25g Nose heavy only used the front-most, 2 bulkhead screws in the front top deck. removed 1.0mm from outter upper arm shims removed 0.5mm from inner upper arm shims removed 0.5mm from inner lower arm shims all of these together equal a fairly large 1.0mm lower roll center all the way around, and will leave u room to move the upper inner arms up and down to tune in to the track grip. u will probably end up around 3.0 front and 2.0 rear upper inner arm shims. 10k rear diff for VTA or TC and 8k for TC or LMH test leaning shocks in from 3mm shims to at least 2, i would recommend 1.0mm and if u feel that is too far u can back up some. but id rather u go too far to help save u some practice/ test time which will be valuable. talk to EA or Kemp about how much sidewall glue they would suggest u run. i have 59.0 mm on here, but if Kemp and EA say higher, go with which ever one has the highest number. If 59.0 is higher than what either of them said, go with what i said to start.
