Even though all of McLaren’s 600LT Spider models coming to North America have already been purchased, the British carmaker is giving potential buyers the opportunity to land one of 12 cars featuring a unique Segestria Borealis design theme courtesy of MSO.

Each example carries an MSRP of $275,500, and features custom paint and interior detailing inspired by the venomous arachnid, Segestria Florentina

The cars, which have already gained the nickname ‘Spider Spider’, arrived in the U.S. this month and are now reaching select retailers who will be putting them up for sale.

The Segestria Borealis theme took the green fangs of the venomous spider and mirrored them in the twin Napier Green stripes that run from the nose of the car all the way to the top-exit exhausts at the rear. Meanwhile, the iridescent black body of the spider is represented by the Borealis Black MSO Defined paint, which has deep green, purple and claret undertones, depending on the angle of the light.

Other exterior features include the MSO Bespoke Napier Green brake calipers, 10-spoke gloss black wheels, Napier Green web motif on the rear wing and door mirrors, plus pinstripe detailing on the front fender, side skirt and rear diffuser vanes.

The MSO Clubsport Pack is also part of the spec, adding Super Lightweight Carbon Fiber Racing Seats, a Carbon Fiber interior upgrade, lightweight titanium wheel bolts and MSO Defined Gloss Visual Carbon Fiber front fender louvres.

Inside, the 600LT Spider Segestria Borealis comes with MSO Bespoke bright green stitching and webbing for the Alcantara trimmed racing seats, unique headrest embroidery, steering wheel stitching and 12 o’clock mark. It also has a Bowers and Wilkins 12-speaker audio system, McLaren Track Telemetry, rear view camera and parking sensors, lift system for the nose and a volumetric alarm upgrade.

As with any other McLaren 600LT, this one too is powered by a 3.8-liter twin turbo V8 unit, producing 592 HP (600 PS) and 457 lb-ft (627 Nm) of torque, allowing for a zero to 60 mph (96 km/h) acceleration time of just 2.8 seconds.

“The McLaren 600LT Spider Segestria Borealis by MSO is a singular example of the visionary, creative approach to the artistry of McLaren Special Operations. Like any 600LT, it is a purposeful, single-minded and menacing creation, but in this instance all the power and performance of this supercar is expressed in a unique and striking design scheme that fits with the desire of many McLaren owners to personalize their cars to make them truly their own,” said McLaren North America president, Anthony Joseph.
