I just have a quick question hoping someone here might have an answer . I'm ordering the yeah racing titanium screw set to replace the stock screws in my TT02. I think these screws are all metric sizes but I have no idea about what hex driver size I will need for the installation. I checked the yeah racing website but it doesn't say anything about that. So my question is what size do I need? I have hex screw drivers in SAE sizes but not metric at the moment Thanks in advance.
