If the car is used as wagon, the 1.03 are a good start, you will need to address rear leafs to maintain any kind of balance, which on a wagon must be kinda tough, empty to fully loaded.. Personally I would step up at least a bar size, stay away from KYB's period, nobody has ever said after years here on moparts they went too large, and most wonder, even with the noticeable improvement of whatever larger TB they picked, if they went big enough.

Be sure and followup you results, BTW.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
