 With the production run of the P1 GTR complete, and prompted by their efforts in converting track-only P1 GTRs to road-legal specification, Lanzante Motorsport commissioned McLaren Special Operations' Bespoke division to build a further total of 6 new P1 GTRs for them to develop into road-legal P1 LM variants.Of this production run, five P1 LMs were sold and the sixth, the prototype P1 LM codenamed 'XP1 LM', was retained and is now being used for development and testing of future models.In order to convert the cars into the P1 LM specification, Lanzante Motorsport made changes to the drivetrain hardware (to increase power output), employed a modified rear wing and larger front splitter along with dive planes (to improve downforce), removed the air-jack system and installed Inconel catalytic converter pipes and exhaust headers, lightweight fabricated charge coolers, Lexan windows, lighter seats (similar to those used in the F1 GTR) and a titanium exhaust system, bolts and fixings (to save weight).
