The Scion tC, introduced by Toyota’s youth-oriented Scion brand in 2005, quickly became a favorite among entry-level tuners and racers. With its sporty coupe design, reliable 2.4-liter 2AZ-FE engine producing around 160 horsepower stock, and affordable price tag, the tC offered a solid platform for modifications. Discontinued in 2016 after the Scion brand’s absorption into Toyota, the tC remains a staple in grassroots racing scenes like autocross, time attack, and even amateur drift events. But to unlock its full potential on the track, enthusiasts turn to aftermarket racing parts that enhance power, handling, and durability. In this article, we’ll explore key upgrades that transform the street-friendly tC into a track beast.
Scion Tc Racing Parts: Engine
Starting with engine performance, the tC’s naturally aspirated inline-four craves forced induction for serious racing. Bolt-on turbo kits from brands like AEM or GReddy can push output to 250-300 horsepower with proper tuning, while superchargers from Jackson Racing offer a linear power delivery ideal for autocross. Supporting these are cold air intakes from K&N or Injen, which improve airflow and add 5-10 horsepower alone. Exhaust systems are crucial too—cat-back setups from Borla or Tanabe reduce backpressure, sharpen throttle response, and that signature growl. For reliability under boost, upgraded fuel systems like Walbro high-flow pumps and larger injectors are must-haves, often paired with an ECU tune via Cobb Accessport to optimize air-fuel ratios and prevent detonation.
Scion Tc Racing Parts: Handling Upgrades
Handling upgrades are equally vital, as the tC’s stock suspension leans more toward comfort than cornering prowess. Coilover kits from Tein or KW suspensions lower the ride height by 1-2 inches, adjustable damping for fine-tuning, and progressive springs that maintain daily drivability while gripping turns. Sway bars from Whiteline or Hotchkis minimize body roll, improving stability during high-speed slaloms. Complementing this, lightweight 17- or 18-inch wheels from Enkei or Rays, shod in sticky tires like Michelin Pilot Sport Cup 2 or Bridgestone Potenza RE-71R, provide the grip needed for sub-1:30 lap times at tracks like Laguna Seca. Bushings and control arms from Energy Suspension replace worn rubber, sharpening steering feel and reducing slop.
Scion Tc Racing Parts: Brake
Braking is another area where the tC shines with upgrades. The factory discs fade quickly under racing stress, so big brake kits from StopTech or Brembo—featuring 11.5-inch rotors and four-piston calipers—deliver superior stopping power and heat dissipation. Stainless steel brake lines and high-performance pads from Hawk or EBC round out the system, ensuring confidence in late braking zones.
Lightweight Parts
For the chassis, lightweight parts like carbon fiber hoods from Seibon or aluminum radiators from Mishimoto shed weight, improving power-to-weight ratios without sacrificing strength. Aerodynamic mods, such as front splitters, side skirts, and rear diffusers from TRD or custom fabricators, enhance downforce for stability at speeds over 100 mph. In racing series like SCCA’s Spec Miata alternatives or Formula Drift qualifiers, these mods help tCs compete against more exotic machinery. Go to this page auto racing performance parts
Investing in Scion tC racing parts isn’t just about speed—it’s about safety and enjoyment. Always consult professionals for installation, as improper tuning can lead to engine failure. With prices starting at $200 for basic intakes and scaling to $5,000 for full turbo setups, there’s a path for every budget. Whether you’re chasing podiums or just weekend thrills, the tC’s modding ecosystem proves it’s still a powerhouse in the used car world. Rev up your ride and hit the track— the competition won’t know what hit them.
