HI, i guess that's the thing that keeps bringing us all back to the track.. all the tweaking possibilities..

I've got a Sportwerks .26V2 with a Dynamite Platinum 053Midrange pipe, Sidewinder fuel, and O'Donnell 99 plug.. running stock ss carbon clutch shoes with stock springs.

My local track is red clay/dirt that when dry, makes a blue groove after a few heats.. It is watered once a week (indoor)

I noticed when I went to a lighter rear diff oil that the truck would "rotate" through the corners better, the fronts got some bite and the faster spinning rears threw the rear end around the corner...(at first it did feel like a drunken sailor, but quickly learned when/what made it get tipsy) I have to admit though that it was also adjusting the radio and mastering 'expo' on the radio that allows my acceleration through cornering to be more smooth.. I am a 'digital-driver' , a typical begininer driver with the throttle or steering reactions "all on, or all off" .. need to work on being smooooooooth...

I haven't experimented with lighter in the center.. But I just might go heavier, as I went up a tooth on the clutch bell, from a 13t to a 14t, and now I notice the fronts really ballooning into rubber bands if I jump on the throttle too much.

Look in the HF INDEX, my setup sheet is posted there.
