I'd love to go with the Ohlins on my car, but I can't find any confirmation that they don't work with xDrive.

The newest version is xdrive compatible. The same part number is also for the G2x 3 series.

After discussing it with the Ohlins rep, and running corner weights and spring rates analysis numbers with the Swift springs rep, I settled on leaving the rear 16k springs alone, and swapping out the front 6k springs for 8k Swift springs (and going with 7" rather than 8" length to allow for raising the lower spring perch to free up some space for wide tires). This made all the difference in the world; on track, the car is perfectly balanced and neutral.

For all...

I just tried to mount my square summer wheel/tire setup:

255/40/18 Continental ExtremeContactSport
18x8.5 APEX ARC8 18x8.5 ET38
BMW camber correction wheel hubs for an additional 0.5 degrees of camber

This would not clear the updated Ohlins R&T kit at all.

I used a 5mm spacer and it barely cleared by 0.5-1mm.

The spring perch is the part that is rubbing against the sidewall of the tire.

I'm not surprised.

The tyres are 30mm wider than stock, and you are running camber correction hubs which obviously change the relationship between the wheel/tyre and the macpherson strut rather than camber plates which change the angle of the entire strut / hub / wheel / tyre.

Taking that approach increases the likelihood of components coming into contact.

I agree.

So the Millway street version camber plates weren't available when I went the route of the -0.5 wheel hubs.

I'm inclined to actually purchase the +0.5 wheel hubs. Based on some very basic trigonometry, I think you would gain an additional 5mm of clearance by going with +0.5 wheel hubs.

Also note, that the new updated Ohlins R&T kit does have shorter springs. 180mm vs the original 200mm length from the initial kit.

Interesting that Ohlins is now shipping slightly shorter springs.

The lower part of the damper bodies (located in the wheel hub carriers) are not threaded quite as high as I'd like - they don't have quite enough height adjustment range to achieve the stance that I wanted for the car.

Shorter spring may be able to compensate for that, as long as the spring rates/length can still provide enough suspension travel and the damper pistons remain in their operating stroke range relative to the damper bodies.

Has anyone noticed that there are now two Ohlins coil-over options that supposedly fit the 2016-2019 x drive?
I ordered the kit that also fits the G series, but the original kit that used to not fit x drive apparently now does.

Yes because shocks that fit xdrive in the front can also fit RWD. But front rwd shocks are too long for xdrive and hit the axle boots. I have the ohlins for xdrive. They ride great. Taking them to autocross tomorrow too.

Do you have part #BMSMU00S1?

I believe part #BMSMP00OH was the first option for the F30, but was not compatible with x drive. Now, per ECS and Turner websites, this part number is compatible with x drive.

Ohlins also changed the spring rates. The old part was like 340 lb front springs and 900 lb rear springs. The new xdrive compatible ones are 450 lb front and 800 lb rear springs.

Some people complained the rear was to stiff. I have a set of the original and before even installing I swapped to 375 lb fronts and 750 lb rears. For street it's feels like stock just more control but I've taken it the track a few times and it's a bit soft. I might swap in the original 900 lb rears and order a set of 450 lb fronts. I think Ohlins got it just right this time around.

Yes that's it. Whatever rates are in it now are really good. Car handled well for two laps at autocross. Then a heater hose blew .

I had the bars changed to Eibach units and have found them to be a far better match with the Ohlins spring rates.

I bought H&R ARB, but reading different opinions, I think they wont be adecuate for me. In you opinion, should I install the front H&R bar and rear Eibach? or buy both bars from eibach? Thanks.
