Got the Koni sport springs, need more drop

I got the Koni sport springs from Nick for my 99 9-3 convertible, but I need at least another inch of drop. The problem is the rear more than the front. The rear still has a pretty big gap. Is there any way to get additional drop in the rear? I can't cut the springs because of the way they are wound to a smaller diameter on both ends to wrap around the bump stops.

Thanks

How long have you had the Koni springs on? It may take a while for them to settle lower. The front will always settle lower faster than the rear.

the koni springs offer a nice drop. you just need to put approx. 2.6 dead whores in your trunk.

I think what he is trying to say is load-up the rear for a while to help the settling process. It should look even when done.

yes.


but, on the serious, wait for them to settle. i have a few friends running these springs and their cars all sit pretty level. those are 5 doors though, don't know if a vert would sit differently.

Well I loaded 5 cases of tiles in the rear trunk, about 200lbs. I hope that will make it settle a bit.

Definitely give it some time.

My 9000 gradually evened out over a couple months (and miles) after I installed H&Rs in it. Same thing really...springs are springs.

Here is how it sits now, just as a point of reference, but it's hard to see the rear it looks lower in the pic than it is:

Yeah, that's too bad you can't cut a bit off of them

That would have been my recommendation.

Thinking of doing this but wanted to hear from other convertible owners. How is the ride?

What do you have for other suspension mods (6 point brace, rear sway, etc)

Just the rear ARB for the time being. Steering brake and front ARB bushings on their way though. Plan on doing the 6 point sometime in the future. Ride is pretty good, but time will tell when the suspension settles a little more.

OK, car is still not low enough. And is it just me or do the 17's look kind of small? Stock BMW's look lowered compared to my car!!

That is widely regarded as a horrible idea.


If anyone does this, I will mock them mercilessly, then call them a stupid ricer.




When you heat springs, you change the properties of the metal, and that affects how the springs work.

Cutting 1/2 coil off is a much better way to lower the car.

Problem is that in the rear the springs taper to sit around the bump stops, so I can't cut. Otherwise I would have done it long ago.

A huge reason your not seeing the rear drop more than you want it to since its settled is there isn't much room for the rear suspension to travel. Its due to the design of the car. Thats why its probably gonna sit where its leveled out because the Koni engineer's have taken that into account so that your not constantly slamming the rear axle into the bump stops.

You sooooooo don't want to drop the car by more than 1.5 inches or so.

You'll start to have all sorts of camber issues and will start bottoming out on potholes. You'll end up hurting performance instead of helping it.

The max depth of drop is based on a couple of factors, the least of which is how the car looks.
