Dodge Challenger Hellcat Redeye Runs a 9.46 at Las Vegas Motor Speedway

A stock-appearing Dodge Challenger SRT Hellcat Redeye just put up a 9.46-second quarter-mile pass at nearly 148 mph during a Test and Tune night at The Strip at Las Vegas Motor Speedway — and it did it against a Ford Mustang Shelby GT500, one of the Hellcat's most credible street rivals. autoevolution has the full rundown, including the Redeye's red-light start — which means it ran that 9.4 on sheer horsepower alone, not a perfect reaction time.

The numbers behind that pass are worth sitting with for a second. The Redeye's 6.2-liter supercharged HEMI puts out 797 horsepower from the factory. Getting to the other end of a quarter-mile at 148 mph is the exciting part. Scrubbing that speed back down to zero is the part the brakes have to deal with — repeatedly, on a busy test-and-tune night, with the car still hot from the previous run. The factory six-piston front setup is genuinely capable hardware, but two-piece rotors exist precisely for situations like this: the floating aluminum hat decouples thermal expansion between the hat and the ring, so the rotor stays true under heat cycles that would warp a solid unit.

Paragon 2-Piece Front Rotors for the 2015-2020 Hellcat

The Paragon Upgraded Front Pair Performance 2-Piece Rotors for the 2015-2020 Dodge Challenger and Charger SRT Hellcat measure 390mm x 34mm — that's about 15.4 inches across and 34mm thick, running directly with the factory six-piston Brembo calipers. The ring is a separate floating piece from the aluminum hat, which lets each component expand and contract independently under heat. The result is a rotor that stays flat through repeated high-load stops, resists cracking at the vane roots, and weighs less than an equivalent solid disc.

At $1,050 for the front pair, this is an upgrade that fits the scale of the Redeye's performance. If you're running the strip, tracking the car, or just want the rotors to match the seriousness of 797 horsepower, a two-piece setup is the right move over a direct OE replacement.
