XRAY - Model racing cars

I'm bored at work so i've been thinking about diferent things i would like for my Xray.

Has anyone at Xray thought about making plastic driveshafts like Schumacher? I drove a mission before i got an Xray and i always thought that the plastic driveshafts were a really good idea. They are lighter, don't bend (of course they do break instead) and cheaper than metal driveshafts. This might only work for the tourers ie not the XB8.
The problem i can see with them for the Xray is the designing/molding costs. Well what do you think?

Bigger bottles of Shock oil, i always wonder why they are so small.

Seperate packs of balljoints for the bottom of the shocks. I hate having to buy the full plastic parts tree to just use the balljoints. (i think this has been brought up before)

I would be happy to know what other people would like aswell, you never know Xray might make them

Hi
I have a friend that managed to shear one of the sping steel drive shafts with a modified and a spool so it would make mince meat out of a plastic one especialy with the no motor limit in the uk
