There are definative pros and cons here, the cons easily outweight the pros though, biggest problem is from what i can see the welds on the back are ahead of the axle and when you land all pressure will be on thoughs weld and will snap it, from what i would imagine to be easily snaped at that.
all i can say is when i first saw this i just started laughing my ass of hahaha
