This one?. That spacer goes between the rear brace and the suspension mount. Raising the trans also raises the rear brace that bolts to the suspension mount, so the spacer fills the gap

Ok, That makes sense. I had picture the rear spacer going under the RR block.

Looking at the pics of lee's car, is that the truck front bulkead? Does the front servo placement look different? Looks like a lot of space from the front of the servo to the rest of the steering linkage. But maybe its just the angle.

I got the same impression. It looks like he spaced the servo back and then added a spacer on the horn under the ballstud to get the right angle.

Ya I see the spacer now. To me though I feel like that chassis is longer. I think that is the truck chassis, with the truck tranny and truck front bulkhead. I don't think its the truck front arms because I feel like that would be too wide. But my reason for the other stuff is one, you can see the hole in the middle of the front bulkhead which I only find on the truck version, and the spur gear guard on the tranny, which seems to only be on the truck version, but I don't know.

Now I'm unsure if the truck chassis really is longer, but he has all that space up front, a full size servo, a large ESC with a cap sandwiched in between and room to spare before the battery. My buggy has room to spare before the battery but no real estate in front of the servo, and despite running a half size servo and a small esc and receiver in comparison to his, its stacked all against each other.

It is the truck bulkhead, as it's quite a bit beefier and direct swap for the buggy part (with minor trimming to the body). On the current setup sheets they are all running the truck steering rack with the short bell cranks which could account for the extra perceived space in front of the servo. I tried running this steering setup this past weekend, and with the .5 offset truck steering blocks it really does change the steering feel and I like it.

The team is currently testing a new transmission that looks like the truck trans (split case). With this new trans, you have the ability to raise the diff (similar to the truck or 4wd). Since we can't do that with the current production trans, we use the shim kit and raise the entire trans, not just the diff, 2mm. It's not the exact same thing, but it's as close as you can get with the parts available.

So looking again at this, trying to see if I want to pick the parts up for it, I noticed that the bell cranks were aluminum, not plastic which comes in the yz2t kit. Maybe they have pre produced some? Or is there another kit with short bell cranks that are aluminum?

can you comment on how it felt change-wise in comparison to the stock setup?

negatv1, might you also have a parts list of what you changed to?

I was wondering that myself. Is it possible they're
YOKZ2-201BA2?

Basically just parts from the YZ2T steering parts tree. The rack, the short bell cranks, and also the steering blocks (either the standard or .5 offset). Similar to the CAL2 setup.

There are 2 versions of steering bell cranks.

#Z2-201CSB carpet verion, normal lenght pivots
#Z2-201DSB dirt version, +2mm pivots

now you can mix them, take dirt akermann plate and carpet pivots, so you do not need to put 2mm under ball studs to have
the same geometrie.
Thats all.

So nothing really new up in the front of the car, except they put the link from the servo tie rod now on the pivots, to make an even faster steering.

In the rear its a brand new lay down carpet tranny, nothing to do with the truck one, except raising the diff without spacers.

The Eos track was big, without very tight turns, so they used the 0,5mm akermann plates. On tight tracks the old carpet ones will surely be used.

The truck bell cranks are part of # Z2-200NT, which also includes the center link.

We do not use plastic steering parts on carpet, or high grip.
To much bending and not so crash resistant.

btw. these part no. are complete steering, incl. center link
