If I'm not mistaken my RS7.0 came lowered already but I'd like it to be at least another 2 inches. Having ZERO experience with this I don't even know where to begin. I don't want it slammed or too low that I can't clear speed bumps. I keep seeing "air ride" but I thought you just bought new springs and that was all it took? What are some options and what do I need?!?!

 

Springs is your basic method of lowering, and yes it's as simple as buying new springs and putting them on.

Next level would be coil over suspension which replaces the shocks/struts and springs with new pieces and has adjustable perches for the springs so you can dial in exactly the amount of drop you want. But you have to jack the car up to adjust it.

Next level is air suspension. This usually replaces your front struts and all the springs. The springs are replaced with air bags that are filled and deflated from a central tank so that the ride height of the car can be adjusted from inside and while driving.

These are listed in order of difficultly to install, maintain, and cost.

If you want to go down another 2 inches your looking at a 3 inch drop from factory stock. Not many springs go that low so you might be looking at coil overs or air. But I would suggest measuring from the lower edge of your side skirts to the ground. I think you'll find that it's going to put you very close to hitting on speed bumps.

For an example, I usually ride with my tires about 1/2" below the fender lips but I cannot clear most speed bumps at that height unless I go very slowly. Fortunately i have an air suspension setup so I just raise my height to clear and bring it back down later.

 

Thanks for the info. During a break in the weather, lots of rain last couple days, I checked the gap. I have a 2 finger gap, about 1 1/2 inches, in the back between the top of the tire and lip of the fender and even though I can fit both in the front it's more like 1 1/4 inches there. I feel like it would be silly to just swap in the back to get that little of a difference so I would still do both. Any suggestions for the first two options? I would be happy with leveling it out and then an additional 1 inch drop. I think if it was 2 inches like I originally said I wanted would rub.

 

I would look at the Tanabe DF210 series, they give a drop of 1.7" F and 2.1" rear. This will get you close to the drop you want and even the rear out with the front.

 

You sir are a gentleman and a scholar.

 

2 more questions.

1. I see that they also have a 2.4/2.6. That is lower correct? Would that level me out and is it too low that it would rub?

2. Would the 2008 springs work on the 2010? I'm seeing a lot of different years listed (08-09, 08-13, 08-11) and I thought maybe they are so similar that in theory maybe I could use them. I'm trying to save all the cash I can so I can put it towards other parts I'm wanting.

Not sure where you're seeing the 2.4/2.6 drop. Yes, it will be lower but not quite as evened out since there is on .2" difference between the front and rear springs. As for too low, you will need to measure 1.4/1.6 inches below where everything sits right now to see if that's too low for your driving and roads.

As for the links;

The first set is for a tC so will not fit at all

The other three are all the exact same. All xBs, 2008-2015 have the same suspension, the only changes where cosmetic.

 

DF-210s are dope! I have no problem with speed bumps. Also had my fenders cut/rolled cuz im going lower. Even without them, i had no problems with rubbing.
Im about to catch some shade, but im installing racelands this weekend. I'll post more pics.
Here are some pics of the DF-210

my experience is that lowering springs installed on stock struts tends to produce a pretty harsh ride. Here in western NYS the roads are riddled with pot holes and terrible pavement..so a bad ride here will send u off to the dentist....I think the adjustable coilover route is a smoother way 2go....more expensive tho..
