This is a base model Caravan with few options, just air & tunes. (It didn't even have the drawer under the passenger's seat when I got it) This means it is about as light weight as these vans go.
Build Thread:
Current Mods:
Third seat removal
Roof rack cross bars removed
Aftermarket cone air cleaner with warm air intake
Mobil1 oil
Minor weight reduction
Wipers parked as much out of air flow as possible
Planned Mods:
More weight reduction
Lowering (it sits pretty high right now)
Performance exhaust (I believe the 2.5" cat from a 3.8 will bolt right in with the proper muffler)
Antenna relocation
grille block with possible below bumper air intake
Sensor tweaking per AutoSpeed article
