CREATE TABLE table_name_25 (laps INTEGER, grid VARCHAR(255), time_retired VARCHAR(255), constructor VARCHAR(255))
Where the time/retired is +1 lap, the constructor is BRM, and the grid is above 1, what's the highest laps recorded?
    
SQL: SELECT MAX(laps) FROM table_name_25 WHERE time_retired = "+1 lap" AND constructor = "brm" AND grid > 1
