You can easily find suspension for your car just like any other parts for this car. I went with Koni Yellows and H&R sport springs and am very happy with my setup. The ride is awesome. A bit stiff but handles sooo well.

I think it is great that Rob offers some solutions for people who don't want to get too stiff, but I just upgraded to all poly (superpro subframe and upper spring pads, powerflex inner upper and lower control arms bushings in the rear [went with new powerflex rear LCAs that include the inner bushing], UUC RTABs, powerflex FCABs, and powerflex sway bar bushings front and rear). I have H&Rs and also had to get new rear shocks (one of the old xi Bilsteins was totally blown), so now I have the e36 M3 Bilsteins. I still don't think the car rides badly, and we have some rough roads... It is very stiff, but still reasonably compliant by my standards... When going across small "sharp" bumps is really seems like you hear the thuds much more that you feel the jolts. Might not be a setup everyone wants, but I find it odd that some people who have tried a single poly item, say RTABs, switch back due to the harshness... They must not know what they are getting into when they get poly because I can't imagine that one change would be all that dramatic.

I plan to make a thread about my changes, at some point, but I thought I would go ahead and share with you guys.

I have poly RTABs and while the car is kind of stiff it's not bad at all in my opinion.

Same here, as well as poly FCABs, differential bushings, and rear sway bar bushings. No noticeable increase in NVH over stock, just sharper control. Planning to solid mount my subframe as well once I reinforce the floor.

As far as my suspension goes. Iíll be installing it within the next week or two hopefully!

^I wonder how much difference one could notice between the solid subframe mounts and poly? The Superpro kit looked good and gets rid of the empty space the stock rubber mounts leave (Powerflex mounts were quite a bit higher; they also sell inserts to use stock rubber bushings and fill the space with poly, but I did not like that idea). I think it's a good (albeit expensive, if you can't do it yourself!) upgrade.

ECS did have a sale on Powerflex... might still be going on. I figured since I don't do such things myself, and labor is a bear, I might as well do it once and do it right. I am glad I am happy with the result. It's still more comfortable than the old Prelude was with similar upgrades and all poly. Now I can out corner M cars and get beat down the straights by a Camry, lol...

Best wishes to all.

(Having Your Cake & Eating It Too)

The drop will be about 1.00 to 2.00 inches in the front (Depending on Spring Choice) & about 0.25 to 0.75 inches in the rear, this drop will "Even Up" your current look because as you know the front sits Much 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) Sport Front Xi Struts.
2) Rob43 Special 9 Way External 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 chassis, it was tested on several with excellent results.

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

##############################################



****** UPDATE: For those of you on a tight budget, I've tested a Non-Adjustable option that gives a nice looking drop that "Evens" things up and rides like Stock OE for comfort. Price shipped is roughly ~$549 for this option !!!



* 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.

** Depending on options these might NOT be needed, this could save you ~$90 dollars.

Rob,

Are you still selling these setups for a XI wagon? Tried to send you a message but your box is full.

Thanks

An assumption... as nobody can validate the suspension and information, so people could repeat the results.

You have to take their word for it absent that information. Saying I achieved this or that, but can't tell you how I did it is counter-intuitive! Never seen anything like it on "any" car forums I've been on. Information is always shared freely and willingly.

Anyways...

Hello everybody! 4 month past after xi suspension has been rebuild and lowering kit installed ( I have front set bilstiene performance b6 with eibach pro kit springs). Looks grate(as soon as possible wanna install drop hats), grate steering as well, BUT when I driving on freeway over the bumps, I hear and feel very hard hit (when struts hits the upper spring hats). Bump stops have been removed. Is this happen because springs too soft ?

Also, not long ago in this forum I wrote that I was trying to install m3 e46 front shocks. For these who wanna try or think to install e46 m3 oem front strut assembly - IT DOESN'T FIT for xi. I just wasted money and time. Lol

You needed to shorten the bump stop a little bit prob an inch. For others reading this don't remove your bump stops it's stupid and unsafe to do.

I cutted bump stop an about 1.2 inch, but then I red in some other russian forum that it's stupid do not remove the bumps and that's why it's happen. Anyway I realised that it's not right and I going to install it back and just drive carefully.
