In 1988 goes on sale the double album Timbiriche VIII & IX. The reason for producing a double album was that the producers did not decide to choose the repertoire of songs that would include in the new album. At that time, the double discs were a novelty in Latin America and few artists were encouraged to produce them. The album (which was also released for sale separately) included the hit singles "Tú y yo somos uno mismo", "Ámame hasta con los dientes", "Acelerar", "Yo no se si es amor", "Me estoy volviendo loca", "Junto a tí", "Máscaras", "Pasos" and "Tú me vuelves loco". This period is considered as the zenith in the trajectory of the group and gives another step in its evolution, positioning itself as a young adult band.
