BTW, I had the stock 225m wheels and pirelli p zeroes weighed.

The back wheels weigh 54lbs each with the tire mounted, while the fronts weigh 52lbs each.

Useful info for knowing how much unsprung weight we can save with new wheels.

Fedie, glad I finally found some photos of the H&R springs on a xdrive35i. Just ordered a Lemans Blue/Coral xdrive35i and would like to lower it without going too crazy with cost or drop as with coilovers. From what I have heard, it isn't too hard to get the alignment back into spec with just the H&R springs. Did you run into any alignment issues? Too much negative camber that couldn't be corrected?

FYI, not my first rodeo on suspensions. I'm trying to do something without going all out for once and running way too much negative camber for street purposes. I've got some highly modified M3's to serve the purpose of suspension performance.

Are you just trying to eliminate wheel gap or do you care about handling characteristics? I was under the impression that the H&R springs were designed for the lighter 28i, so not sure how that will impact handling. I could be wrong though, can someone enlighten me? I know KW has a V1 kit that you can get pretty cheap from vendors that is designed for the 35i, but it will be more expensive than the H&R. Probably ride better though.

para....honestly, I want to eliminate the wheel gap. Yes, I care about the handling characteristics but I don't think I care to make a huge change to the feel of the M-sport setup the car already has. I'm not racing this thing. I don't need it to beat me to death on the road. I have had all sorts of coilover setups over the past 10 years and I have found that most coilover setups really ride quite stiff on the street even though they handle great on smooth roads. The only way to ensure good performance from these systems on rough pavement is to pony up the big bucks (like I did with AST's on 3 of my cars). The difference is so noticeable that I'm really afraid of buying an off the shelf coilover kit again. I'm scared the KW's are going to be too rough riding for me on the street. I wish I knew for sure because my preference would be to do the coilovers with camber plates and whatever needed to adjust the rear.

I'm leasing this thing, and I really don't want to over complicate things. I know that the H&Rs will lower it about an inch, ride somewhat stiffer but not much, give up some performance over a coilover setup, but likely more livable for a daily driver on the rough roads here in Oklahoma. I'd love for someone to tell me otherwise

The KW stuff rides softer than the m sport stock stuff. I have ACS on mine and the frost heaved roads here in Calgary can be a bit painful. For the most part I'm happy with the ride quality, drop and look of the pain old spring kit. I may look for a shock set as the rear tends to be easy to bottom out on the really bad sections of road.

Shocks are not high on my list of things to do. My next mission is M3 brakes all around

Twix, thanks for the input. It puts me right back on the fence of what I should do, again. LOL. So have you been in an X1 with the KW, m-sport, and your ACS? Sounds like you would rate the ride stiffness as ACS>M-sport>KW. If you had to do it all over and price was not a concern, what would you choose? Then if KW, V1 or V3?

Having gone from M-Sport to KW V1's on mine, I would definitely rate the KW's as a better option for ride quality.....they just seemed to be far less harsh and crashy than the stock M-Sport setup.

Great feedback! That makes the decision much easier. I should just do the coilovers as I'm not as concerned about cost. Plus, I can install those without much headache. Easy swap!!

There's no point on getting the adjustable valving with the V3. If you're not taking then the V1 will be perfectly tuned, maybe a bit on the mushy side. If I could do it over again, I'd do my ACS springs with an adjustable shock to soften the rear up a bit.

What are you guys running coilovers using for camber plates and additional rear geometry adjustment?

I believe it's front camber plates and rear adjustable control arms

As far as the ride, I must say I love it. Is tight but drive able and the wheel gap is great although coil overs do a much better job at that.

Alignment, easy as a pie

I like the factory rims better than the gray rims.

I do like the look of it lowered but for everyday usability, I'd probably only drop it 1.5" from factory and then use spacers. Then when the tires are up for replacement, I'd get slightly wider tire specs and remove the spacers

I also agree with the prior comments that the X1 is the way to go if you want the turbo 6 vs 4-cyclinder turbo if you want a BMW small wagon in the states. It's too bad that BMW doesn't offer 5 series wagon.

By the way, I wish the X1 '35 came with factory exhaust outlets on each side (like 3/4 series) instead of one side.

Does it make it harsh, I don't mind a firm ride but I don't like it to be jarring over bumps. If that makes sense.

Resurrecting an old thread since it fit's the subject:

Just picked up my X1 xDrive35i M-Sport (19,200 miles) from my local shop, had them install the H&R Sport Springs that I picked up from Turner on their Black Friday sale. Got to drive the car home 20 miles in the pouring rain thru city streets and here is my first impression: Excellent!!

1) Brings the car down about 1" all the way around, car looks so much better, i.e. it looks like a car and not a pseudo-SUV on stilts.

2) Believe it or not, but the ride is not nearly as harsh as before. I could immediately tell a difference: while the ride is still stiff, the harshness of potholes, expansion joints and other road imperfections is much reduced. Don't get me wrong, you still feel them, it's just smoother than the stock M-Sport springs. The car now rides very similar to my previous E90 328i M-Sport.

Due to the weather conditions couldn't really take it on a spirited run down some back roads, but so far, so good. I'm very pleased with this mod so far.
