MT gear ratios

[kudabee]

I have Finally finished the MT i bought on here replaced the diffs with evo3 and bought the center diff also what are the weak points and here is how i have it setup so far it has an alloy front brace alloy brake brace and an alloy gear mount and the alloy center diff holder with the new style Brakes.I just bought a RR competition plus edition and it is geared the same as the MT which i am confused about as I would think the gear ratios would be different due to the tire size so where do I go from here any help would be appreciated as i was running clones before i bought the mcds and am glad to have the real trucks NOW TY for any help as i just don't know where to go from here
