Finally had time to install my slightly used Bilstein Sports and H&R Sports (29484) on the wife's ZHP. Took me and my 13 yr old about 5 hours. Fought with the rears for a good 3 hours of that. Rear shocks were completely dead (100k miles) and the fronts seem to be "ok". Lowered the front almost 3/4" and the rears maybe 1/8" so far. Hoping they settle a little more. She didn't want to lower it too much, but I wasn't going to replace just the shocks so we compromised on the springs.
Also, replaced my (323ci) VCG since I'm still smelling oil burn at idle after traveling. We'll see, but I think the next step is rear main seal, which I already have. Trying to see if I can find a cheap M52TUB28 since this car seems to be becoming the HPDE car. Before anyone says why? As said above, I've got the 13 year old and he wants the car when he turns 16.
