All the works were carried by an official Mercedes dealer appointed for those very special conversions. Otherwise I would have never considered modifying a single bolt.
Afterwards that car drove like in a dream and was trouble-free
I can't remember precisely all the techs details but it was something like 350 BHP, 0-100MPH in 14 sec, speed was 155mph (because the original speed restrictor was kept)
Yes the suspensions was upgraded... as well as the modifications on the engine, radiator, gear-box, steering column, chassis, exhaust, brakes and tires, the all works.
I knew that car's series well, to me they were originally perfect and offering plenty joyful time, but with this conversion it was like driving in paradise. I adored it
