I'm willing to bet that now with the rubber tire compounds available for the 104 that there may be no rubber still available for the 103 that will keep it faster than or maybe even as fast as the 104.
I'm sure the Rides we've got are not gonna do it.
I haven't tried any Pit Shimizus in 103 sizes tho.
Don't even know if the compounds are the same for 103 and 104.
