Hey Marcos,
Will the a gear diff be overkill to use in a small track? or is well suited for a large flowing track?

tnx

Expierience tells me to use lower roll centers when I have a traction rolling issue, but we'll see how much traction the Gayte actually has. I'm bringing 2 cars for stock and one for mod (which I'm only running a 13.5 in).

In an acutal high bite situation I feel that the car will most likely traction roll in with the high roll center blocks on it.

Schreffler and I always run the medium roll center blocks and mostly in the low position on carpet and i have never once traction rolled my car and its almost always very good.

I ran the gear diff for the first time this weekend and it produced great laptimes and more steering than I previously had. My on power steering was increased tot he point where I lowered my Dual rate 20 points to compesnate.

It made the car roll more than with a ball diff and to combat this I put on sway bars a 1.4 front and 1.2 rear. It still needs a little tweaking for the setup to be perfect with the gear diff but I think it felt like there was quite a bit of potential.

Still running the standard spool up front though.

I see that your running the lipo chassis, did it really made a big difference between the 6 cell chassis?

Hi, has anyone had problems with the gear diffs?
My friend has already broken 2 of them on carpet in open 13.5, although it was just the "soft" lrp vector x11 stock spec 13.5 with gm genius 90 v2
The first one got broken after he removed shims, the seccond one broke after he has breaked it in on the table, till it felt useful. (but it never got too hot)
both geardiffs broke while running the first run.
Now we are using the spec-r diffs fpr the yokomo and they are fine.
But I have 2 u-pro geardiffs left and would like to use them in the second car, but what if the break in the first run, too?
Is there anything we have to keep in mind before using them?
How do you guys make it last even with 5.5 motors in it?
regards
Chris

It's important that if you take the shims out from behind the gear you put it back in on the outside of the out drive. I spent quite a few hours last week figuring them things out and found that they need to have both those shims or the diff out drive will actually push back in and bind the gear causing them to break.

How are you suppose to mount the weight next to the battery? They just kind of sit in there but are not held in. What is the way to do this correctly?
