I found this shocking and maybe it's been shared previously but it's worth noting again. On 435xi the dinan drop is interesting. The front went from 27.5 inches to 27 or maybe a 1/16th of an inch lower. On the rear it went from 27 5/8 to 26 or 26 1/4.

Huge drop in the rear. Not so much in the front. Truth be told the rear looks perfect. No ghetto look at all. The front still looks too high. I am not gonna switch it out but it is what it is.

As far as ride quality or improvement. I really don't notice anything. However i haven't driven it hard yet as it's been raining. It might be slightly firmer. But man it's ever so slight. I thought the suspension quality in stock form was pretty darn perfect between comfort and sport. So this very little firming up is actually fine to me.

Anyways. Net net. Happy with the ride quality. The stance has a backward rake. Ehh. Not really my thing. Sorta reminds me of a mustang now.

Did you retain the OEM shocks with Dinan springs?

[matty088]

Yes ^

[cfm56d7b]

It's very difficult to control suspension height with springs only. That's why coilovers are preferred if much more precise suspension height setting plus adjustable dampen / rebound behavior are needed.

Shouldn't be a surprise - iX factory stance has front higher than rear (at least on both of the AWD I've owned)

Dinan reports 3/4" drop front/1" drop rear = same front high stance as OEM, just lower all around

Additionally, Dinan lowers the 435i/440i by a 3/4" in the front and a full inch in the rear for improved suspension geometry and an even more aggressive stance.

Did you also install the Dinan Ride Quality & Handling Kit? Big red disclaimer on their site that these need to also be installed to achieve advertised ride height/handling/quality

NOTICE: Dinan Performance Spring sets should be purchased and installed with the corresponding Ride Quality and Handling Kit to achieve the advertised ride height, performance, and ride quality. While not explicitly required, if the matching component is not purchased and installed you will get less than favorable results in the form of poor ride quality and improper handling traits. While we will maintain a full warranty on product defects, any claims against the car’s improper handling/ride quality traits due to not purchasing the corresponding handling kit will not be warranted.

Car should settle a bit after driving, but front high stance will still be there...

[matty088]

Yea got the bump stops

[Ultimateone]

Post some pictures please, also after a week they will settle a bit. I'm trying to decide what route to go with my suspension also.

I did a drop on a 435i not xi and the drop looks pretty even, but I've seen others in the forum have the same problem as yours with the "xi" (xDrive) having a reverse rake look due to the way the front suspension is designed.

[matty088]

Definitely a hard core rake. Its not awful looking but would be better

Not too sure I buy the suspension settling in aspect. I will see. And follow up

Will snap a pic too

[matty088]

And btw. These are still a no brainer over h and r. H and r looked slammed. Definitely not my cup of tea.

The xdrive have a reverse rake with Dinan springs. Same thing on mine. You'll get used to it. Never really changes after it settles as I still see the reverse rake after a year with it.

Surprised you didn't notice any improvement to ride quality. I immediately noticed the reduction in body roll on turns. But like others have said, you should consider replacing the dampers or if you have EDC, get shockware as the stock ones is bouncy

[matty088]

yeah i take it back. finally got to drive the car. Holy cow what an improvement. I am shocked how the car handles. so tight. no roll. pretty incredible actually.

and i say this comparing it to my weekend car which is 2650lbs with very high end coilovers and just about everything else tightened up/bigger.
it was really that good this morning coming down the merritt (ct/ny) at 6am. looking forward to way home.

ill get some pics.

[GA/\/\/\/\A_CT]

Matty, are you in Fairfield County? If so, can you tell me who did the install and how you rate the experience?

[matty088]

I am in ffld county. Springs can be done in your garage with a diy. Trust me. You want to do this yourself. No one is gonna take the time to torque everything to spec. They are gonna hit it with an impact. Ugh.

[Ultimateone]

Don't forget the pics chief, also you should update your profile to 435 instead of 335

Sorry. Leave early. Get home late. It's dark.

[rixride]

FWIW I also had the Dinan springs and bump stops on my f32 435 xdrive. Was not satisfied with the stance or ride and went with KW V1's.
I don't track the car but wanted the front to be lower then the rear which I was able to accomplish.
The stance is perfect and the ride quality is second to none.
Please excuse the iPhone pics.

Unfortunately, some shops do cut corners and use impact wrenches instead of properly tightening all bolts to proper torque specifications. Interview the shop owner. Reputable shops will be happy to answer all questions.

I did it myself but the problem I ran across was no one had accurate torque specs online. Different post had different torque specs and some stated that I needed to replace one of the bolts altogether.
