I run 7k front. 5k rear, 10k centre in My On-Road Buggy I'm thinking of removing the centre diff entirely though and making an alloy spool to hold the drive cups and spur, it handles well as is, but my front tires do wear more than the rears so they may be unloading and spinning, it would save a fair bit of weight too.

Have a look at serpents, kyosho evolvas and the like they don't use diffs at all, and there scary fast.
