You can try a couple things if you’ve got too much grip and the car is rolling.
First is just simple throttle control with your finger as you turn. And braking.
Raise your roll center by lowering the camber links on the tower. Try just the rear first and see what happens. Then try both.
Move the rear shocks to the lower hole on the tower. Again, try the rear first and see what you think.
Thicker oil will help as well, but that will take some experimentation and there’s too many variables to say what a good starting point would be.
You can also dial out a little drop in the back. Only takes a millimeter or so.
Try sway bars.
These should all help, but may not eliminate traction roll entirely. When this happens and these things aren’t sufficient, it’s a sign you’ve got the wrong tires.

Having trouble with my diff. Nice and smooth but when I opt down the crown gear it locks up. I have done it dry and filled. I have rebuilt it about 5 times. I have inspected the parts and see no defects. Never had this happen to me with a fluid filled diff before. Any ideas?

There is a trick to putting the cases together that is shown on the LC youTube page where you wet sand the top of the bottom part of the case to give them a better seal, but I dont know if this will help you. You could just have a defective case or something too. My best advice is to contact whoever you bought it from and they should help you resolve this. Warren RC is particularly good about this kinda thing.

Anything is possible. A manufacturing defect is not exactly common with these cars in my experience and from what I've seen, but it's also not unheard of either. You've got enough experience under your belt that would lead me to believe thats very possibly the case, especially since the other one seems to be perfect. I had a faulty machined shock body on my kit which caused the piston to bind, but that was resolved quickly through Warren RC.

I mean, shit happens. It’s not unheard of. It’d been over 20 years since I built a kit, and I have to say, even with my limited experience building them, the LC kit was a real pleasure to build with no big issues. Aside from the weird shock body thing (which got resolved quickly and painlessly) there were zero unpleasant surprises in my LC12 kit. Parts were organized into their respective bags, clearly labeled, and nothing was missing. The manual was clear and well done with each step being well illustrated. If the some of the things I’ve heard about a few big manufacturers current kits are true, the LC kits are a cake walk.

Is there a floating servo mount for the 1/14th scale or is it only for the 1/12th scale?
Pretty sure my servo gave up the ghost tonight. It's taking no input from the receiver and will only center when moving the tires from one direction. I'm wondering if this is why I hit LVC last night in less than 5 minutes while my battery showed 40+% left. Maybe as it was dying it was drawing a ton of current and pulled the voltage way down?
If the floating mount will work on the 1/14th scale does anyone have servo recommendations?

Yes, the floating mount will work on all the LC 1/14 models as well as the LC12. There are way too many 35mm wide mini servos to list though. I'd suggest going back through the thread, or doing some googling to get an idea of what you might be interested in and ask about them here.
Just a few models that would work and will give you a starting point would be the SH series of Savox servos like the 1250, 1257 and the 1350, the Align DS535, DS530 and their metal case "m" variants, and the Trackstar TS-P12s.

I think I'm just going to give up on the ball cups and try ball ends instead.

Floating mount is now ordered. Did some servo research today but still not sure what to go with yet. I have a set of Hitec 225MGs in the basement that I might just toss in there for now. Not digital but should give me a starting point to go off of for both speed and torque.

Made a typo above. HS-225MG is what I have laying around in the basement to test.
