Fellas! I have a SRR and my buddy has a SBR and we have a blast with them because they can slide so beautifully and what not. They handle so differently than arrmas so it's great to have them as well. We both already locked the rear diffs which made sliding so much better.

Now we are trying to determine if locking the center would be beneficial or not. Just can't quite wrap my head around it but I feel like it would help. Opinions?

I like how my UDR drifts with a locked rear and open front and center diff. Locking the center will make the front wheel with the least load spin at the same speed as the rear wheels regardless of which tire has the most grip. With a center diff the wheels that have the least amount of grip will spin the most. You can tune the difference in wheel speed by adjusting the differential oil weight. I think the UDR has 1 million weight oil in the center diff which is almost locked.

CD's help it to not spin out. If you need more slide, go heavier in the CD.

Just out of curiosity do you have a Mojave as well? Just wondering your opinions on them. My buddy has a Mojave and SBR and UDR is next on his list, they seem pretty sweet

I do not, I bought the UDR because I wanted the realism of IFS and a 4 link in the rear. It drives unlike a conventional RC but it is so cool. IMO it may not be much different than the new SBR

Locked rear and it WILL drift all day long, on demand. :giggle:
Your call. Depends how you want it. When locked however, it will not drive best for technical driving. Driving skill to adapt to it is a given.
You probably know this anyway. Trial and error what works best for you.

Excellent description! I’ve been struggling for a while now to understand diffs, oil weights, LSD plates… 🤕 And this info gives it all more clarity! (y)
