The gang, seen wearing the Muslim women’s clothing in the days leading up to the killings, were convicted at the Old Bailey yesterday.
They were caught when they set fire to a car with their clothes and burkas inside — but they survived the blaze, giving police DNA evidence.
Zain Mirza, 21, ordered the hit to avenge his brother — stabbed to death three years earlier.
Along with three others, he burst into a house and opened fire in Ilford, East London, in 2022.
Rappers Saydi Abu Sheikh, 23, and Zakariya Mohamed, 31, were killed and two others injured.
Prosecutor John Price, KC, said: “The four killers had each discarded the outer layers of upper and lower clothing they had been wearing when in Henley Road.
“It was all placed in the back of the SUV. Using an accelerant, which was probably petrol-given the fire began with an explosion and the nature of the aroma detected, they then torched the vehicle.
“Clearly their intention had been to destroy, not only the vehicle, but also the outer layers of clothing they were each wearing when committing murder.”
The gang, found guilty of two murders and two attempted murders, will be sentenced next month.
