I moved my battery to the center line so left and right weights are the same with a rear weight bias. Really works well for me. I also tried 37.5wt oil front and rear with the 2 stage pistons. Our track is tight blue groove with no big jumps and heavier oil keeps it so planted it's crazy. Cut 1.5 - 2 sec off my lap times for a 25-30 sec lap track.
