Yes, there are however no shock options for the X sedan.

I had 32k miles on my stock shocks when I installed my springs, it was bad from day 1 with the swifts on them. FA500's with the swift upgrade ride and handle extremely well, even better than stock.

Here is a good general rule, don't half *** something if you can't afford it now, save up the money and do it right the first time, otherwise you'll be paying twice for install and for springs.
Thanks for sharing that. I've seen it done a lot here and it does look good, so I was considering it. Given your experience, I think I'll hold off until I can do COs.

my X handles very very well with Eibach springs and KYB struts.. I have no issues with bottoming out.

Would anyone recommend which is a better coil-over setup for the G35X Sedan (2008)? I am leaning towards the stance super sport , haven't really considered Fortune yet. Also heard too many stories on the dreaded clunking sound with the BC's. I definitely want to avoid going springs on my oem shocks as my car is close to 120k on the OEM suspension!

I would agree with you. I changed springs with Eibach at 95k but I do not have any problems with bottoming out. If the car had 120k I would just save for struts and do both.

If you're keeping the wheels, then get a set of 20mm spacer adapters. That will run an additional $200 or more.

Point being, even the most reasonable and least expensive project carries with it added expenses. You can't *just* drop the car... there are a lot of considerations.
I'm curious...

Is there any wheel size/set that won't need any spacer when you drop your car?

If I need to invest $200 spacer for my 17", I rather spend more and get a set of nice wheels that doesn't need spacer!!

Are most expearincing problems with oem sport suspension and lowering or is it mainly the OPs struts on the X that is the issue?

Aftermarket wheel manufacturers all offer different offset configurations, some more than others. You need to research wheel offset. No offense, OP, but if an extra $200 makes you think, "Why not buy new wheels?", then you're simply not prepared to make decisions here yet. So step back, take your time, research, research. Don't expect all the answers to come at once, or even consistently.

I'm running 4 of the g37 convertible rear wheels (19x9 +30 offset) I'm dropped a little over an inch in the front and an inch in the rear and I am completely flush with the fenders with no spacers.

Since you mentioned concerns of cost here is an idea of what to expect.

$1,400 for FA coils, 330 for spc front arms, 150 for spc rear camber kit, $300 for install, $660 for wheels (keep in mind that I got a special closeout deal that will never happen again and you should expect to pay about 200-250 per wheel used, $1,100 or more for tires (245/40/19). So to do it right you are looking at approximately $4,500.

Yep. Absolutely. Heck, a good set of lugnuts alone could run a couple hundred.

You know, if the OP just wants the look of a dropped sedan, and doesn't care about the handling considerations, he could easily just throw on a set of Swift Springs for a few years, and maybe some spacers, no camber kit, no aftermarket wheels... in and out for under a grand, parts & labor. Just saying... he *could* do it. (Oh, and another Ben Fanklin for an alignment, LOL)

Whether he should or not is a personal choice. His, not mine or yours.

I was scrolling down to say this. Its spot on.

I'm in an x on swifts with a well maintained suspension including stock replacement KYBs with no problems and the handling is fantastic. Obviously others' experiences will vary.

But I will add that I am meticulous with making sure everything is nice and tight because I live in a city riddled with potholes that get worse after every harsh winter. Many of the roads in the city feel like those roads manufacturers use to test the durability of their suspension.

My car was scraping/bottoming out/hitting the ground on these roads for years before I added the swifts and whenever I drive any other car on these roads the same problems are experienced.

The KYBs aren't the ones the car came with 130k miles ago. A replacement set was less than 200 dollars and took an afternoon to install in my dad's driveway. it really is a maintenance item. like pads and rotors.

The ride has only been made better on my x if anything. In fact I haven't actually hit the ground/bottomed out ever since i got the swifts. But this may just be testament to my ability to doge potholes getting better/blind luck.

Personally if they're the same price, I'd rather get a higher quality strut and spring that is actually beneficial for the application than a cheap coilover with features I probably wont need or want.

Also, I'd like to add that I F******en hate pot holes. I hate them so much.

My decision was based on my lease and didn't want to place a chunk of $$$ on modding, so I went the least expensive way and I feel that I chose wisely.

Swift Lowering springs is the best choice for the G37x(S) and with the upgraded rear sway bar from the G37(S)/Z.
Adding a GTSPEC FSTB further helped a bit...both in handling and visually.
With 20mm spacers on all four with either stock wheels or like me, I re-used the OEM tires and went with aftermarket wheels in the same size as stock...giving the appearance and handling the G37x(S) should have.

These mods didn't hurt the wallet too bad when time came to return the lease...
plus selling them used afterwards was a non issue.

I have to ask... is the handling on the X/Journey that bad? Very soft and understeers a lot?

Suspension travel is a GOOD thing, if you like your wheels touching the road.

I've been on Swift springs with my X sedan for over 3,000 miles... Have had Hotchkis F&R sway bars along with 19x9 wheels for nearly 6,000 miles. Car handles amazingly well, yes the ride is a bit harsher, especially on Jersey roads. But other than that, it's not bad at all. I even travelled 550mi from NC to NJ with 4 people in car with no complaints. Car has 48,000 miles on it too. I'll either upgrade to coils or just get new shocks/struts once my current ones go. But if you're just looking for a minimal drop, Swifts are fine for the X.
