It's the B5 platform for 96-2001, not the B4. The 99 and 99.5 are not the best years to have, anything before 2000 have a tendency for the control arms to fail. The rubber bushings on the control arm deteriorate, and it's actually easier to change the entire arm. The problem is, there are 4 arms per wheel, so you can see how that can add up. MY2000 and up fixed the problem, for the most part.
Don't worry about coil pack problems. They are fixed under a recall, so it's free. And once they are fixed, they're fixed for good. Not really that big of a problem.
