[Mr. Pink]

Tried my very crude centre diff mod yesterday.
Drilled out 8 4mm holes in a original spur-gear with 5/32 balls directly against the slipper plates.

My home track is high grip astro and I found it very easy and smooth to drive. But I had problems to get the car quickly around hair pin turns that is no problem with regular slipper. On medium turns and high speed turns it felt very smooth and stable. I am quicker with standard slipper on this track but it will be tested out on loose surface as well...

One thing that is affected is braking, as you can not brake as hard but on the other hand it is more stable under braking.

My mod did not allow any slip at all (soft alu slip plates directly against diff-balls). so it was the front wheels slipping instead, under-steering on power.
