currently using 300k upfront and 1000 in the rear. ie thinner oil for low traction conditions and thicker oil for high traction conditions.
At the rear 1000cps is the best compromise, for high grip track or very hot temperature 1500/2000cps, for low grip condition or cold temperature, best 700/800cps.
At the front is good 1000K, also used Putty, but for me no constant operation.
