Are these the right pins for the ISS suspension on the xt8?

Bren speaking of tuning aid on the OD41 up front, at the last race I decided to race without the OD41 due to the track being very rutty and plenty of pot holes.

Now my base setup on the diffs still remained the same as 5/5/2 since 5/7/2 was not manageable on the track being so rutty.

My first question in relation to the OD41 pulling up front in rutty conditions is to use heavier oil say 5/4/2 and have the front pulling power but without the twisting action of the OD due to ruts etc or is that not applicable.

Second question would be related to track being severally blown out would going down in the diff oils help say 4/3/2 or 4/3/1 without risking of cooking the diff oils in 45 min finals and race temps in the 35C.
