High speed vibration and bumpy ride?
Just a quick question that I thought you all might be able to help me with. A couple of months back I had new brakes put on my car and at the same time I had the back of my car raised. I bought the car used and apparently the rear was lower than the front. How or why it got this way is beyond me. Instead of lowering it, I decided to go with the stock set up first and raise it so that it would be even all around. Well, after that was done I noticed that the car now has a lot of steering wheel vibration at speeds of 80 plus. Also, the car does not seem to ride as smooth in the rear as before at any speed (i.e., a little more bumpy per my SOTP 
). Well, I thought that since I changed the ride height, this might be what was causing it. I gave it a couple of months and it has not gone away. Could I need an alignment? I'm figuring the wheels were taken off to do the brakes...could something have been screwed up there that would cause the situation I describe? Anyway, I appreciate your help.

first I would check balance on the tires,you mentioned you did the brakes,were the rotors changed? if so it is imperrative the hub be cleaned of all rust,debris ect... or the rotors won't sit flat,also check torque on the lug nuts,I do mine in increments of first 50ftlbs then 75ftlbsand then final torque of 100ftlbs in a cross pattern,hope this helps,good luck

yes
It could be the aligmnemt. Any time you adjust the suspension you should have the alignment done. Whem you lower the car, Most people will tell you to wait a few days then have an alignment done, the same should occur with raising. Different height= different camber= you neet an alignment to make the car drive properly. The alignment was tuned for the height it WAS, when its changed it will be out of wack for the new ride height.
