Dinan rear springs too low
I just installed my Dinan springs with ride control on my xdrive. Front looks to be dropped exactly what I was expecting but the rear is slightly lower that I thought, actually putting the top of fender 1/4" lower to the ground than the front. Do the fronts tend to settle more and everything will balance out? I also had new OEM struts changed only a couple weeks ago from a warranty repair, maybe they haven't settled yet either? Has anyone experienced this with Dinan on the xdrives? Has anyone ran Dinan springs on front and MP springs or eibach rear?

My rear was a lot lower than the front when I had them.

I changed to coilovers because I needed height adjustability. It didn't really bother me that much though when I did have them, but I would've preferred the heights to match.

Dinan is 1/2" front, 1" rear, as stated on their website. It should be sitting perfectly... Any pics?
Here's mine for reference, only RWD:

Here's mine. 2016 M235i, with BBS CI-R wheels (same as Dinan) and Michelin Pilot 4S tires sized 235/35/19 ET45 (8") front (yields zero scrub radius), 265/30/19 ET48 (9") rear. The Dinan springs in the front have a 1/2" drop which are 10% stiffer and yielded a 1 degree negative camber during alignment. The rear springs with 1" drop are 30% stiffer. I think the height is perfect for handling although huge dipping bumps at high speed will not be absorbed as much as stock. The car does look a bit slammed at the rear but the body is level. The setup has much less understeer now and to me feels just about right for normal driving.
I used the site listed below to do my fitment calculations. My car's spec info is already plugged in.

the X-drive model springs on dinan's are not soposed to be as low as the RWD models. That being said when i installed mine - i noticed the same thing as you. Me personally I love it.. yes i would like the front of mine to be just slightly bit lower in the front but i like the stance. I also added 15mm Spacers all around on my car as well. I have some pics to show. The pictures of the Tires/drop are my winter tires im running.. Sadly i half to winter drive this car( not really sad this car is a blast in the snow lol) Tires are 225/45/R18 all around and yes they rub slightly..Going to try and remove the spacers for the winter tires, hopefully that will help the slight rubbing during the winter months. Any more questions feel free to ask.

I'm running Michelin Pilot Sport 4S which is only available in 19" in most markets, the MPSS are excellent tires but when compared to the 4s new version, they are too soft for hot climates. They also suffered from roll over no matter how much air I put in them. The new 4s has stiffer sidewalls and appears to be wearing MUCH better than the stock MPSS, it's possible that the drop in height has improved the negative camber which was at about -1 degree after installing the Dinan springs and could be giving the outside edge a bit of a break.
I looked at buying your wheels too, they're really cool. It looks like we have the same taste in cars. |

I am not sure why Dinan does it but that rear does look slammed on some of the pictures, as if the suspension is almost fully compressed in the rear and hardly has any travel at all. I understand it may work when aesthetics are more important than function. I am not sure why the changes to the handling of the car that brings should be considered improvements. It was supposed to be a fun to drive car. Yes, it would make the car feel more planted. At the same time, when near its limits the car would no doubt have more understeer. On a practical side, what happens if you put 2 people in the back and/or some stuff in the trunk? How about the rear shocks and wheels longevity? Just saying...

I think your wheels have a higher offset all the way around, but they are cool looking wheels. The BBS/Dinan wheels were the only ones I could find with the perfect offset besides custom order. I didn't want to run spacers. |

Yep, the Dinans definitely look too low in the back for my liking. It would look a lot better with another 1/2" gap back there and at least another 1/4" in the front.

I suppose it depends on what wheel/tire height you have, my car which has a stock front bumper drags the black lip under the bumper often when leaving gas stations with a dip. The bumper also will catch parking lot concrete blocks. That is why I haven't added a lip to the front yet. Your mileage may vary...

Ideally I would prefer that as well, but I think Dinan made the drop that way for a reason because it handles great with decreased understeer.
