Duh. You weld the lead weight on.

Or at least use reflective racer's tape.

Do you mean you think there is not a problem with your install based on the conversation with Eibach? I guess I might as well give them a call tomorrow because I'm a bit confused on my drop too. I know it's only supposed to be about a .5" drop in the rear but I think I got more like nothing at all to maybe .2". It's been 6 days and about 30 miles which should be enough to allow settling to occur for the most part. And frankly I don't see how these springs even could lower the car. They're the same length (within a couple of millimeters) and same spring rate (OEM is 460, Eibach is 456). That would seem to translate to an extremely minimal drop which is what I got. The front looks good but the rear is pissing me off...

The thing that really confuses me is that H&R sports are rated as a 1.2" drop in the rear, Eibachs are 1.0" (both measurements based on non-sport suspension) so there should only be a .2" difference between the two. I had H&R sports on before this and there's at least a .6-.7" difference between the Eibachs and the H&Rs.

LOL, maybe I'll just keep all my OEM parts in the trunk - that'll make the rear look better!

Depending on the temperature it may reinforce the steel actually but shorten its flexibility. Without proper thermo analysis by an engineer the procedure is useless.
But would you even go for that set of troubles to lower it 0.25-0.4" ?? Stop looking at these gaps get in and drive, when you are inside you dont know what the gap is and nobody cares about it from outside. Handling and comfort is more important than the 1 min look from outside.

I'd say that's good advice except that I care both how it looks and how it feels, and right now it doesn't look good having mismatched gaps. And I don't know if it's all in my head but I could swear I notice that the rear feels too high when I'm in the car. I feel a little pitched forward in the seat - like the back is lifted up. I'm not sure if a .5-.7" difference is enough to feel this but I think it might be.

I agree comfort is more important than the gap, otherwise I'd have just gone with H&R sports again. And the really annoying thing is feeling like I wasted time and money to install lowering springs that didn't lower the car. Looking through the 19"s on OEM sport suspension thread the rear of my car looks the same or higher.

LOL. I was wondering when the FOAD post would come.

Don't be afraid of my über intelligent posts. Just because you can't comprehend them, doesn't mean the REST of the community can't either.

And even someone like YOU should comprehend the humor behind me making fun of someone trying to GHETTO mod a BMW 3 series by heating up the springs to let it sag. It's like taking the Mona Lisa and painting a set of bigger boobs over her because, well, she's a little bit saggy in the picture.

Adjust the seat tilt? It must be in your head

Ha, yeah my seat is tilted all the way down in back, up in front already. Actually it occurred to me I know it's not in my head: when I first installed my coilovers the front was a nice flush drop but I'd set the back about .6-.7" too high. As soon as I got in the car it was very noticeable that the car felt slanted. I adjust the rear perches down about .5" and it felt fine. So yes, even a .5" difference can easily be noticed.

I don't get why my Eibach springs aren't an even drop like all the other cars I see posted. Guess I'll be ghetto and cut half a coil because it doesn't look or feel right.

why dont you get some B&G springs, I was deciding between the Pro and B&G and went wit the B&G for the lower drop...The ride is pretty smooth..I believe the drop for the sedan is lower.

That looks pretty good on your E92. According to the EAS site, the B&Gs lower 1.6" front and 1.4" rear (same for all E9Xs) which is more of a drop than the H&R sports. I think that'd be a bit too aggressive for the Koni FSDs to handle and actually the H&Rs were already a little lower than I wanted. I like where my fronts are now, just the rear didn't drop like it should have for whatever reason so it needs to come down .5" and I'll be happy.
