Thank you jasonbimmer for putting the correct picture of how the ride height is measured into this thread!! I was going to do the same. I can not understand why some of the guys on the forum just want to point to "look it up in the archives" and be "smart about it" instead of just answering the question? We are all BMW enthusiasts here, some with more knowledge than others, and we should all be happy to share our knowledge and experiences with others. None of us know it all, and we can all learn something. If you don't learn something new each and every day, you may as well crawl into the pine box.

I'll be keeping an eye on this thread. I may be picking up an XI for my wife, but the ride height is something I would change if I got one.

It's a fairly big difference. I wish I took a picture when I had a ZHP and my parents had a 330xi. I would estimate it to be 1-1.5" higher.

All 2002+ rwd 330s will be as low as the ZHP since all 2002+ rwd 330s got sport suspension.

Question drop hat/pad update

Standard XI Suspension vs Standard I Suspension Height:
23.85in vs 23.19in (Front) = .67 inches difference
22.52in vs 21.85mm (Rear) = .67 inches difference

Custom Stock XI Suspension vs Standard I Suspension Height (Projected):
23.26 vs 23.19in = .1 inch difference
21.93 vs 21.85in = .1 inch difference

so there you have it. it is going to be as close to I specs as possible without having to shell out a whole lot of money (aside from the stock parts)
Any word on the drop hats and spring pad install? Success?

Has anyone had the opportunity to test this set-up out?

Thanks for the reply. I will be on this project asap.

I'm looking to buy some 18"x8.5" Sportline CSL replicas from Modbargins and some 245/40/ZR18 Pirelli's that will definitely benefit from the subtle but effective .5" drop.

All I need is the mask and fire-arm and off to the bank!

Sub'd. Kaboom great job with this! I've been wanting to have I ride height on my XI but was afraid of ride discomfort over bumps.

How is the ride Kaboom? Is it harsh in any way?

going to be hard posting before pics. I have after pics now tht I just did an alignment. looks better. ill post pics when i get home. rides exactly like stock. Remember, I'm not tweaking the stock suspension, I'm simply seating the spring into a deeper pocket. As a result, I dropped 15mm.

This is great because these lowering perches can be used with eibach springs and the drop will be as low as H&R yet the ride remains descrete.

@e46alfonso

Your suggestion was exactly what I've been looking for before I purchased suspension parts for my 2002 325xi (100,000 miles). I thought all along I'd go with H&R because of the slightly more aggressive stance than Eibach. But the "descrete" ride, as you put it, is just too attractive for daily driver. So I'm now tracking the following shipped items:

- lowering perches from supremepowerparts.com (item SUFT015) $70.00 shipped
- 5mm rear upper spring pads from TheBMWPartStore.com 2 x $5.23
- Eibach Pro-Kit Springs from advanceautoparts.com $240 shipped (were 20% off + $50 coupon towards next purchase)
- 3-series Strut/Shock Mount Kit - E46 325Xi/330Xi from turnermotorsport.com

Now I'm saving up for the right shocks/struts to go on sale. With the added drop from the perches and 5mm spring pads, I'm wondering if I could get away with Bilstein Sports. Kubica recommends only using them with H&R. But with this setup it'll be just as low.

This is my favorite car I've owned. It's now paid off and I want to drive it for another 100,000 miles on this suspension!

You can use the Bilsteins on whatever you want. The shocks/struts don't control the ride height, the springs do. There are many people with Eibach/Bilstein combos but there have been reports of leaky rear shocks with Bilsteins, just FYI.

Also, I would save the $70 you plan on spending on those perches and just stick with the OEM ones on your car already.

Make sure you change out the upper shock/strut mounts, all the hardware to mount these things (especially the lower pinch bolt), and the rubber spring pads on the front springs. All of those things are a much better use of your $70.

I recommend Bilstein e36 M3 rear shocks, not rear Bilstein xi shocks.

I would get OEM rear shock mounts plus the z3 reinforcement plates.

I don't have experience with the front perches since I use camber plates.

I agree, but I think if you used Bilstein Sports with OEM springs it would drop it a bit up front. Definitely not recommended however- that's not how you setup a suspension.

I think the drop-hats work in the same manner -effectively reducing the height of the strut piston.

I just got off the phone with a guy at SupremePower and he explained that the drop hats change the position the spring sits on the perch. They don't effect the height of the strut piston at all. Can anyone confirm/verify this? Though I'm willing to be a guinea pig with adding the drop hats and 5mm spring pads to a Eibach with Koni/Bilstein suspension (the goal being H&R height with street quality ride), I'd choose to keep OEM perches, as SamDoe1 suggested, if it meant avoiding premature wear on my struts. Thanks!

@kaboo0m

Did you install these yourself? If so, can you confirm that these drop hats/spring perches do not in fact effect the height of the strut piston? Thanks.
