Super high bite sugared track with slicks I like the slipper. On any other track I've ran it on I like the center diff. Felt some fade using the center diff and 300k, will try 500k or more but slipper felt more consistent.

indoor med/high bite with bigger motor, gear diff. 200k feels better than 100k. Have not tried higher fluid yet.

I have a slipper in in now with 17.5 , better for the no motor issue.

The gear diff is lighter than the slipper though.

Thanks a lot for responses! I run in a med bite indoor track that's pretty slick. U guys think the gear diff would put down the power better than the slipper? I'm running a 5.5 turn . I was hoping a gear diff would get me some more bite?

I ran the new 2015 yesterday for the first time and it was excellent. I built it with the center gear diff w/ 150k oil and ran that for all of racing and tried the slipper after. The center diff was good but felt a little inconsistent and didn't have great drive out of the corner. The slipper felt much better out of the corner and over jumps, but the diff felt better in bigger sweeping turns. Overall with a non super high bite track I think the center diff and higher diff oil (300 or 500k) will be the most ideal, the 150k just wasn't thick enough.

Im using the gear diff. I had 100k for a medium grip track. Went with 500k when out track changed to a much higher traction surface. I really like the 500k. The car is a lot more responsive on throttle.
I have thought about trying 1,000k but I dont have any...

anyone make a billet diff case,the top half where it attaches to the shock tower is pretty thin and it breaks off to frequently for triples and other big jumps on hard clay

Yes I think the diff will help put the power down better, especially when running the shorty setup.

Got my '15 together in time to race it this weekend on medium grip medium size track running center dif at 500k. One thing I don't miss with the slipper that the center almost completely eradicates is the rear coming up on hard braking at the end of a straight or speed section. I also find it delivers the power more smoothly with less jarring than the slipper. I always ran my slipper fairly loose mostly to ease strain on my tranny gears but I'm sold on the center dif, best $60 I've spent for the car by far.

I just have to say, I ran on a outdoor track with med bite, I was running m4 holeshots, I only had to raise the car a bit and used 1 dot rear springs and the car was really good. I find I like driving 4wd on lower bite tracks a lot more than the high bite indoor, I had a hot lap only .5 sec behind the fast guys, but couldn't get a clean run in.

I installed the t bonez bumper, but I trimmed it down to similar size of the buggle boy one, and it worked great, it kept the dirt from packing up in the front hingepin mounts, and no bent FF even on some nose dives.

IF it is the front you have trouble with something like this will help you:

We run it and haven't broken a front diff housing since we started using it.

will 300,000 in center diff be ok for a med bite loose track?

I think 300K will be a happy medium. If your tracks bite condition ranges from loose to med. I think you will be happy with 300K. Have you tried 200K? It works well on a track that presents loose to med bit conditions but I think a higher weight will be better and thus be more consistent.

If you want to create a custom weight diff oil thus can be achieved by combining different ratios of differing diff weight oils. There is actually a conversion calculator you can use. In doing this I would highly advise one never to mix WT(oils) with CST(oils). It is also a good idea to use the same brand when mixing.
For example if you have bottle of 200K diff oil and lets say a bottle of 300K thus you can mix them together using the proper ratio to obtain a custom diff oil weight in between 200k to 300K.
If you wanted to make 10ml(cc) of 250K diff oil you would use 55% 300K being 5.5ml(cc) and 45% 200K being 4.5ml(cc).
