MY new mod idea
 

i dont know if this will work. ok has anyone tried to put two sterring springs on there car would it give me more powerful sterring???

i think it would make it stiffer- whichwould mean sluggish when turning, snaps back quicker when returning to center.

this could be useful
 

Good idea.
While it may not be practical for every bit I think it would be very useful on a drag bit.It could help to keep the wheels pointed straight.
