well I bent my front spring when i stepped on that peice in the middle with the magnet and i need a replacement. Trouble is i cant find the part number from the rat shack and i cant find anywhere else to find them. Can someone help me? Also are the rare earth magnets worth it? i heard some people were having trouble with them. Im running tires that are the same highth as stock but are wider and probably heavier. Would the stronger magnet and two steering springs help? Right now its not having trouble moving the larger tires but halfway through a run the steering starts to slow down.
