Exterior highlights include new 20-inch diamond finish alloy wheels which are 20% lighter than forged alloy wheels along with 20-inch hollow carbon-fibre wheels available as an option. The Pista Spider also marks the debut of the Ferrari Dynamic Enhancer, a new lateral dynamics control which makes "on-the-limit driving more intuitive, controllable and predictable". In 2017 Ferrari won the drivers and constructors titles in the LM GTE Pro class of the FIA World Endurance Championship with the Ferrari 488 GTE number 51 of AF Corse, with Alessandro Pier Guidi and James Calado behind the wheel. As a tribute, a special edition of the 488 Pista was created called the 488 Pista Piloti which incorporates numerous technical and aerodynamic solutions incorporated from the racing versions of the Ferrari 488. The special edition has been developed by the Ferrari Tailor Made department, the division which is entrusted with all the customisations ordered by the customers, starting from the internal fabrics up to the colours and finishes. The exterior has a new livery with stripes in the colours of the Italian flag, reminiscent of the race winning 488 GTE and the word "PRO" indicating the racing class. The Italian flag colours are also present along the bottom of the doors which are also adorned with the personal race number of the client's preference. The launch version carries the number 51 used by the world championship drivers. Also part of this personalisation project is the matte black S-Duct and the natural carbon fibre "dovetail" suspended rear wing and vent surrounds. On the interior, Alcantara has been used throughout in order to give the driver the feel of a race car, with a special technique applied to upholster the sports seats in the same perforated material. The tricolour Italian flag is present in the seat upholstery, floor mats and paddle shifters. The colours available for the bodywork include Corsa red, Tour De France blue, Daytona black and Nurburgring silver. The 488 Pista Piloti is exclusively available for Ferrari drivers. The Ferrari J50 is a limited edition targa top based on the 488 Spider. It was designed by Ferrari styling centre under Flavio Manzoni and created by Maranello's Special Projects department. It was built to celebrate half a century of Ferrari's presence in Japan. The sharp, angular design of the car is an homage to the Ferrari sports cars of the 70's and 80's. It uses a two piece targa top made of carbon fiber which can be stowed behind the seats in place of the 488's folding hardtop.
