hey guys, has anyone tried using the Dinan Supplemental Ride Quality & Handling Kit with any springs other than the dinan ones?

Are you trying to upgrade from what is in the kit?

Yes, I use these OEM bump stops with Eibach Pro-Kit Spring. These made a big difference. It's one of those things you simply must have if you only use lowering springs.

How are the pro Kits springs working with the Adaptive suspension on your M235? Eibach doesn't seem to make a separate spring for that suspension like H&R does.

I like them. Overall, it's a good upgrade if done along with the bump stops. I like the lowering both visually and functionally. It's already just past the reasonable for the stock shock absorbers so I definitely wouldn't want it to be any lower. Someone here posted a picture where they produced an excessive front rake as the rears didn't settle - not in my case. The lowering is 15 mm front and 10 mm rear when new, although after 12k miles on them I think the rear settled a bit more (or maybe it's just that I put on 255/35/18 tires in the rear that seem to fill up the wheel well more). With the bump stops in question they handle really well, improved turn-in and cornering, much improved stability of the car at high speed, less nose dive and squat on braking and acceleration, a bit tighter steering wheel (just right). No issues on good quality roads.

There may be issues on cr*ppy roads with lots of potholes and waves on them, especially if the car is loaded - more chance of bottoming out, damaging wheels, etc., or even hitting the underside if you go too fast for the conditions because the springs are still not stiff enough (I'm not sure they are stiffer than stock springs), and the shocks are not stiff enough, to prevent too much vertical movement.

I cannot imagine how I would drive with the kind of lowering you get with H&R. That would be for the looks only. I really think that is wrong for the stock shocks. The reason I chose Eibach over H&Rs is precisely because they do not produce too much lowering.

Adaptive shocks longevity? That I don't know. Sometimes I drive on really bad roads so that could be a factor. Right now I am at 12k miles on them and want to go to the dealer and check everything in the suspension including shocks. It's really cold (- 20 C) out here and once it got cold I started hearing a knocking/rattling sound in the suspension in the morning, can't quite place it, that would pretty much go away after about 5-10 min of driving, could be the shocks dying or, hopefully, just too cold outside and something plasticky/rubbery getting too stiff and rattling about. Will find out soon.

Thanks for the detailed response.I'm looking for an alternative to the Dinan spring kit because of the very expensive installation cost. I've already ruled out the H&R's because of what you said about them.I put some Eibach's on a Taurus SHO and was very satisfied with them so I know they make a good product.
BTW Our temps here are about the same as you are experiencing and I was just thinking that all squeaks ,rattles,and groans have to be ignored because cars really don't like to be driven in this type of weather!

The Dinan springs should cost you no more to install than any other springs.

At a Dinan dealer they do. BMW book rates.Close to $1000.

Then just don't have them installed by a Dinan dealer. I had mine installed at a speed shop including the new bump stops and spacers for $225.
If you go with another brand like H&R will you have them installed by an "H&R dealer?"
Happy with my Dinans but there is no way that I was going to pay $1000 for a simple spring install.

Exactly my thoughts... dinan will still stand by their product no matter who installs them, as long as they are installed properly.

Very satisfied with mind too, I just DIYed

[Tpeterson]

Thanks for the feedback and advice. I had thought of non Dinan dealer installation also -DIY is more than I want to attempt- but wondered about warranty coverage. You're both right.They have to honor their warranty if the springs are installed correctly. It's been mentioned already in this forum,but I'm glad to hear someone has done this way.Something for me to think about this Spring!

Go with the Dinan and an indy shop install Tpeterson, and also save yourself some additional $ by just ordering the bumpstops Dinan uses for their "Supplemental Ride Quality and Handling Kit."

Rears are part #: 33536762722

Are these the bump stops you had installed? I see the 2 Series is not listed as a fitment.

Yes. These are exactly what you will receive if you buy the Dinan "Supplemental Ride Quality & Handling Kit" for the m235i.
I believe they are sourced from two different models of the 5 series.

do you have the dinan supplemental ride quality kit installed as well, or just the springs?

Springs and bumpstops as specified in my post above. (#13)

[Drpoomanchu]

I have Dinans + supp ride kit and the car rides great. IMO drop is perfect. H&R's seem too low and less opportunity for aggressive tires to boot. I run a M perf front lip and rarely bottom out although i am careful. $1000 is ludicrous. I installed mine in 4 hrs. Any reputable shop should be more than fine if your uncomfortable with the install. Heres a few pics of the stance.

That looks great! But as fat as shops go i work part time at one here in the valley so i would probably just install it myself haha and where did you get the lip from? Ive been looking for one but honestly $500 for it just seems a but much
