I just installed them in my '89 civilian sedan, I installed them with DNA shock absorbers and DNA head gear and that's it. To be honest I thought it would suck for the price to drive, but I'm actually very impressed with the ride quality. The only downside I've found with them is the o-rings that come with them. They are enough to put an o-ring on the shock, so I had to buy more o-rings from my local auto zone to keep the bushings nice and tight on the shock absorber. Shock, except I can't say anything bad about her. I highly recommend them if you're like me and can't afford to spend $1,000 on coilovers.
