Nashville’s vibrant car culture and growing calendar of track events make it an ideal playground for those who want to push serious horsepower to the limit. The Dodge Challenger Redeye, with its supercharged 6.2‑liter HEMI V8, is already a street‑ready monster. But transforming it into a dedicated track‑day weapon requires careful selection of upgrades that complement the car’s strengths and address its weaknesses. Whether you plan to run laps at Nashville Superspeedway or participate in autocross events at Music City Raceway, this guide will walk you through the essential steps to build a Challenger Redeye that performs reliably and safely on the track.

Understanding the Challenger Redeye

The Challenger Redeye delivers a staggering 797 horsepower and 707 lb‑ft of torque from the factory. Its supercharged 6.2‑liter HEMI V8 is paired with an eight‑speed automatic transmission (TorqueFlite 8HP95) and a limited‑slip differential. While the car is undeniably fast in a straight line, its standard suspension, braking system, and tire package are optimized for street comfort rather than sustained track use. Heat management also becomes a critical factor: the Redeye’s engine and transmission can generate enormous thermal loads during repeated high‑speed laps. Acknowledging these baseline characteristics helps you prioritize upgrades that will yield the biggest performance gains on a road course or drag strip.

Essential Upgrades for Track Performance

Building a track‑ready Challenger Redeye means moving past simple bolt‑ons and targeting system‑wide improvements. Below are the key areas that demand attention, along with specific recommendations for Nashville’s varied track environments.

Performance Tires

Stock all‑season tires cannot handle the lateral loads and heat cycles of track driving. Invest in a set of dedicated track‑day tires, such as the Michelin Pilot Sport Cup 2 or Nitto NT01. These provide superior grip, predictable breakaway characteristics, and consistent performance lap after lap. For drag strip days at Music City Raceway, a set of drag radials (like the Mickey Thompson ET Street R) can improve straight‑line traction. Always run a separate set of wheels for track use to preserve your street tires and avoid frequent remounting.

Suspension Upgrade

The Redeye’s factory suspension is tuned for comfort and straight‑line stability. To improve cornering grip and reduce body roll, install a performance coil‑over system such as the KW Variant 3 or Bilstein B16. Adjustable dampers allow you to dial in rebound and compression for different track configurations. Additionally, upgrading the sway bars (front and rear) with Eibach or Hotchkis units will sharpen turn‑in response. If your track day includes road courses with heavy braking zones, consider adding spherical bearings in the control arms for more precise alignment.

Brake System

Stopping a 4,500‑lb Challenger from triple‑digit speeds requires a brake system that can tolerate intense heat without fade. Start with high‑performance brake pads like Hawk DTC‑70 or Ferodo DS3000. Replace the factory rotors with two‑piece floating units (e.g., Brembo Racing** or **StopTech**) to reduce unsprung weight and improve heat dissipation. Brake fluid should be upgraded to a high‑temperature DOT 4 or DOT 5.1 fluid such as Motul RBF 600. For serious track regulars, a full BBK (big brake kit) with 6‑piston calipers and larger rotors is a worthwhile investment.

Exhaust and Intake Systems

Improving airflow helps the supercharged HEMI breathe more efficiently. A full cat‑back exhaust system from Borla, MagnaFlow, or Corsa reduces backpressure and sheds weight compared to the factory system. Pair it with a high‑flow intake (like the Roto‑Fab** or **AFE Power** intake) to give the supercharger easier access to cool air. Note that some track day organizations require a noise limit (typically 95–105 dB) – check the noise policy at your venue before selecting an exhaust.

Engine Tuning

While the Redeye’s engine control unit is already aggressive from the factory, a professional tune can optimize parameters specifically for track conditions. Work with a trusted tuner who understands the limitations of the stock fuel system and cooling capacity. A custom tune might reduce the cooling fan engagement temperatures, adjust spark timing for higher octane fuel, and sharpen throttle response. For sustained track use, consider upgrading the heat exchanger for the supercharger intercooler system (e.g., AFE Power** or **Mishimoto** units) to keep intake air temperatures in check.

Cooling Upgrades

Heat is the enemy of a forced‑induction engine during repeated laps. In addition to a larger intercooler heat exchanger, upgrade the engine oil cooler and add an auxiliary transmission cooler. Many track‑oriented Redeye owners also install a larger radiator (like the Mishimoto** or **CSF** units) and an electric water pump to maintain flow at idle. Keep an eye on oil and coolant temperatures with a dedicated gauge package – consider a AEM** or **AutoMeter** digital display that integrates with the car’s OBD‑II port.

Weight Reduction

Every pound saved improves acceleration, braking, and tire life. Start by removing the rear seats, floor mats, and spare tire. Swap the heavy factory seats for fixed‑back racing buckets (e.g., Recaro Pro Racer** or **Sparco Evo**) mounted on lightweight brackets. Replace the battery with a lightweight lithium‑ion unit like the Antigravity Batteries** or **Braille** – and relocate it to the trunk for better weight distribution. Carbon fiber body panels (hood, trunk lid, fenders) are expensive but offer substantial savings at the track.

Safety Equipment

Nashville area tracks often require a minimum of a driver harness and helmet for high‑speed events. A six‑point harness from Schroth** or **G‑Force** keeps you firmly planted during hard cornering. Install a bolt‑in roll bar (e.g., from Autopower** or **Watson Racing**) to provide structural rigidity and a mounting point for the harness. A fire extinguisher with a quick‑release bracket and a first aid kit are mandatory at many tracks. Upgrade to a track‑spec helmet meeting SA2020+ ratings – both open‑face and closed‑face options are available.

Preparing for Nashville Track Days

Nashville’s track season runs from March through November, with peak summer temperatures often exceeding 90°F. Before any event, perform a thorough inspection that includes:

  • Tire tread depth and pressure – target cold pressures around 32–35 psi for road courses, lower for drag racing.
  • Brake pad thickness – you need at least 50% pad life for a full day of sessions.
  • Fluid levels – engine oil (consider 5W‑50 for track use), brake fluid, coolant, and transmission fluid.
  • Wheel torque – verify all lug nuts are tightened to the vehicle’s specification.

Familiarize yourself with the specific track layout. Nashville Superspeedway offers a 1.33‑mile oval and an infield road course; Music City Raceway is a 1/8‑mile drag strip. Find out the run group format (novice vs. advanced) and whether you need to pass a tech inspection. Organizations like NASA Tennessee and Chin Track Days frequently host events in the area. Register early because spots fill quickly, especially for popular dates in spring and fall.

Safety Tips

No matter how well your Redeye is prepared, driver safety remains paramount. Follow these guidelines:

  • Always wear a helmet that meets SA2020 or FIA 8859 specifications – many tracks require a full face helmet if you have a convertible or open‑window car.
  • Use a nomex suit and gloves for events with multiple cars on track – fire protection adds a critical layer of safety.
  • Install a fire suppression system if you plan to run in advanced solo groups – a hand‑held extinguisher is the minimum.
  • Carry a comprehensive first aid kit and know the location of the nearest trauma center (e.g., Vanderbilt University Medical Center in Nashville).
  • Never exceed your own skill level – consider taking an advanced driving school at the Nashville Speedway or with the SCCA to improve car control.
  • Keep a logbook of your modifications and maintenance – this helps you stay organized and spot potential issues before they become dangerous.
