Hi everyone,

Well, I just finished making all the parts for my centre differential conversion and am going to post a full step by step guide of the installation. Hopefully it will help anyone wanting to do similar to their Gmaxx's.

Okay, so here i've got a pic of all the parts needed for this install (the diff is an Xray XB808 centre diff with a 42t spur gear on it):

As you might be able to see, i have shaved the top and bottoms of the CD mounts down to lower the diff into the chassis a little more. I have also drilled a hole through one of the diff mounts which bolts to the motor mount too to help reduce flex. I am using two 3mm plates of carbon for the motor mount, again to reduce flex and hopefully prevent the stripping of spur gears.

Now that the motor mount is put together, the diff and top plate go on, nothing too complex here...

Now for the installation of the bottom plate, this is probably the most important part, because if the diff is not mounted in the exact right position the spur might hit the x-braces when on the chassis. Also important to countersink the screw holes so that the diff assembly can sit flush on the Gmaxx bottom plate:

With that done, you can install the diff assembly onto the chassis plate. As you can see i've had to drill 4 holes in the lower Gmaxx plate to mount the assembly:

I've had to cut out another rear upper plate so that the 1527 can fit with this setup. obviously with a 1515 sized motor i don't think this step will be necessary:

Nearly there....

Now with that done, the chassis plate with the diff assembly can be put back in. Again, it is pretty important that the holes in the lower plate for the diff and the chassis plate were measured properly so the diff sits central between the x-braces. With the 42t spur i have no problem with clearence between the braces!! No need for any dremeling there thank god

Now all thats left is to put in your motor!!!

I also redid the front of the shell (again), now its got the CF grill and pink badge, very STI-ish i think:

I hope this is helpful, it was an absolute blast putting it all together. It had its fair share of unexpected twists, which is why i finished it a week later than i thought i would. But hey, hopefully now you don't have those problems!!!

Any questions/comments/criticisms welcome
