Oil for TC6 geardiff
My Spec-R diff was built as per instructions with a 1000cps oil,works flawlessly and doesn't leak at all. Didn't even thought about having the need to use green slime.
The new TC6's differential i got included the new graphite gears instead of Delrin ones, i wander what's the difference between the two matherials.

That's for high bites tracks I presume?
I looked at a lot of setupsheets from different drivers and they almost all use thiner gearoil, like 35/40/45wt on low, medium and medium+ grip tracks. Some even on high grip tracks.
How does all of that sounds to you?

cSt - Centi Stokes; cPS - Centi Poise are the same!

The newer Associated shock/diff oils show their cst values right on the bottle, which makes life a little easier. So, 1000cst AE diff fluid is actually 1000cst. No conversion necessary. Here are the cst values for various AE shock oils:
22.5wt - 238cst
25wt - 273cst
27.5wt - 313cst
30wt - 350cst
32.5wt - 388cst
35wt - 425cst
37.5wt - 463cst
40wt - 500cst
42.5wt - 538cst
45wt - 575cst
47.5wt - 613cst
50wt - 650cst
55wt - 725cst
60wt - 800cst
70wt - 900cst
80wt - 1000cst
22.5wt - 238cst
25wt - 273cst
27.5wt - 313cst
30wt - 350cst
32.5wt - 388cst
35wt - 425cst
37.5wt - 463cst
40wt - 500cst
42.5wt - 538cst
45wt - 575cst
47.5wt - 613cst
50wt - 650cst
55wt - 725cst
60wt - 800cst
70wt - 900cst
80wt - 1000cst

Having run 1/8th offroad for several years, I've felt the affects of tuning diff fluid weights. It should apply to the touring cars too, but I've only done one test so far.
In general - If your car seems to be hanging up in the center of a corner and not wanting to rotate, then changing the rear diff fluid to something lighter will help the rotation. Further, if the car gets loose on corner exit when grabbing the throttle aggressively, that's another sign that lighter diff fluid could be used in the rear.
If the car is loose on corner entry, then a heavier diff fluid is worth trying.
However, since I HATE changing the fluid in gear diffs, I'll go with something that works in general (sounds like 1000cst is usually favored) and use other means to adjust corner entry/center/exit instead.

This values are very different of the xray's ones

Hey guys,
Just thought I'd chime in here regarding the diff oil discreptancies you guys have been talking about.
One of the reasons why you are seeing setups with 1000...and some with 30-40 is because the AE gear diff internals are different than the spec r internals, resulting in a different feel with the same oil.
This was done in part so that the range of oils needed for the diff could more closely coincide with the oils used in the shocks... so you don't need to carry around 30-50 in 2.5 wt increments for your shocks, and then 80-90-100/1000Cst, 1250 cst, etc for the diffs.
When using the spec r gear diffs, most of the guys seem to run oil near the 1000 cst mark... when using the AE gear diff, it seems like most guys are running 30-35.
Hope this helps clear things up!

I don't know if the SpecR TC6 gear diffs build up any differently from the spec r yokomo gear diffs that guys have been converting/using up until now.
Sorry about any confusion!
Last I hear on the AE gear diffs was that they were getting very close to being ready... but I think Rick will have better information regarding that than I will!

Well think the same, sold my TC5 and put back TC3 on the road since.

Hey guys... I am looking for a good starting spot for a medium size/medium bite carpet track. This track is next to an offroad track(both indoors) so it tends to get a little dusty at times.
Sweep OG Spec is the spec tire w/ Paragon Ground Effects as the only allowed traction compound.
Looking at the Associated website, most of the carpet setups are 10-12 months old... and prior to the arrival/use of gear diffs in the car. Im open to using either the ball or gear rear diff, but was wondering it anyone has a good baseline for me.
Thanks
