David Haye will be conceding 37lbs to Dereck Chisora when the British rivals meet at Upton Park on Saturday night.
Haye scaled 210lbs at a feisty weigh-in at the Odeon Cinema, Leicester Square, the lightest he has been for any of his six heavyweight fights.
Chisora, the underdog, will enter the ring with a two-and-a-half stone advantage after totaling 247lbs.
Both fighters arrived with large entourages that crept within five metres of each other as Haye and Chisora weighed in, cheered on by their supporters in a packed room.
It was the fourth time Haye and Chisora have met since their infamous brawl in Munich five months ago, an incident that created the demand for Saturday's showdown.
As usual a steel fence was in place to separate them and they weighed in either side of the barrier.
When they came face to face through the mesh, Chisora and his trainer Don Charles taunted Haye.
"We drive the same cars and we're going to have the same records," Chisora said.
"I've had three losses and after the fight he'll have had three losses. We'll be even. I'm coming for you.
"I'm feeling good, I'm excited and I can't wait. It's going to be a great fight, the fans will love it."
Haye highlighted Chisora's lengthy criminal record and conduct within boxing as the reason for his hatred of the 28-year-old and he branded his opponents' supporters "idiots".
"Chisora's not a nice guy, the fact he bites people in the ring, spits water in peoples' faces, slaps people at weigh-ins, kisses people at weigh-ins. What's to like?" he said.
"I don't know how anyone in their right man could support Dereck Chisora, a convicted woman beater.
"Who would support someone like that? Someone who says and does the things he does? What is there to support?
"What type of sane human being supports someone like that? Maybe another idiot would, someone like himself.
"There were a handful of idiots here who supported him, they were probably his mates."
Haye insisted Puerto Rican referee Luis Pabon is equipped to deal with any erratic behaviour from Chisora.
"We've got a good referee who won't stand for any foolishness and I'm confident he will handle anything," he said.
Charles also faced-off with Haye at the fence and later explained the anger he directed at the 31-year-old.
"I try my best in all the fights Dereck has had in the past to not get emotionally involved," he said.
"But I can't stand David Haye. The arrogance he shows is beyond belief. He's delusional and lives in a dream world.
"He's a guy who plays a lot of Playstation games and he gets caught up in that mindset, he thinks it's all a game, but this is real."
