Looks cool, but why not just get solid motor mounts instead? If you set the engine dampners to be stiffer, the vibration is still gonna go into the chassis. So why not just eliminate the weak point and not have to worry about having dampners?

 

Because they look cool too!

 

Wow,very nice job. You can use some oven cleaner to get that anodized green off. It will need some polishing after though.
