Most cars don't have their ackermann adjusted properly to use a spool to its potential. 17.5 and mod TCs have enough power to get around it but are still being less efficient. Too much ackermann, which puts too large a slip angle into the inside tire coupled with a driving the inside wheel the same speed as the outside, and you'll get a large negative longitudinal force reaction.

What would be a good weight to start off trying in a gear diff?

Start off with 55 wt (725 cst ) oil. If you get too much steering (or you traction roll) then go with higher weight oil.

That's all? I was thinking upwards of 250-500,000wt.

Are you talking about a gear diff in the front? If so then you would want to put 1 Million cst (or 2.5 Million cst) in the front gear diff. Check out this web page for those heavy silicon oils --> http://www.teamgravityrc.com/store1/...=0&sort=normal

That depends in part on your driving style (and the brand of diff, of course). I use oil that is just thick enough to give some stability under trail braking. On my car that is about 10,000 in the front (filled full). The rear is a ball diff.

Yes the front diff, I run 2000 in the rear.

i liked 100,000 in the front diff it's gave enough not to bind in the corners and had great steering. for 25.5 I don't think you need much more.

I tried a gear diff in my winning tc6.2 vta up front and ran 100,000 AE . Ive never used one up front before but it worked great in my USVTA ride. I run 40 AE in the rear

Me too! any word? Want to get anotner ESC for another class, but if the Gen2 is approved for Trans AM, I'd get it and just switch between the two cars.

Perhaps a better question, who should be be asking about this?

I would also like to know. I used the gen 2 stock spec in vegas for the spec gt class, it worked great. I would love to be able to use it for VTA.

I changed my browser to Firefox and installed the ******* Plus add-in (free). This eliminated most of the annoying pop-ups/ads on website and allowed my older/underpowered Windows 7 laptop to browse much better.

I understand sites like this need to generate revenue to exist, but do it in such a way that it isn't an annoyance. More in this case certainly isn't better.

If the Tekin does ever get approved, I sincerely hope there isn't any way to mess with the firmware (in other words...cheat).
