Xi Lowering / Have Your Cake & Eat it Too

For the last 6 months I've been working hard at lowering the E46 Xi chassis suspension, through a cumulative effort with different forum members I've accomplished my goal of not only Lowering the Xi chassis but also providing a smooth & compliant ride at the same time. (Having Your Cake & Eating It Too)

The drop will be about 1.25 to 1.75 inches in the front & about 1.25 to 1.5 inches in the rear, this drop will "Even Up" your current look because as you know the front sits Higher than the rear. All in all this will make your Xi chassis E46 look Great while still maintaining its AWD capability with ease. Some of the best points about this suspension system are:

1) You'll still have a nice factory OE ride with planted handling that's very smooth feeling.
2) The price is Very affordable at roughly ~$799.
3) The Front & Rear shocks are BOTH Externally Adjustable, meaning you can make strut or shock adjustments in seconds by twisting a knob.

The four major components to making this Xi Lowering a reality are:

1) Koni Sports Front Xi Struts (Externally Top Adjustable)
2) Rob43 Special 9 Way Externally Bottom Adjustable Rear Shocks, these special shocks are not only a bigger diameter (they fit perfectly) than any other E46 shock, but they're priced right too.
3) RWD* Lowering Springs
4) Supreme Power Drop Hats

This suspension can also be easily fitted to an Xi Touring (It was tested on one also), but the price goes up ~$ because H&R Sport "Xi Touring" Springs are needed due to the increased rear weight of the touring model.

If you'd like one of these Xi Lowering suspensions for yourself, shoot me a PM & we'll discuss it.



Rob43






* It's NOT well known, but certain RWD suspension parts fit the Xi chassis perfectly; Choosing the "Correct" RWD Springs are one of those items. Only one or two RWD springs can actually lower the Xi chassis the way you'd want.

I wish I had known about this before I dropped $400+ on new front springs and used rears. Too late now.

There are components of my Xi lowering suspension that would benefit your current ride, that could be front or rear dampers or maybe front drop hats & spring pads to help with how it sits/looks.

OK.

You want the Supreme Power $89 dollar Drop Hats, shipping included.

http://www.supremepower.com/57573/68...perch-bmw.html

"IF" you're Completely happy with your current ride, keep your rear Koni's. But if you perceive Any bounce/bounciness that you'd like to dial out, then my 9 way rear shocks are the ticket.

I bought the Eibach Xi-specific lowering springs. I couldn't be happier. 6 months, 5000 miles, zero issues. I don't see any reason to go with anything other than that since the Eibach is tailored to the Xi chassis. Just my opinion.

What's the price of that kit and does it level the car and how much drop? I'm only looking for about an inch or so as I have a lot of snowfall in my area.

That's good, I'm glad you're happy with the Eibach Xi springs because they are a fantastic choice. The problem with just buying springs is, you don't have all the other components that make an overall suspension package.

What I'm recommending is an actual "Package" that will transform the Ride & Look of the Xi chassis. Having the ability to instantly change strut & shock settings is a Huge plus for anyone that wants to obtain the ultimate ride & handling for their driving style and road conditions. Springs alone, or when matched to standard dampers can never achieve this.

Last, as almost everyone knows with an Xi, your front end is almost always sitting Higher than the rear; My Suspension System Fixes This.

I just ordered the supreme power drop hats. I'll post results when they come in so people can see what H&R springs paired with the drop hats look like.

That sounds great., I know you'll happy with your results.

When taking pics of the side of your Bimmer, try to frame the entire chassis as close as you can in the pic with the lens about 2 feet off the ground. If you need to make any adjustments to obtain front to rear "Perfection", I know how you can achieve that too.

I love the setup. In general I've always liked a sportier ride so I think the ride is firm without being too harsh. It's perfect for me.

Here is a pic from a few months ago. I'll be getting the drop hats early next week so I'll install them at some point next week.

Has something recently changed ? When we last talked, you didn't even want to spend $500 on your Xi's suspension.

I just looked at your pic & your Bimmer looks good. The drop hats will lower the front about 1/2" more but in turn will "Lift" the rear end slightly more so be prepared to install thinner rear spring pads to even things out.
