Dinan front spring height

relative4 · 11-25-2019, 10:35 AM

'08 335xi E90. I just switched from 100% stock suspension to Bilstein B8s and Dinan D100-0925s, which are supposed to drop front and rear 1/2". The ride and handling are great, but the fronts are REALLY high - slightly higher than stock.
Installation notes:
New front top mounts
I loosened the thrust rod bushing bolts, disconnected the end links, and drove over bumps to make sure the bushings were settled properly before putting it on ramps and torquing.
In the rear, I did install the plastic spacers between the upper spring seats and cups.
New rear mounts, top and bottom

Any thoughts? Thanks!

Compare new with old and you'll have your answer.

I have the same setup, your rears will settle about another .25-.5 inch. As for the fronts, what's the part # on the hats?

Yes, as @fcobra94 states. Replied to your other thread as well about the bilsteins. Their hush nitrogen pressure also raises your effective spring rate, which raises your car a bit as well

I say go for taller tires and wheels like I did. LoL. I'll be sure to take measurements when I do my Bilstein kit, with OE springs and new OE xi xDrive strut top mounts

Soravia · 11-29-2019, 06:51 PM

What about the bushings etc in rear? If the rear sits lower than designed, the front will sit higher than designed

Chadi335is · 06-20-2021, 09:18 AM

Bumping an old thread....

I just had the same setup installed on my 335is. The shop ordered new top strut mounts with the install.

I have the same front wheel gap - raised 3" higher and not 1/2" lower.

Was this due to the strut mounts? Or something else like a bad install job?

It's the new strut mounts. Mine are GRADUALLY settling down.

Thanks for he update... it's now 1.5years later and they are still settling? I don't think I can wait that long ...

relative4 · 06-20-2021, 08:23 PM

Yeah, if I were doing over, I'd probably go for H&R Sport springs.

Very strange, I've had no issues with ride height after the first 1k miles of settling in. BMW P springs are same as Dinan and I replaced all rubber

relative4 · 06-20-2021, 09:41 PM

Wow, I just looked at those pics for the first time in forever. That was crazy high. They did settle down from there pretty quickly and are now much lower, but still higher than the rears.

fubarian · 06-22-2021, 01:53 PM

echoing everything said here - 335xi, coupe, dinan springs, koni yellows and the bump stop kit, plus all new connecting hardware (mounts, upper, lower pads both front and back) and camber plates... wow the front was like a 4x4 with 19s (235x35) -- it had a full fist worth of space. I thought the exact same thing, "something is VERY WRONG" and had someone come do a spot check.

Now, it's been settling and its now closer to normal. It's not quite there yet, but I haven't driven it much.

How do you guys like the Dinan springs? I have the sports springs and thinking about switching to the Dinan springs and Koni yellows.

They handle well and feel fine, but if I ever rebuild the suspension again, I'll probably try the H&R Sport springs, just to attempt to alleviate the reverse rake.

Is the Dinan spring lower than the ZSP springs? I'm on ZSP springs right now and would like something with a higher spring rate and maybe not as low.

No clue.

Herakles · 07-04-2021, 08:29 PM

Just did dinan and b8s on mine too and the front looks a tad high compared to back overall happy is yours a little bouncy ?

Chadi335is · 07-04-2021, 08:34 PM

It's been 3 weeks now since my install and my 335is is still sitting 1.5 higher ... center bore to under wheel well arc is 14.5 inches. Not happy with the outcome.. I already have an SUV

The font looks much higher than mine it doesn't look right ! I did new strut top mounts too

I'd install some supreme power lowering perches, but yes, it's a combination of the Bilsteins and the new strut mounts I think.
