Stopping Power: Brembo Brakes
To match its incredible acceleration, the SRT8 needed equally impressive stopping power. This was provided by a high-performance Brembo braking system:
- Front Brakes: 14.2-inch (360mm) vented discs with four-piston Brembo calipers.
- Rear Brakes: 13.8-inch (350mm) vented discs with four-piston Brembo calipers.
These large, powerful brakes offered exceptional fade resistance and brought the heavy SUV to a halt with surprising urgency, instilling confidence in the driver.
Wheels and Tires
The SRT8’s aggressive stance was completed by its distinctive wheels and tires:
- Wheels: 20-inch forged aluminum wheels, lightweight yet incredibly strong.
- Tires: Goodyear F1 Supercar performance tires, sized 255/45R20 at the front and wider 285/40R20 at the rear. These tires were specifically chosen for their high grip levels, crucial for transmitting the HEMI’s power to the road and maximizing cornering performance.

- Dual Exhaust Tips: Large, polished dual exhaust tips exiting through the rear bumper were a clear indication of the power lurking beneath.
- SRT Badging: Discreet but prominent SRT and HEMI badges adorned the grille, fenders, and tailgate.
Performance-Oriented Interior
The cabin of the SRT8 blended sporty accents with the Grand Cherokee’s comfortable and practical layout:
- Sport Seats: Heavily bolstered sport seats, often with leather and suede inserts, provided excellent support during spirited driving.
- Carbon Fiber Trim: Genuine carbon fiber accents adorned the dashboard and door panels, replacing the standard wood grain.
- Unique Instrument Cluster: The gauge cluster featured a 180 mph speedometer and a prominent tachometer, along with "SRT" badging.
- Steering Wheel: A thicker, leather-wrapped steering wheel offered a better grip.
- Infotainment: While basic by modern standards, the SRT8 typically came with a Boston Acoustics premium sound system and optional navigation.
Despite its performance focus, the SRT8 retained the Grand Cherokee’s comfortable seating for five, ample cargo space, and a respectable level of luxury features, making it a surprisingly practical daily driver.
