Just popped into my head, but how does this affect alignment. Like do I need to get the KMAC camber pieces for $380 so I don't roast through tires like no other or will everything still be able to get aligned like normal by just taking it to a shop?

Dependent on your drop. The lower you go, the more likely the kmacs are needed.

A friend installed these last week and said he was rubbing when he slammed it on 19's. He said he's raised it back up and settled on 3" all the way around, got an alignment and no issues what so ever. We don't understand how the OP here - http://www.xoutpost.com/bmw-sav-foru...ng-20x11s.html can have 20x11's and not rub, so I guess I'll have to install mine, lower it until it doesn't rub my staggered 20's and then get an alignment and hope for the best that the shop will be able to get it back into factory specs.

If the coilovers change the angle of the suspension to the tire your alignment specs will change. They may or may not be out of spec.

If one of your goals is to lower your X that will increase positive camber which means the inside of the tires will wear more than they were. How much depends on how much you lower the vehicle. It is possible to lower the vehicle to a point that the maximum positive camber specs can not be attained.

I have a set on my 4.4i. Chelsea and I put them on about 6 months ago, because the prototype set that were on it, weren't valved ideally. They're excellent. A lot of adjust-ability, and they hold up great. The prototypes had about 50k hard miles on them(long-distance towing and occasionally jumping the truck!) and the shaft seals still looked basically new. I highly recommend these coil-overs for any car, as they punch way above their weight-class, for what they cost. Also, I'm fairly certain they'll do custom spring-rates/valving for little to no additional cost. They really are an excellent product

The ride is going to be completely different. Much much stiffer. When going up my drive way my X 3 wheels. I have 14k/11k spring rates. I'm going to a lesser rate to get lower

What are the stock rates? This is all I can find on Google - Tuning Developments. You posted on another thread about you having "extreme drop" but I didn't see that option, so I bought the set like the ones posted on the Amazon link.

Per your own thread, I thought you did the stock offering from BC of 9 front / 12 rear?

That was the original plan but they told me I would need stiffer springs beecause of rub. Just a little update, my driver side axle snapped because of the angle it was on due to lowering. Had it repllaces with a remanufactured one. Mine were ooriginal with 125k on them. Not saying it's going to happen to you but just a little fore warning.

Regards to deflating the rear bags, you have to deflate if you install the coils I just disconnected the lines on the top of the bags and removed the fuse for the air suspension system . im also planning to do a universal air suspension bag over coil system to get maximum lowzzz . just have to figure out the clearance issues because of the width of the bags

So you've got stock BC Racing spring rates and it's still too stiff? I told my buddy to reply on these threads about his results. What about you mentioning your kit being called "extreme drop" vs the setup I bought? Interesting and noted because I'm also going FI at the same time. Guess I should be getting ready for things to pop

Yeah, my buddy said he did the same thing and then he's mailing me the links I posted above. Once I get in there to do it, it'll make more sense to me.
