Lanzante, the UK racing team that helmed the legendary McLaren F1 GTR, announced back in June that it was planning a new mystery special-edition 'LM 25' series of McLaren models to celebrate the 25th anniversary of the McLaren F1 GTR winning the 24 Hours of Le Mans. The UK-based firm is also famous for its street-legal conversions of the McLaren P1 GTR. At the time, Lanzante didn't announce which McLaren model the LM 25 will be based on. We were hoping for a street-legal version of the McLaren Senna GTR, but Lanzante has confirmed the LM 25 will be based on seven different McLarens.

Limited to just seven examples as a homage to the seven F1 GTRs that raced at the 1995 24 Hours of Le Mans, each McLaren will be rebuilt to a special LM 25 specification replicating the F1 GTR.

Coupe and Spider versions of the McLaren 600LT and 765LT will be getting the LM2 5 treatment. A McLaren Senna and a Senna GTR will also be part of the collection.

A McLaren 765LT Spider version comes as a surprise since McLaren hasn't even revealed the production model yet - unless Lanzante has spoiled the surprise early. The seventh Lanzante LM 25 model is a complete mystery.

Each McLaren LM 25 conversion starts at £144,000 ($190,454) per car and takes around three months to complete. During this process, Lanzante changes the exterior color to Ueno Grey and grey tinted carbon fiber as a homage to the F1 GTR's Ueno Clinic finish and adds custom five-spoke carbon fiber wheels finished in grey with gold brake calipers finished with red McLaren lettering matching the original F1 GTR's Brembo brakes.

A retro 59 livery that pays tribute to the original number 59 race car and an LM 25 logo round off the exterior upgrades.

Inside, Lanzante's LM25 Mclarens are fitted with lightweight F1 GTR seats with red and blue racing harnesses that mimic the Le Mans car. These seats are 39.6 pounds lighter than the standard seats are feature the LM 25 logo in the headrest. Elsewhere, the steering wheel is wrapped in black Alcantara with white contrast stitching, complemented with carbon door sills, gold anodized interior switches and pedals, carbon floor mats, and a numbered plaque highlighting the car's exclusivity.

While there are no mechanical changes, each McLaren LM 25 will be fitted with gold ceramic heat shields and exhaust tips. The engine cover also features the LM 25 logo and the key is finished in the same Ueno Grey color as the exterior with an electroform LM25 logo.

Customers can either send their existing McLaren for the conversion or send a recently ordered one to Lanzante to receive the LM 25 treatment.
