So it was mentioned that one of the new things will be "harder" plastics. Does this mean stiffer (more brittle), or was this meant to mean stronger. After the upgrade to the V2 suspension parts, I am not seei g a need for a return to harder plastics. I broke several V1 C-Hubs, spindles and arms on my Ghost and D05. After I changed all the parts over on my Ghost, and got the D06, I have a bunch of spares I have yet to use. My car handles great on carpet, is very durable, and I thought you would want more flex for low traction asphalt. So why the need for "harder" plastics?
