in dummy terms what does that mean

it means that when your car is being built, there is a WIDE variety of springs sitting at the factory. They select the 4 springs that are the closest to each other to give the car the correct balance and ride , and install them

every bonneville has 4 computer select suspension RPOs on the car.....

Means Pat is faster than me on somethings and has too much RPO studying time on his hands.. :P

Fargin... friiisdkdk$%#^$#^ scooped me ... freaking curse is gonna get him.......again
