Gibson Technology

In 1987, Zytek bought the British Alan Smith Racing outfit in order to expand its motorsports involvement.

In 2002, Zytek bought some of the remains of the defunct Reynard Motorsport from International Racing Management (IRM).

These assets included the rights to the Reynard 02S Le Mans Prototype, of which only one had been completed since the company's demise.

Due to changes in the prototype regulations in 2006, Zytek upgraded one of their existing 04S chassis while building a third all-new car, named the 06S.

Two of the many LMP2 cars powered by Gibson engines finished on the overall podium, and one led the race overall for some time until a recovering factory Porsche reclaimed the lead.

In February 2019, ByKolles Racing announced that they would be switching to the Gibson GL458, dropping the Nissan Nismo VRX30A 3.0 litre twin-turbo V6, for their CLM P1/01.
