing parts isn’t just about speed; it’s joining a vibrant community that celebrates ingenuity. With proper installation and maintenance, your RSX can dominate local tracks for years. Whether you’re chasing sub-7-second 0-60 times or podium finishes, these upgrades turn a daily driver into a racing legend. Budget wisely—start with bolt-ons and scale up—but always prioritize safety. The RSX’s legacy endures, fueled by passionate modifiers pushing boundaries one part at a time.
