An exceptional and extensively developed R35 GT-R with over £48,000 of documented servicing, maintenance and upgrades, together with a level of history and documentation which is unheard of. This is not simply a tuned GT-R with a list of unverified upgrades; the car is accompanied by its original Nissan GT-R maintenance book, extensive invoices, Litchfield dyno printout and a substantial paper trail documenting its development and maintenance throughout its life. Litchfield Stage 4.25, historically dyno proven at 689.7 BHP and 636 lb-ft, with the car subsequently receiving further Litchfield upgrades including Race Plus intercooler and pipework, speed-density conversion, Nuke dump valves and Version 10 software. Further specification includes Litchfield gearbox software, 102mm exhaust system, upgraded bellhousing, billet engine sump, billet gearbox sump, uprated PAS cooler and documented gearbox valve-body rebuild. Stopping performance is equally impressive with Alcon 400mm front brakes, Alcon rear discs, Ferodo DS2500 pads and Goodridge braided lines, sitting behind striking Candy Red wheels with Michelin Pilot Sport 4S tyres. The exterior features extensive genuine carbon-fibre detailing including carbon bonnet, rear wing, front splitter, grille detailing and additional carbon trim, complemented by the desirable Recaro interior, Bose audio, Apple CarPlay/Android Auto and red-accented sports seats. The history is outstanding. Initially maintained by Nissan main dealers and subsequently cared for extensively by Litchfield, with mileage records progressing consistently throughout the car's life. The accompanying invoices document in excess of £48,000 spent on servicing, maintenance, upgrades and specialist work. A truly special R35 for the enthusiast who wants something far beyond a standard GT-R: enormous performance, carefully selected upgrades, exceptional provenance and a specification that would cost a small fortune to replicate. Undoubtedly the very best documented GT-R currently available.
