You need to drill two countersunk holes to the original battery brace.

The Y-max shines were the Yz2 may struggle when traction isn't optimal. My local rack also may run gold dirtwebs or even barflys however if the track is damp, slicks work very well also. However if the track is a little dry, the slicks don't work of course and this is where a stock Yz2 would struggle, and where the Y-max does well. The Y-max doesn't lose the pace when traction isn't ideal. Where the Yz2 must have really good traction to be on point.

Thank you Sir for the info on this.

Would adding more weight to the rear of the buggy help vs changing the Diff housing?

A lot of us have added weight to the rear (up to 100g) with no prevail. From those I have heard doing the swap they were excited with the performance. I heard through the rumor mill that Factory RC should have a conversion kit (minus the transmission) for all YZ owners to convert the cars over. What is great about the kit, is really 2 screw hole drilled and its bolt in. There are other things I have done to mine but not really necessary.

You could do this, but part of this change is raising the transmission parts and motor height CG. This provides much needed weight transfer, increasing grip.

Sounds like to be safe have the Max setup Diff and brace on hand if the tracks you go to is low bite.

What is the Cost to change this 10min job over to Y-Max?

Is the inside gears the same for max diff housing?

Thank you

Sadly the only thing that will carry over is the idler shafts, bearings and diff. Topshaft and idlers are different.

Cost-wise I would say you might be in it around $100-150 depending on option parts you buy but your car would work be the ultimate all year work horse.

Basically going in and coming out the rear never settles. So you lose acceleration and consistency of handling.

I think it has more grip than say an xfactory mid and a little less than a b5 mid motor.

I compensate with a square pack, brass front and rear bulkheads, and weight behind the transmission 1/2 oz, and under steering rack 1/4 oz and it works fine.

Granted not as locked down as a rear motor in loose stuff.

Put the ball diff in it and add weight and you'll like it a lot.

Just found this online. Factory RC has a decent list of what's needed and appears to have a conversion on it's way: HERE
