Yes it does exist...and it's SUPER cool driving one of those 7-ers as they have NO body roll no matter how hard you corner. Ok, actually they program in 0.5 degree up to 0.5g lateral, and IIRC it ramps up to 2 degrees at full lateral grip.

BMW uses an electro-hydraulic [sic] coupler that controls two anti-roll bar halves, which is connected to a controller/actuator. It's super cool.

 

Okay, I've decided to go with H&R springs to lower my R56....

Now my question is will I be able to bring camber back to spec off of stock??

If not then which rear control arm does everyone recommend??

I was looking at TSW or Megan control arms...

Help?

 

You don't need anything additional. Use the factory rear lower control arm outer eccentric bolts to correct the camber. The easy way is to adjust them so the knuckle bottoms are pushed furthest towards the vehicle center [most positive camber]. At ride height with your H&R spings, it'll yield about -1.0 degree camber in back.

There's minimal adjustment in front. The strut towers are mildly slotted and can add about -0.5 degrees. Also, be sure to check your front toe, as lowering the front will change the toe slightly. You want to end up with zero toe or 1/16" toe-in.

Cheers,

Dropped and got new shoes!

Haven't cleaned her yet....

 

looks great! What wheels are those?

 

DV, Those look really good

 

Thanks, they are flat black Tenzo M's Version 1...

17x7 +42, wrapped with Yokohama Avid H4's, 205/40/17...

Oh, and the funny thing is I took her to get aligned on Monday... Camber was all within spec! Caster & tow need a little adjusting in the front but that was about it!

H&R's are smoother on local roads then stock but a little rougher on the highway vs. stock...

 

Those are pretty nice looking wheels! I wish they weren't 8 hole universal 4 hole but nevertheless... sweet ride!
