What he said with the optional rear springs we have provided.

Do share a photo or two of your car when you get a chance.

Sure, i recommend running 12mm spacers up front, i'm running 265/35-19's they barely clear the coilovers without spacers.

No spacers up front in this picture and i was running -3.5 camber. It looks much better now with the spacers up front, no spacers in the rear.

The car now with 12mm spacers up front.

Spacers will take up the gap between the tire and fender too!

Anglo i have the competition M4 and it runs 20 inch front wheels 265/30/20 and from what you are saying i would not be able to fit this suspension without spacers as it would potentially rub the tyre ?

I am not a fan of spacers as i am not interested in the looks but only improving the ride / handling

Spacers can be functional as well. If you add them at the front end of the car, the track width is slightly increased and understeer is reduced.

They didn't rub but were awfully close, i'm an inch lowered than stock,at stock height you should be fine.

Ok thanks

The high springs become an issue on the larger bumps when the high rate springs rebound and the shocks have to stop that motion VERY QUICKLY. It's there on the upper end on the rebound stroke that the Ohlins get harsh.

Damping is great though, spot on and very controlled. I think lower spring rates and it will be amazing all around.

Indeed, for the big bumps, the high spring rate is a critical issue, especially at rear. Now I am looking forward to refering the Ohlins recommendation spring rate for F87 M2 and see if any difference.

Would you suppy the rear spring rate which is around 180N/mm?

Yes, rear rate at your choice.

[TRZ06]

After having my Ohlins for about 4 mths now, I do notice that they can be inconsistent.

They feel different when cold and after being driven for a bit. I remember reading in some Ohlin literature that they combat that, but I don't see it.

[dahherwang]

Ohlins has announced its recommend spring rate for M2, front is 90N/mm, rear is 190N/mm, I think this setting will be better than the one for M4 and I personally will see it as Ohlins's unofficial correction...

Now the only thing needs to be noticed is the length of Ohlins M4 rear sping (PN: 48420-83) is longer than the one for M2(PN: 48010-67) for 30mm, which means the assistant springs are necessary.

Nothing official from Ohlins USA so let's wait and see if anything changes.

Thanks!

EDC is a waste of money!

Note to myself: Don't ever get EDC on a future M car.

You're absolutely right!

Personally, my car is a 17 ZCP, I feel with 20 comp rims, the car is really upset on some roads in Toronto.
I really want to have a minor drop and improved handling over the stock ZCP, but I drive the three to four days a week, I also don't want to lose any comfort.

Dude in Toronto you need a serious off-road vehicle to get out of the 401 near tiptop. Its like potholes the size of sink holes.

Still not too far off the 10-20 clicks Öhlins recommends for street.

This is what you pay the money for. Ohlin is top notch. Nothing comes close that is why they are on the Koenigsegg and a bunch of other super cars. Lowering springs are good, but not when it gets to upgrading your suspension to ride better. EDC is ok, but when I use it on my car I find there is not that much difference to the driving quality and you just feel the road more in full sport.

OHLIN is it.

Yes, this is what I worried when I am thinking about any suspension change.
The roads here are just horrible. I was originally toward to the M performance Coilover but the price of part and installation are ridiculous in Canada.
Gonna try my friend's M3 with Ohlins tomorrow, if it suits my taste, gonna order it next week.

Let us know how it went. I am sitting on the sideline looking for feedback as well. Toronto roads are so crappy (even the north is going to hell now) that one has to choose the suspension wisely!
