I will be going through the build of our Hellcat here! We are stoked to get the car and begin the mods! The following details our first round of mods. I'll comment on them as time passes. Mickey Thompson 275/40R20 ET Street Drag Radials - These are excellent for general cruising on a stock Hellcat. I highly recommend them. Good in the rain up to 80MPH. They do not like standing water at 70-80 and will hydroplane. If you see standing water, slow to 60MPH or lower. On a modified Hellcat, they are still much better than street tires but will spin obviously. These were our daily driver tires before mods. Love'em. Mickey Thompson P305/45R17 ET Street R's - We are now daily driving these tires and wheels, and they hook much better than the 20's. Once you drive a while and they get hot, they hook pretty well on the street. They do NOT like rain. Period. Drive slow, as they have no water channels. Weld 17x10" S77 RTS - What's not to like? Beautiful wheels. Metco 2.85" Upper Blower Pully ATI +10% Damper + pinned crank Gates K100572HD Blower Belt Unlocked PCM, Diablo inTune i2 and custom tune.
