3.31 to 3.73 worth it?

Yes it,ll help you off the line more.Do you drive on the highway?3.73,s won,t be all that much difference.Have you thought about a second set of rear tires for the track?Smaller ones will make a difference,just like a taller one will.You could always get a second center section also with a different gear for the track.Just sayin..:burnout:
