Ok, I got my Tomy springs...they're terrible! I tried them in my bit- too much tension. I cut them to about 1/4 the original length and the car still ramdomly turn. They are the exact same length, I've spent over 2 hours trying to tweak them. Don't bother with them, I can't believe some people say that they help steering. The only thing they do is add more friction and prevent steering.
