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.
