the car is very good out of the box...taking nothing away from the TC6.1 WC...both of my 6.2's are better out the box than my 6.1 WC with upgrades...the dual joints from AE is the only real upgrade imo that's a must....the fan mount battery strap and belt tensioner are all great/neat upgrades...but not needed...
oh the AE servo saver is also a must...
