This Brunton Stalker XL Is A Street-Legal LS-Powered Go Kart
The 2018 Brunton Stalker XL isn’t just another Lotus 7 replica. This is an all-out Brunton Level Six build that blends lightweight British sports car styling with American grunt. Built by Brunton Auto in Clearwater, Florida, this Stalker XL was ordered as a complete turn key car, not a half finished DIY kit. The result is a raw and focused road machine with just the right mix of heritage and horsepower.
Classic open top design meets Chevrolet Performance’s 6.2-liter LS3 crate engine, backed by a Tremec Magnum 6-speed and a full set of track-proven upgrades. This Stalker isn’t a tribute, it’s a reimagined version of what a Lotus 7 might have become if it had grown up in Detroit.
LS-Powered Minimalism with Real Performance Hardware
Under the vented hood sits the 430-horsepower LS3, topped with a flipped intake manifold and rear-entry cold air intake system. Exhaust is handled by a set of long-tube headers that feed into a side-exit exhaust. A custom aluminum dual-pass radiator with an electric fan keeps temps in check, even under hard use. Power flows through a McLeod twin-disc clutch to a Cadillac CTS-V rear differential with limited slip and 3.73 gears.
The chassis features four-wheel independent suspension with Penske Racing double adjustable coilovers. Braking is taken seriously with Wilwood power assisted disc brakes with 6-piston calipers up front and 4-piston units in the rear give the Stalker serious stopping power. Black XXR 531 wheels, 18×11 rear and 18×9.5 front, are wrapped in Toyo Proxes R888R tires, 315/30ZR18 in the rear and 255/35ZR18 up front. Rack-and-pinion steering is handled by a Coleman unit with electric assist, keeping feedback tight without sacrificing comfort.
Driver-Focused Cockpit with Track-Ready Details
Inside, the no-frills cockpit is built for business. Scat Procar black racing seats hold driver and passenger securely, while a three-spoke Grant steering wheel sets the tone. The dashboard is clean and functional, with Speedhut gauges for voltage, fuel, coolant temp, and oil pressure, plus an 8,000-rpm tach with programmable shift light and a centered 160-mph speedometer. The digital odometer reads just 3,500 miles, most of which were put on by the original owner.
This is a purpose built machine for people who want real performance and minimal distractions. At just over 3,500 miles, it’s barely broken in. The Brunton Stalker XL stays true to the spirit of the original Lotus 7. Stripped down, brutally fast, and focused on driving.
