A MILLIONAIRE thrill seeker died after crashing a Porsche at 200mph during a world record attempt in front of his wife.
Zef Eisenberg may have started braking too soon in the moments before he died while attempting to break a speed record in a Porsche 911 Turbo, an inquest has heard.

The 47-year-old was trying to prove he had created the world’s fastest Porsche when he was killed in a crash at Elvington Airfield, near York.
An inquest in Northallerton heard Mr Eisenberg was trying to break a number of land speed records in the “extensively modified” car in October 2020.
As he was finishing the last attempt of the day, his customised vehicle overturned at high speed and he suffered multiple traumatic injuries, dying at the scene.
The hearing was told Mr Eisenberg had asked for a braking parachute, designed to slow the car down, to be fitted to the vehicle as he created his own “bespoke design”.
A statement from race marshal Graham Sykes said the father-of-two had successfully used it throughout the day.
But on the final run of the afternoon, Mr Sykes said as the parachute deployed “the car began to lift as though air had got under it”.
The inquest heard this can cause the car to become “unstable” and lose control.
“Sadly I feel driver error caused this tragic accident,” Mr Sykes said.
He added Mr Eisenberg had been a “well known and much respected driver within British motorsports” and described his death as a “truly tragic incident”.
Malcolm Pittwood, appointed by Motorsport UK as the attempt coordinator on the day, said Mr Eisenberg was trying to break national speed records for a flying start and standing start.
He was also hoping to show he had created the world’s fastest Porsche for “bragging rights” on social media though that achievement would not be recognised by Motorsport UK.
He told the inquest: “Zef had in his mind that he was able to drive the world’s fastest Porsche motor car and he wished that information to be recorded.”
Mr Eisenberg had already survived Britain’s fastest motorcycle crash at the same airfield in 2016.
His motorbike failed to stop at the end of the runway, breaking bones in his legs and pelvis – which meant he had to learn to walk again.
The former teenage bodybuilder from north London had made his fortune with the Maximuscle fitness brand of protein powder.
He eventually sold it to pharma giant GlaxoSmithKline and moved to Guernsey.
An ultra-speed motorbike racer, in the past decade he had amassed more than 90 land speed records on two wheels and four.
After five years of intense work on a powerful bike, he set a new Guinness World record for the fastest turbine bike in the world at 234.01mph.
His enthusiasm for motor sport led to presenting the ITV show Speed Freaks, focusing on the design, build and engineering of extreme cars.
Following his death, Mr Eisenberg’s family described him as “a true genius with unique talents”.
