Break them in and adjust them EXACTLY specified in the manual - they will work wonderfully.

But can the FACTORY outdrives/bearings and such handle beyond 4T brushless motor?

I am just running 12-17T's now and burning them up.

Please let me know what i am doing wrong? or does anyone have any complete DIFF's for sale?

It could be your driving style, is it possible that you are a throttle jockey?
Maybe try to be a little smoother on and off throttle.

change your throttle curve on your radio, that might be easier on the diffs.

I used to run this car back in the day. My experiences were:

Composite outdrives will melt down running modified. You will be lucky to get them to survive 19 turn racing. They are excellent for stock racing.

The stock steel outdrives were not the greatest because they did not use a d-ring making it very hard to get the diffs to lock.

IRS made a decent outdrive and I believe they are still making it. They had the best I could find and a lot of the factory AE guys were running them back them.

Hardcore and Robinson Racing made some also, but they were also not using d-rings.

A lot of the problems come from set up and throttle finger also. Modfied requires a smooth trigger. Not saying you do not have one, but it is something to keep in mind. Set up is crucial for a long lasting diff when running modified.

Hope this helps...

I respect everything you just said but ... my finger isn't the prob i don't think... i don't use D rings, i use aftermarket O-rings with Alloy out drives but to be argumentive i burnt the factory ones up too. so if it's just MY car and noone else's then i guess i need to get a new set up!

I have added alloy body mounts and alloy wheel nuts to match the TA blue team factory effect .. but anyways ...i just need some help here!

tired of sinking $$$ into it

generally they are not a problem as long as they are set so they don't slip but are still free to spin (otherwise you may as well use a spool!!!). Make sure you use heaps of lube becuase that will also keep the temps down.

As said above the kit instructions are pretty good but they are not always 100% and you have to make sure you do retighten the diff after a couple of times on the initial try.

I usually check that my diff isn't slipping about once a meeting anyway as it takes power away.

Anything more than 27t and I had the same problem

I too followed to instructions fully, changed car in the end! I was going to get the alloy outdrives, but thought its better to spend that money on the new car.

I wonder if they sell differentials ready made? it might take the pain away of building one and making sure its set right.

this past summer when i benched my rdx, i ran some mod with my Tc3 w/ all composite diffs. i ran an 8x1 with no melting or slipping. just set the diffs right by the book and you should be ok. the only diff halves i broke was because i jumped the car with the 8x1 in there.

good times

-Zac
