I'm not too much into the 1/4 races due to the face I don't have a track too close here and I don't want to break parts all the time, but If I do run, it's usually from a 40-60 mph roll. Would 3.55's be better than the 3.07? It just seems when I accerate..my car pulls real hard but seems to take forever to shift into the next gear>....is this a good idea or bad idea?
