Seat Tuners – Motorsport

Advent Motorsport
Seat Leon Cupra

Following Championship winning success in the Mini Challenge the team decided to move forward and focused on the high profile nature of the British Touring Car Championship support packages.

The SEAT Cupra Championship offered an exciting and comprehensive package for teams and competitors alike. Advent Motorsport successfully ran cars in the 2007 Seat Supra Championship scoring a number of race wins and podium positions.

For 2008 the team moves forward to the new Seat Leon Cupra with DSG technology.
Advent Motorsport can offer race support to owners of the new generation of Leon or full race hire and preparation packages.
