I use 1C-1C 1XA-1E suspension blocks.
The front dampers in the 2nd hole (from the inside) and the rear is in the 3rd hole.(I've got MR33 and HPI Springs but the Tamiya was the best one)
I dont know the value of MR33 B oil but i think it's about 700-800WT
I've got MR33,CS High Grip and Nosram traction fluid but i didn't tried the other 2 fluids.
regards,
Mate
