Just installed a set of H&R Sports springs on my '99 Civic SI with stock struts. The drop is a little more than I expected but it rides great. I just volunteered to car pool twice a week and when two passengers sat on the back, the added weight considerably lowers the rear thus adding more pressure to the shocks. I'm worried that the rear shocks will blow soon. I will be car pooling for the next three months, what would be a good set of shocks to replace all my stock ones while also help reduce rear sagging when I have passengers. I've seen adjustable sets that make the shock firmer such as KYB AGX's but not sure if these types of shocks can actually help reduce the rear from sagging when I load up the car. I'll consider anything from adjustable to "heavier duty" shocks so any suggestions will be appreciated. Thanks

 

The dampers have nothing to do with "sag." The dampers simply provide resistance force in two directions (compression and rebound) to control the velocity at which the suspension moves. The springs control the distance that the suspension moves.

The only way you can reduce the sag under extra weight is by using stiffer springs. Or carpooling with slimmer coworkers.

However, stock dampers can't control spring rates that are significantly stiffer than stock.

Edit: I cn't speel.

 

Well explained. Thank you. The coworkers are fairly slim anyway. Seems like any weight on the back just drops the rear end a bit. I'll keep an eye on the shocks until they blow and just replace them with a better set that's designed to control the stiffer springs. KYB AGX's seem to be a good match for the H&R sports from what I've seen around here.

 

H&R Sport springs are pretty soft for the amount they drop.

With passengers in the back, I'm betting the rear suspension will bottom out on the bumpstops, no matter what shocks are used.
