The set-up JP gave you in the other thread for BMS for the Phenom will work at Hunterstown use 1 1/4" rear stagger. I'd start the T-7 on same numbers with little less cross, Hunterstown mixed new clay in with the clay they had, so it's a bit of a crap shoot for everyone, based on years past you'll need 60 cc Internal with a Medium base prep ( LS 2 and or Flip Flop medium worked well ) until the race starts then a hard base prep ( LS 1 ) day of the race. Depending on how good the track is you'll need a 14 & 15 front driver.
Good Luck !!
