why does everyone run such thick oil in the center diff? i came from a d413 and yes i know its a different buggy but ran 60k in the center, 100k on higher grip, so whats the reason for 200k plus, you would think at those thicknesses you basically have a spoool

also i think you will see thicker oils in other cars once people catch on a bit.

All cars use different designs for the diffs. Tooth count, clearances and volume all change what oil is required. It's just like shock pistons. The Xray takes heavier oils.

exactly, the car tends to be on the heavy side, depending how you set it up. so that inertia calls for thicker oils. I run like 400-600cst rear and 600-800cst front shock oil depending on the surface. that comes out to like 50wt-70wt, usually most cars run more like 30-50wt.

Lighter oils with yatabe springs on carpet are $$$

On low to medium grip clay what is better big spacers on top or bottom of caster blocks?
If anything, once warmed up, the diff seems a bit soft.

Ran 78/27 last time out but motor was still extremely cool, around 105 degrees after 7 minute race. Will be bumping up to a 28 next time out and see how it goes.
I do have a fan on the motor and using a trinity d4 1s 13.5.

It really depends on your driving style too as far as center diff . If your reall aggressive you shoukd go with the 1 mil . The softer the fluid the easier to drive . You just gonna lack forward bite . Its just like a slipper thicker oils is a tighter slipper thinner is looser .

Ran 500K on outdoor blue groove with dusty edges outside the groove. It was perfect. Ran it on Med/high bite clay with electrons... much prefer the slipper in that case. Have not tried 1mm

110% true. Ive been saying this since the 15spec. I can run 1mil all day and maybe get a faster hot lap but with 500k ill run a much faster 5 or 7min run because the car is just more consistent and easier to drive. normally Ill run 7k,500k,5k or 7k,300k,5k at AMS and other tracks nearby.
no comparing a center diff to a slipper no matter the oil.
also 500k-1mil works perfect on anything med-high bite, typically clay surfaces. carpet i much prefer the slipper. but on any dirt surface i much prefer the center diff .
