what you need to do the conversion is get an extra 16T pulley, put the rear 19T to the front and affix the extra 16T to the rear. and at last you need a shorter side belt. kawahara carries the shorter long belt for this conversion and there is someone on this forum selling the shorter long belt.

i tried the alloy pulley and i dont like them as they wear too fast. stick with the plastic pulleys.

with the 16/19 conversion, you may use smaller tire in the front which is the purpose of the 16/19 pulley conversion.

why you need to shaved your steering linkage and deburred the diff case?
So with this conversion, do you HAVE to true the front tires down to get the full benefit?

and dont forget that when running a smaller tire on the front you will have to adjust your droop accordingly

As I understand this, because of the way the MTx3 wears the rears so much more than the fronts, the handling will go away, at least it did on my car. So "they" came up with this fix, so to speak. When running the 16/19 change, you run the fronts 4mm smaller than the rears, and at the end of a 30-45 min main the car still handles as well as it does at the start of the race. Because the tires are almost even after 30 min, at my track.

That is my understanding too red5
but I have not yet tried this belt and pulley configuration
my question though to those that have experience with this
gearing/belt configurationi s this If you begin the 30 minute main
with front tires 4 mm smaller, then you say the tires wear evenly that means that when you finish the main the front tires will still be 4mm smaller than the rear tires right(because this would have to be the case for consistent handling. Is my thinking correct here?

I usually start with a 3.5 mm split and after 30 minutes still have a 3 mm split.

The car handles much more consistent during the entire main.

We have a guy at the track who runs the belt conversion w/o any split, he says he likes the overdrive.

He's fast, but I think this is putting tons of strain on the drive train.

I have never heard of this problem. I have run My mtx3 in numerous 30 min mains. I have never noticed a significant difference in the way the car handle in the first 5 min to the last 5 min. I look at my lap times. they don't vary much. if i was running a 11:9's at first 5 min. I still can run 11:9's in last 5 min.

who makes this conversion piece?

I run softer rear tires with harder springs and found that the rears would be smaller than the fronts at the end. That's why I changed to it.

You may be compensating for the difference thru the race without noticing the handling difference. If not leave it off, you don't need the change.

I like running the conversion.
