Im looking to buy new front and rear suspension components today. I picked up a 93 M5 about 2 weeks ago with 180k on the clock. Suspension is tired. I was looking at some kits that FCP offers, but wanted to see how many of you recommend the sealed spherical bearing control arms before I buy standard HD stuff. Concerning the rear, I hear that the rear subframe bushings are usually worn by this mileage, and the diff mount. Anything else in the rear I should buy?
