More importantly, the dots on the bushing need to be on the outside. It doesn't matter if the number 3 is upside-down or not as this affects only the roll centre, and not toe-in. If the dots are inside, that's the reason you're getting less toe, instead of more.

Just make sure those dots are on the outside and you'll be good to go.

ok, I am missing something here because this is not the case.
Here are pics of the pills with numbers upside down. The arrows points to wheel so each of these would be in the right hand rear as if moves the pin out toward the wheel to toe the wheels.

no matter how I install the 3, it gives less toe than I can obtain with the 2
If what you are stating is true, then using the 2 as I do, I guess I am getting 4˚ toe?
My hinge pins rest down and outside with the dots on the inside

made with 6061 aluminum and clear anodized, this part allows you to simply

center diff. this will make it much easier to change diff fluids and inspect
the drive pins.
the kit also contains custom made delrin brake cam bushings for long life.
These bushings will not fit the stock center diff top plate.
awesome! Please make extra front ones and market for ebuggy
I need and extra front one

I've never seen a setup with the dots on the inside as shown in your pic. That's the reason you're getting less toe when using the 3o bushing as you've got them installed backwards.

Check the manual on p.16, step 8 - the 3o bushing is shown with the dot on the outside. That's how all of them, 2, 2.5 & 3 should be installed so that you get the toe angle which is shown on the bushing.

Do you have a setup station kit, such as the Hudy or Hard Racing? Just curious as to how much toe you actually have when the bushings are installed backwards? Anyway, dots outside and you'll be right.

No matter how you use the 3 pill, it puts the hinge pin at the center. The 2 and 2.5 can be reversed to add even more toe
Then I have to be running Low roll center with increased skid angle and 4 degrees toe and let me tell you, the mofo is planted

Regardless of what the manual instructs, if you're able to drive faster then that's all that really matters. I guess you'd also want to watch out for the rear arms binding up with the extra toe you're running.

If it works don't change it.

the no. 3 is on centerline. the 2 and 2.5 are off centerline.
if you install the 2.5 with hole rotated out then you will have more toe than
the no. 3 insert same with the no. 2 insert but you will have more toe than
the 2.5.

It was definitely "looser" on 3 degrees.
I get how K's inferno setting guide states it and I could be wrong but I do not remember anyone mentioning this in the MP9 forums.

Could this be a topic not yet touched on?

not sure what you are talking about here. If you are referring to the front
block to use on the E buggy. Right now it will not work as there is not enough
room to get the diff to turn out of the rear bearing fit, but I am looking into
it for the E buggy also. I would probably have to make a new rear block also.
but I think it can be done.

The issue you're having is you have Left-Handed bushings in the Right location. If you flip the arrows on your picture, the bushings make perfect sense (installed in the left rear).

no matter how I install the 3, it gives less toe than I can obtain with the 2

You can run them this way, my assumption is the 2.5 bushing backwards would give 3.5deg rear toe in, and the 2 bushing backwards would be 4.0deg rear toe in. I guess if you're driving on ice...lol.

If you normally run a setup such as Cody's 2010 WC setup, I would change the pistons to the 8 hole-1.2 pistons and use 50losi front and 35losi rear. That is of course if the track is relatively smooth like most indoor tracks with high bite.
