Springs
 

How do u install springs? i tried and messed it up

Unscrew the cover to the steering things that hold the wheels. Put the springs on the pole part (the top one) and close it back up. How'd you mess up?

the springs are magnetic and when i put the cover thingy on it just lifts the springs out of place and messes up the arm thingy with the magnets. Is it worth doing this mod?

Do you mean steering, or suspension springs? If you mean steering, put them on, then tack them down with a very little bit of Superglue. If suspension springs, I have never had a prob w/ this.
