Founding partner of United Autosports Zak Brown has announced that he is putting his share of the business up for sale with immediate effect.

The team, which Brown co-owned with Richard Dean, contested a variety of Touring Car and GT Series in 2014 as well as taking care of Zak Brown’s extensive collection of active historic race cars.

The full statement from Zak is as follows:

Due to Zak Brown’s increasing business commitments around the world he has decided to put his share of United Autosports’ British Touring Car Championship (BTCC) team up for sale with immediate effect. The team ran two Toyota Avensis cars in the 2014 BTCC.

“I want United Autosports to be successful in the BTCC and, with my growing business commitments, I can’t dedicate myself to that as fully as I would like,” said Brown. “The BTCC is a high-profile and professional series and to run at the front takes time and I simply don’t have enough time to dedicate to the BTCC programme. United will continue to prepare and maintain my collection of historic cars and I very much look forward to competing with them in the future.”

United Autosports entered the BTCC in 2014 as well as contesting the Ginetta GT4 Supercup, British GT with the Audi R8 LMS ultra, GT Cup with a McLaren MP4-12C and Historic series and events in the UK and abroad. Since the formation of the team in 2009, United Autosports has had victories and podium finishes in GT races around the world and won the 2013 European Supercar Challenge, the Ginetta GT4 Supercup Teams Championship in 2014 and lead this year’s GT Cup standings with one round remaining.
