I ordered a massive load of titanium bolts, washers, banjo bolts and nuts. A small batch of more uncommon stuff at a local dutch company called Titanium Race Parts. The other large batch directly at a factory that specializes in Titanium, thus saving a bit on costs.  This should be everything I need for the whole bike. Every bolt will be titanium. Saving around 3.1kg of weight. Damn this stuff is beautiful. Costs however, 2600 euro’s total are less amazing haha….
