It comes with a 2000ct I think a review said. I'll wait and see if it does but a 2000ct is that equal to 200000??

No, there is no numerical conversion involved. It's the same unit, so 2000 is much different from 200000 (or 200k, to make it easier). 2000 is what you would use in a rear diff in a 4WD touring car, for example. While in front diffs, much higher numbers are used (up to 2.5 million).

2000 is pretty thin. Flows like motor oil. 200,000 is like maple syrup. 500,000 is like maple syrup on a really cold day. (You scoop, rather than pour it.) 2.5 million is damn near putty.

Yep, I agree with moneyracing. 2000 is too loose. You want somewhere between 50K to 100K probably.

Think for asphalt that 100000 is enough???? I guess you want some looseness to it while on pavement right?

Hard to say, we dont know how you drive.

Okay, have a question,

at my last race I noticed, that although my car handles great the front tires seem to be really scrubbing around tight corners which slows me down. The car stays on the track like its glued to the track ...rear end stays put and it handles great.

I don't have time to get any practice in and experiment before my next race, so am going to try my best guess at what I should do and/or recommendations in the first qualifying heat of my next race. If what I do works then great, otherwise I'll go back to my current setup which is good ...but just looking to see if I can improve my speed around corners.

Here is what I have:
Tamiya M05VII (as many already know), Tamiya 54000 shocks w/ Red springs up front and yellow in back. Shock oil is 25w all around, and am using anti-sway bars front and back. (don't recall offhand what spring tension on front back) --but I believe medium all the way. S-grips in back and Tamiya A slicks up front.

So my front end is a bit softer than the back end, but only slightly. Would it be best to soften up the front even more -maybe a lighter oil weight and lighter sway bar or no sway bar up front? i am thinking if I can get a tad more chassis roll up front that would help my front tires continue spinning around the corners rather than pushing/scrubbing...thoughts?? Maybe I need to let off on the throttle a tad more around tight corners?? my car is competitive, I am almost always in the top 3 spots ...just can't crack the 1 or 2. (I race w/ some B main TCS guys ...so pretty competitive group).

Ok thanks

The ones I found did say touring 1/10 tires so probably not I will keep looking and see what I come up with.

Has anyone ever used the 3 racing gear diff oil....it says in the description that FWD racers may use weights of up to 100000. So Im not sure if it's going to be heavy enough because they don't give a weight in the description. Any recommended brands to try for the gear diff fluid?

CST is cst. Get the brand you can locally get, and then stick to it. I found scott's old pdf. It's a good starting point. I used my carpet setup outside with plenty of success. Ran the 2200kv spec motor and a 21.5 Mach II

I encountered a similar situation in the past. I was able to fix the issue by switching my inside front camber mount from the "top" hole, to the "bottom" hole. Hope this helps.

What surface and grip level?

I think your setup is too soft / too much roll. Only a guess though.

Ivan

Diff setting is important. And the amount of droop you are running Should be minimal but with no pre-load on the springs. I'd also be tempted to remove the front bar and fit the stand-up shock tower if you haven't got it already.

Great suggestion, will try it out.

I have the standup tower already, but like the idea of running w/o the front bar and see what happens there. yes, playing w/ droop too.

We are running on higher grip asphalt. Hmm, my setup isn't too soft, or at least it doesn't seem?? ...yet its worth a try to make it stiffer.

....
so looks like I have about 4 or 5 great suggestions to play w/ ...this should keep me busy. Thanks ..will let you know what I find.

sosidge,

you said my droop should be minimal. right now my cars arms angle upward a decent amount when the car is resting at normal position. ...i'll try reducing the droop a bit since I do have quite a bit, i'll see how that does. Thanks for the tip ...yeah, thinking maybe I dont' have enough shock travel as a result too. ...k, going to play w/ that.
