This 2005 Lotus Elise was purchased new by the seller and converted to a NASA ST1/TT1/TTU track car by BOE Fabrication in Overland Park, Kansas. The modifications included front and rear carbon fiber clamshells, custom aero components, a 6-point roll cage, Penske suspension, AP Racing brakes, and more. Power comes from a supercharged 1.8L 2ZZ-GE four that can run several tuning configurations and is paired with a Quaife BWR 300M sequential manual transmission. Records from 2005-2007 are included in the sale, and a detailed build list is available here. The car has reportedly claimed a number of track records during its career and is now offered with spares including an extra Quaife gearbox and a Kansas bill of sale.

The body is made from dry-laid carbon fiber and styled around a circa-2010 Exige front clip and a 6″ widebody rear clamshell. The seller states that the front shell weighs about 11 pounds and the rear shell 15 pounds. An 8″ carbon front splitter is present along with Reverie canards, custom aluminum side skirts, and a BOE diffuser. A custom Crawford swan neck wing is mounted to the rear frame using 7×7 carbon fiber uprights with honeycomb cores.

The car rides on a set of 15×8″ Enkei wheels with 245-width tires on the front and 15×10″ 949 Racing wheels with 275-width tires in the rear. The ride height is set to approximately 70mm using custom-valved Penske shock absorbers, 900 lb/in front springs, and 1,100 lb/in rear springs.

A pair of AP Racing 5000 Pro calipers can be seen behind the front wheels, while rear braking is from AP Racing Lotus front calipers. The rotors are two-piece full floating units from BOE and the brakes are controlled by a BOE manual brake bias cage with a Tilton bias bar.

The interior features a 60/40 split aluminum firewall along with a VSA 6-point roll cage, a pair of Tillet carbon seats, Schroth harnesses, and more. A remote brake bias adjuster is present on the dash and the included data logging system is comprised of an AiM Evo 4+, AiM formula wheel, AiM Smarty camera, and BOE Fastworks software.

The supercharged 1.8L 2ZZ-GE four features 10.5:1 compression and is equipped with Arias pistons and a BOE dry sump oiling system. A CNC-ported JCR cylinder head is fitted with a Ferrea valvetrain with dual springs and solid rockers as well as stage 3 cams. Other additions include a DMC stainless exhaust header and BOE surge tank. Two Lotus T4 ECUs are included, with each tuned for one of the following power configurations:

  • Current setup: Whipple 2300 blower, pulley, tune, and belt; 100 octane fuel; 430 WHP
  • Alternate setup: TVS 1320 blower, pulley, tune, and belt; 100 octane fuel; 330 WHP

Two 6-speed Quaife BWR 300M sequential manual transmissions are included in the sale, each with a specific upper gearset to tune top speed to either 140mph or 165 mph.

The seller notes that the car has not been raced since 2016, but was used at a few track days in 2017 and 2018. The motor, transmission, muffler packing, and brakes have one track weekend since being updated at the beginning of 2018. An on-track video can be viewed above.
