I've had my civic since I was 17. I always test drive new cars, and love them, but when I get back in my civic, it feels like home. So, I think I've finally decided to ditch the new car idea and dump lots of cash into my baby. What I need to know is if I can do a rear disc conversion on a DX. I've seen the kits for EX models, but I'm not sure how they're different. Also, any other information on what I should add/improve to get everything up to par (engine comes later) would be appreciated. Right now I'm just looking to get it handling better, overall.

Also, it has a tendancy to vibrate a bit more around 85-90mph. I'm somewhat worried that this might not go away with suspension work, but I'm not exactly sure what it is. ideas?

thanks
