Here in the SF bay area, we have a couple of guys switch from m04 to m03. I think the 17t pinion limit for the m04 is just right. When we race with the m04, I think they are still a little faster towards the straight than the m03. Just the m03 will eat the rwd in the corners. I guess with the larger tires, they had to limit the m04 gearing to a 17t. I think the m03 is more fun anyways.What is the ratio of fwd and rwd minis racing in the tcs finals[previous]?
