Time goes by

Whilst kids, family and work keep me off writing news, my old friend Mexx put another 2500hours work in his Ghia Racer. The hell knows who gave him the energy to move forward on the project this fast. You may say other racers are built in one year. Thats right but they are built from shopped parts. This one is built from 100% Mexx parts. Still the maxim is “how to modify dam everything…” which was overruled the last years by “how to fabricate dam everything…”

Pictorial overview ( take your time, about 400pics)

First rollout this summer? Hopefully there is a lot of work left.

Weight is the enemy

A quote from the most famous industrial designer Raymond Loewy . No one should forget when building a racecar. Lightened motorbike brakes for the tubechassis racer.
