Thanks for the two responses above. I'll prob go with the 8x1.2 square or tapered pistons for now (don't have a tap yet). Would love to try 8x1.3. Will order a tap. I was thinking if the tapered side was down, rebound would be faster. Is that not correct?

I'll increase the rear shock spring (springs are v2) to pink, I think. When I look at setups, it seems the front springs are about as stiff a they can be and the rear springs are about as soft as they can be. That confuses me.

Just installed two of the 3 diffs last night. I do have v2 gears. I kind of like the way the diffs are, but I did like that center increase from 12 to 15 so I might take them apart. Idk. Other than the rear, it's close to what the team drivers run.
