Spur
No, the drive on the high grip sections is better, the front wheels dont spin if the traction is there.
On the dirt the front does spin if the diff is set too loose, but it is very easy to dial out.
Parts taken out are spur and slipper pads.
Parts used were: 78 tooth Kimbrough spur, the ones for pan cars.
Drilled out ball holes to accept 5/32 ceramic balls instead of 1/8.
Bearing inside of spur is a B4 idler gear bearing.
Diff rings are Tamiya, from an old on road solid axle rear end, also found that original rc10 'six gear' diff rings are large enough as well.
Method was simple, mount a slipper disc on a bolt, spin them in my drill press at high speed. Use a sharp drill bit tip to carve out a groove to hold the diff rings. Works very well surprisingly.
Put together with minimal lube on the balls.
Lots of black grease where the thrust bearing would nomally be.
I'd believe that this would greatly increase the handling of a stock class racer, probably more that a mod driver.
I'll get photos next week but it really is very simple.
