Best street and occasional track suspension
I am looking for a suspension that is best on the street and occasional track use. Looking for a setup that will tolerate potholed streets without teeth rattling and still be good if I have a hard turn. There does not seem to be much information but the Dinan coilover kit is reputed [by Matt Farrah] to be softer than stock and the Ohlin road and track bills itself as able to quickly soak up a bump and quickly rebound. I really value comfort for a daily driver over the occasional track day so that is where my priorities lay. It may be that I keep all stock and just put on some front camber plates so my front tires are not destroyed during a track day, but I would welcome advice on the best setup that is either adjustable or progressively sprung so that I can enjoy the ride on the hellish streets of Brooklyn and get the most when I get to the track.

either of those would be good. i have the kw v3 and run it two clicks softer than the "normal" setup for daily driving.

I run Ohlins with custom front and rear spring rates. 448/782, I think is what they came out to. There is no doubt that it's stiffer than stock, but it does absorb the big bumps pretty well.
If stock is pushing the comfort level for you, then I would advise plates only. |

they dont. I think he meant to JUST use the stock suspension with aftermarket camber plates.

I would personally hesitate to advise folks that Ohlins on a softer setting "rides better than stock". I'll try it just to see what it's like around 15-16 and report back on this thread. |

An alternative to camber plates could be to use alignment correction bushes in LCA and tension struts that are on car adjustable and add about <1 deg of front camber
Superpro do both - below is camber adjustment bushes for LCAs http://www.superpro.com.au/find/supe...999501545/vid-

F87 M2 is lighter with a shorter wheel base so even lighter springs may be needed to get the same results, but not impossible. Here is the link: http://f80.bimmerpost.com/forums/sho....php?t=1354107 |

Yes, he said the Dinan is more comfortable than stock. However, how is that possible? The Dinan kit is adjustable springs only. No shocks. Do they have a full kit? It isn't on their website.

Alright, so I tried 16 clicks off full stiff, that's 3 clicks softer than I normally run, and I really dislike it. I'm surprised how much of a difference it made. Yes it takes some of the harshness away, but in return, the car has an unnatural feel to it. I'm not really sure how to explain it. It isn't the typical underdamped feeling.
So back to 13 clicks for me. |

I think for $2,300 the M performance suspension is tough to beat.
I went to the track a couple weeks with the factory settings. I was able to do 2 sessions but I was already a second faster than the original suspension. Local track is short, just 2.4 km. then Yesterday night, I changed the rebound and compression shock settings to full soft. And the ride is pretty comfortable. I am now under the impression that the cars ride is more compliant than what it was when stock.

Strangely, Ohlins used to use a much lower spring rate
From a sale listing I found:
Ohlins Suspension For 2007-2013 BMW M3 (E9x) - BMS MI40 product detail information Spring Rate: Front: 60 N/mm // 343 lbs/in. // 6.12 k/mm - Rear: 120 N/mm // 686lbs/in. // 12.23 k/mm This on a car with a curb weight of 3,704 to 4,145 lbs. Strange then that the spring rate for the M2 which has a curb weight of 3,450 lbs. should be so much higher. I wonder if the dampers are so different from this vehicle to those for the M3 that lower rate springs are not recommended? |
