I'm interested in a comparison between the Dinan and the MP. Anyone have any experience, mainly on track?

In terms of overall times, the Dinan suspension (with camber plates) can keep up pretty well with a full set of coilovers. I'm quite impressed. At least at Laguna Seca.

The nice part is the Dinan’s are soft enough that you can drive over almost any curb to straighten out the corner and it doesn’t upset the car like stiffer suspension will.

I've done 5+ track days with the Dinan, Vorshlag camber plate and Cup 2 tires.

Driven around 4000+ km on the setup and here is my opinion:

Street: They indeed produce a little more compliance over the small bumps and imperfections on the road but I found out that on bigger bumps or broken roads the higher spring rates combined with the bouncy M2 oem shocks you end up getting shaken more than with the stock suspension. With the roads I have around me I will not keep this setup.

Track: Noticable improvement of body roll, turn in and high speed stability, not quite at the level of my friend with MP suspension. I am an aggressive driver and with Cup2's I did find the limit of the setup at my 2nd event but I think its still a very good setup for most folks.

Agreed on this.

So, what’s the Goldilocks setup that is good on track and softer than OEM around town, and isn’t crazy expensive?

I've done a ton of searching in the past days and will probably be going Ohlins with lower spring rates next season if I keep the M2. I looked into KW DDC but front progressive springs won't suffice my track driving

I am eager to try the adaptive suspension on the upcoming M2cs but based on the M4cs reviews it probably won't be that great..

Ohlins with springs based on your personal tolerence/roads you drive on is probably the best solution. I've read with 70/140 springs in the 15-20 cliks range they will be a lot more confortable than oem suspension while still removing roll and giving much better damping/compliance. Adjusting to 0-5 clicks seem to produce a stiff but compliant ride perfect for track driving.

And if your not satisfied, you always have the option to swap your springs for stiffer ones later on. The M2 is my weekend toy/track car and I know I don't use it as much as I would like just because of the pogo suspension and hard wall Cup2's etc. and its making me second guess the M2 wich I should not because its just the best car for my needs at its price point, any upgrade to suit my needs would be at least a 150k cad 911 GTS. GT4/3 is not confortable enaugh for my roads.

I hope I don't run out of patience and try the ohlins, It could be the goldilock I'm hoping for..

Sounds like a good plan.

Would love to hear someone’s feedback that has street driven and tracked the Dinan HAS and an Ohlins setup so we can hear a good comparison.

[PLF69]

I just ordered the Ohlins (70nm + 140nm) kit with matching new Vorshlag plates.

If I'm lucky I will have these installed before winter and I'll report back.

Same here, I loved the KW v3's I had on my F32. But the M2 is my daily and still track it every few months but not my main track tool, I have another car for that which is full blown track setup. So I was considering these Dinan HAS with camber plates for my daily M2 and call it a day. But I don't want to be bouncing all over the place for all my daily commutes.

These are still high on my consideration. Not in a rush.

Definitely interested in the results. The choppy Midwest road really takes a toll on DD the M2.

Body roll is not the job of springs, that's what sway bars are for. Ride height is not a measure of performance, lower doesn't make you handle better. Stiffer springs doesn't make you corner harder.

This thread got a bit derailed.
I would like to bring it back to Dinan HAS.
Another member mentioned he couldn't get anywhere near the drop Dinan is claiming to be possible.

I let the spring settle for a week but I'm still at about 610mm (bottom of the rim - edge of the fender). Stock height is 612mm. I'm about 4mm from the bottom of possible adjustment.

Penis jokes aside, where am I missing that inch?

Lab_Rat, I installed Eibachs on my M2c a month or so ago.

1st the M2c definitely is more compliant stock wise compared to the OG M2 I test drove few times.

The Eibachs hardly changed the compliance compared to stock and I'm very conscious of suspension harshness due to the other cars in our stable like the Tesla (air suspension).

Only issue is, the Eibachs did lower it more than I would have liked for winter use but so far it's been a blast.

*Ok I just read your post again and it seems you already installed the Dinan. Hopefully the above will be of some use for others interested in lowering their M2c.

No, I don't want to slam it. I would like to tastefully lower it by about 3/4 inches. That's less than the M Performance coilovers do. The Dinan HAS is not allowing me to do it despite advertising just that.

The car drives well, I can definitely confirm all the good things people say about ride quality.

But I would like to find out what I did wrong during the installation that I can't come anywhere near the numbers.

Anyone with Dinan HAS, would you be so kind and measure your ride height and maybe note how far from the bottom adjustment on the collar you are?
