Did you stick with the spring rates that they come with. Don't they come with rather soft rear springs?

I mentioned that in my review. I am not of the opinion that it is necessary to go with stiffer springs, they are excellent as they are. Of course, if your objective is to mainly track your car on very flat and even race circuits (I don't do that, as the Nordschleife is anything but that), then there may be an advantage in going stiffer. Otherwise I don't see the point.

Don't you have the M3 rear roll bar? That might be why the rear doesn't feel too soft in lateral transitions. How is rear end squat under hard acceleration?

I have loads of M3 pieces, not only the rear ARB but also the bushings, so of course that may contribute.

However, I would always give the standard springs a try before swapping them out, as Öhlins developed the kit like this and I do believe that they are competent enough to know what they're doing. If you still find it too soft, you can always change the springs later.

Does anyone knows if the Ohlins are gas pressurized or emulsion? Someone told me they are gased but I couldn't find any reading about this part nor I could find a gas inset valve on the shocks or struts.

I can see a damper on your diff. Who makes them? Does it work? Did you changed your diff bushes? Thanks for sharing.

Looks like he has DEFIVfab differential lockdown kit which eliminates wheel hop. This is a new product that is getting great reviews.

Hi Alpina_B3_Lux, which set of coilovers gave a better time at the ring?

[playground]

nice review, always wanted to see how ohlins performed on e90s...

I don't measure my time around the Nordschleife, as this is the first (big) step to crashing the car.

But as indicated in the review, the Öhlins suspension feels much more solid and confidence-inspiring than the Bilstein, in particular due to the absence of any lateral movement of the rear axle which I noticed with the Bilstein.

For me it is therefor clear that the Öhlins suspension allows you to be much more at ease with the car, which in turn will allow you to go faster with it.

I did change my diff bushings to solid ones and the black rod is not a damper its a tie rod that connects the bushing and diff together. I would recommend this kit for anyone experiencing wheel hop or who is running higher boost pressures.

there is no NVH the install is pretty simple once you have the right tools. The kit is well made and the customer support is unmatched. It comes with install directions also. you wont be dissapointed with this kit.

it doesnt you can check out the reveiws on *********** and no one has any complaints of nvh. If you had solid subframe or transmission mounts then you will have a ton load of nvh.

And I think I am thread jacking. Lol

Sorry Alpina_B3_Lux

Getting ready to pull the trigger on a set of Ohlins R&T with 336 front springs, 616 rear Swift springs, and Vorshlag Camber plates. This is after researching AST's, TCK DA's, GC DA's, KW V2's, V3's, etc. 95% DD, 5% track. Not completely confident in the spring rate choice, any thoughts on going stiffer in front or rear?

[Phil325i]

Why not try the Ohlins-supplied springs first, and only change to another rate if you're not happy? I'm very satisfied with mine (road use only) and the OP is also happy with the Ohlins springs...and he regularly drives on the Nurburgring! (See post #24).
