Hello! I'm kind of a new BMW guy, got my first about a year ago, a e46 325i. I bought this M5 back in Dec kinda on a whim... Not the best decision for me ever, but it sure can put a smile on my face! She's a 135k mile example, she's been in Oahu since new. I've got a 3'' binder full of every receipt for every purchase on the car. Back in the 90's she got a cat-back Supersprint exhaust and a Dinan suspension. That's why she's about an inch lower. And yes, those are real HRE's. Supposedly there is a Dinan chip in there too, but I've yet to verify it. I've had to rebuild most of the suspension, and do a lot of rinkydink stuff to clean it up. The paint is also shot, I'm going to try to get it re-sprayed before the Euro show and shine in June. I put new plugs in the accessory holes in the lower dash, I had to get a new moonroof switch 'plate'. I've taken pics of most of the stuff that I've done, I should have done a more play-by-play, but here's what i've got!
First up, here she is! (I've since removed the silly fender stickers and the[WTF?] Hamann badges.
I took out the springs+struts to replace all of the bushings...
You should note that the springs in the foreground have been cleaned with a green pad... Don't do that. It took all of the shine off, notice the springs in the background? Also, those rotors didn't look like that, here is a before and after media-blasting, prior to paint:
I was told that I needed to replace all of the shocks because they were leaking, I ended up sending only 1 of the fronts back to Bilstein because it wouldn't rebound. They rebuilt it for $75 +s&h. I highly recommend them, great service.
