I'm at college, away from my garage, so I had a shop install everything for $150 bucks.. From watching, the caster/camber plates are probably the biggest hassle, getting up there after disconnecting the brake caliper to align for the 4th hole to be drilled.. otherwise it didn't look bad. You will need some bearing grease to get the upper perch on the coilover kit ready.. On rough estimate, after carrying my old bullitt kit, I'd say it dropped at least 30 pounds off the front end.
You are going to love it.. I'd highly recommend the 350lbs. spring with whatever bilstein strut you end up with (HD, 03 Cobra, or Cobra R valved). Its not too rough, but there is very low body roll.
I'm at school in LA now but a great shop I trust in the Bay is Apex Motorsports in Santa Clara. They are Griggs and Maximum Motorsports dealers, and do quality work.
