Hi guys
16/19 topic.
What if we were to use newer front foams with like 50% foam tread left on the rear is this like the same effect as a front overdrive 16/19 thingy? im just asking out of curiousty. As today i learnt a lesson where my fronts were low and my rears where high (in terms of foam tread % left.) and the car kept spining or loosing control when giving the it power out of the corners. I was then told that because the rear wheels have more of a diameter the rear wheels are forced to push the front of the car.
Then i shoved on a brand new set and the car handled like it was on rails.

Let's be clear; when you install the 16/19 conversion, you overdrive the front pulley. i.e. the front wheels now spin faster than the rears.

When you then true the front tyres to ~4mm smaller than the rears, you restore the overall gearing to 1:1.

16 19 conversion
Bivens Thank you for answering my questions concerning tire wear with the conversion and all of the other information you have provided, I may give the conversion a try in the near future. I also agree with you about more tuning options for the car like 1/8 cars. But with these extra tuning options comes the ability to tune the car right out of the ball park, which I would hate to see a newbie do to this car. Even though the mtx3 has a very large suspension tuning sweet spot it can be put out of whack from poor adjustments, and the last thing a newbie needs is an ill handling car. My rambling point here is nothing new and directed to newbies spend your dough on tires and fuel the car is extremely competitive stock (and i don't mean prokit stock).

When do you guys set track width (199,200 etc) before or after setting camber and toe? I noticed if you set your toe after you set the width of the car it gets wider.

But....the stock setup is still great....you can always start there...make one change at a time until you fully understand the car...

Exactly the same concept as putting the conversion on the car without running smaller fronts.......Overdrive ratio well above 1.00....Gets really noticable on low-bite tracks and with OD ratios above 1.03.......

I'd just like to encourage everyone to keep an open mind...the best way to learn about the car is to try every possible adjustment (one-at-a-time) and know what happens with your car with those track conditions........for example....

One of the best tips I've tried to get rear traction on low-bite tracks is to cut-down the rear uprights (like the rubber-tire guys do in UK).....I think I learned about this from Cartman MANY pages ago in this thread.....(it works with foam tires also......anytime you need more rear bite mid-corner to off corner......)

Most people wouldn't try to tune a nice car like a MTX-3 with a hacksaw....but I have an open mind......and the rear uprights were a cheap replacement if it didn't work........

For all of you afraid of trying the 16/19 conversion....the cost is less than $10........give it a shot and see if YOU like it....that's what practice is for.......

ok i got the bearings. and when i screw down the clutch bell, i cant move it, so i dont think the shoes will be able to expand. where do i need to add shims to make it move a little bit?? if i can.

Make sure you installed it right, usually when you install it, there should be a lot of play , hence the need for shims.
