I too was worried for the same reasons. The problem is you read too many stories from people being negative. They are easy to install, for a coilover. I mean there is some work to get them on but its a car, its supposed to take a little work. I have the same spring rates and my car is 100% better after install. They are awesome. Have funI know a lot of people have been posting about bc coilovers but I'm 70/30 on them right now. Ordered mine a couple days ago but it will take a couple weeks to get the 9k/12k springs in and assemble the coil overs so they're gona call me when they're ready so I can pay for them. I hear so many mixed stories about the installs and it makes them sound like an absolute nightmare...anyone have any input that might help make me feel better about spending $1300 for coilovers and strut bushings only to have loads of problems with them? Helped greatly appreciated!
