your m235 is looking sweet!

If your not completely clueless it's fine. yes some speed bumps and dips in the road or driveways you got to slow down or come in at an angle. but for every day driving on normal roads..i haven't had much issues with it to be honest. highly recommend putting some sort of 3m on it.

This might explain why.

Dinan springs on an Xdrive here. Mine sits noticeably lower in the back. I don't like the stance.
I would highly recommend Xdrive vehicles stay away from these springs for this reason.

I'm disappointed with Dinan given the information on their website and the end result produced from their product. Had I known my car would end up sitting higher in the front than the back I certainly wouldn't have purchased their springs.

[AlpsRider]

The Dinan springs were designed primarily to give the car better handling characteristics. If leaving the car stock would have had better handling than with the springs, I wouldn't have lowered it. If I look at the body of my car from the side, even though the front and back wheel wells have slightly different clearances, the under carriage of the car is level with the road instead of being jacked up in the rear as with other setups.

I've updated my earlier post with most of the specs of my setup.

I have Dinan springs on my M235 Xdrive. Like others have said, their is slightly more drop in the rear as compared to the front but personally I like the look. You can see pics here:

Your car looks great. I think the drop transforms the car on many levels.

thank you! Besides the cosmetics, I have noticed reduced body roll as well...not that these cars have much body roll to begin with, but the car does seem more planted with quick turns. This was my first experiencing with dropping a car and with Dinan, and while there are cheaper options out there, I'm very pleased with the quality of their product and the peace of mind that comes with the warranty. My only regret is that the Dinan Shockware tune is not available for the M235!

I'll second that!

I just got done installing the Dinan D100-0927 springs on my M235i xDrive, the drop I measured from stock:
F: -0.4 inches
R: -0.98 inches

Haven't had a chance to get out and drive much yet, but it looks a little low in the rear.

Dinan advertises the D100-0927 springs as a drop of:
F: -0.5
R: -0.625 (5/8)

But it seems I got a full inch drop in the rear, which is what they advertise for the RWD springs ...

Which probably shouldn't be surprising since rear springs would usually be the same for both RWD and AWD applications.

Perhaps I should have known better, but I was hopeful as Dinan listed 2 SKUs for the M235i springs.

D100-0927
Dinan Performance Spring Set for BMW F22 M235i M240i (xDrive Only)
Dinan's Performance Spring Set lowers your car by a half inch in the front and 5/8 in the rear.

D100-0929
Dinan Performance Spring Set for BMW F22 M235i M240i (RWD Only)
Dinan’s Performance Spring Set lowers your car by 1/2 in the front and a full inch in the rear.

I have been daily driving (and auto-crossing) my xDrive car on Dinan springs for a couple months now, very happy with the performance of the springs.

But the rear of my car always looked a little bit too low to me. I contacted Dinan and they set me up with a set of spring spacers which raised the rear of the car 10mm. It's not a huge change, but I am very happy with the stance of the car now.

Thanks a ton for posting this! Never really liked how low the cars looked with Dinan springs, and am going in two weeks to get mine installed. Perfect timing!

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?

It is an optical illusion, and unsure if the suspension geometry is understood. On the Ms the space delta is even larger- and no one questions the M3 M4 M5 credential. Audi R8 has a delta, and, setting relevant, the 2 million LAFERRARI- usually it has more in the rear, but that changes as well. The Koenigsegg also has a pronounced wheel well difference, resolved by the rear wheel and tyre being significantly larger than the front. But it is also a mid engine mount, so the front wheels do not need to absorb that weight like our cars. No one mocks either car for the wheel well difference.

In addition, wheel size makes a difference- a 1/2 life rear tyre has as much as 5mm less than a front- and some can visually see them as smaller. New 225/35/R20 vs 255/30/r20 are 26.2 and 26 rear, or 5 mm difference. 3 months later in a Pirelli life, the rear tyre nears 10 mm difference while the front is still at 809 32nds. Personally I never worn out a front tyre, ended up donating them. You would then beg that the rear space is filled.

In addition, like the Ms, the front has a larger wheel well to compensate for turn-in and absorption. If the front was equal to rear (as it happened to H&R owners, one described a Grand Canyon feel when the front bottomed)- with a turn, you get both bottoming and can get scraping of the wheel well- again relative to wheel diameter. Consequently, the front wheel well being larger is practical engineering.

And yes, with 1-2 people in the car, front lowers a bit.

In the end, adding the 10 extra mm in the rear is a poor decision, as one just raised the rear arbitrarily, thus negating the intended effect and design.

Have you installed these yet? Any pics? I am thinking of ordering them this week.

You can see a couple of pictures with the spacers installed here:

Looks great!! I'm ordering for sure.

Slightly off-topic but: In theory us X-drive owners could get away with replacing OEM rear shocks for stiffer ones and leaving the front struts as-is due to their stiffer construction? ... been wanting to have this question answered for some time now since I'm x-drive with EDC (yeah, talk about limited suspension options ) and i found out Bimmerworld sells Bilstein EDC compatible rear shocks..

Thanks!

I have rwd and rear is tucked.. I will have to check my pns to make sure there wasn't a mix up for springs.

Anyone have the sticker pns for the front and rear springs so I can reference?

Update : Rears are D100-0797a but I'm still not sure if these are correct because there is another recent thread that states Dinan said Rears are D100-0797. Can anyone confirm? My rears are so low..

Update 2: after comparing I think driver rear is good, but passenger rear is lower than it should

[hhl]

I am willing to install the Dinan Springs for my xdrive m235i. and also apex 18 inches wheels with 8.5 et45 front and 9.5 et58 rear. ps4s tires 235 40 r18 and 265 35 r 18.

do you think they will fit with no rubbing problems?

Thanks

Per the Dinan website, Dinan notes the part numbers for the M235 RWD springs as D100-929 and the M235x springs as D100-927.

I believe those are the part numbers for the assembly of 4 springs. The individual springs have their own part number
