Why does everyone say old cars need Hydros? Are you looking to vibrate the ever living shit out of 35+ year old car?! I've baged 2 of theses monsters. an 85 FW and my 95 FW. It's pretty straight foward install. Fabrication is pretty minimal if it's a basic setup. It's a lot more cost effective, a lot more comfortable, performs a lot better and a lot more RELIABLE. As long as the bag or lines don't rub anything the system will last quite a while. I've seen cars with over 140k miles on the bags that still work perfectly. I havn't seen a Hyro setup that hasn't leaked poped a line or blown out a cylinder last more then a year. Then there's the headache of charging the batteries, the initial cost, and the maintnece. If you're looking to put the car in compotetion then go dros. If it's a daily, bags. But like Badass said, it's personal preference. My 95 lays frame and has a total of 8 inches of travel, which corisponds to about 5 1/2- 6 inches of usable ride hight fully inflated. I wanted it low. BTW, it's stupid stiff completly full. I keep the bags around 120-140 psi depending on how much wieght is in the car and what kind of driving I'm doing. Either way the car rides about 3 inches off the ground with that much air. That's where I like it. I roll low untill the road gets bad and it's lay'n sparks every 5 feet. My 85 would raise back to stock hieght with that much air and had 12 inches of travle in the rear. The bumper was up to my thigh. I'm 6'1",not exactly a short guy. Different size bags, different style bags, different size mounting cups. They all regulate the amount of lift and drop.
