Hello, I’m looking to lower my car on some lowering spring and want to know what you guys recommend for an 2012 g37x sedan. I know a lot of people recommend swift but personally I want to go lower than the swift springs without having to spend a load of extra money on a camber kit, any suggestions? Or should I just say f it and get swift springs. Any advice is appreciated, thanks!

 

Dropping your AWD Sedan any lower than the swifts is fine for a hobby car, but for a daily driver not so much. The lower you go the more problems you will unearth, requiring camber arms and repeated alignments to dial it in, as well as scraping your exhaust and undercarriage all the time. It won't be long before you start thinking coilovers are the solution. However, since you're already concerned about cost, then you answered your own question.

f it and get swift springs.

 

I appreciate the advice, seeing that I’m still on Highschool with not too much money to dump into the car yet I think I’m just gonna have to go with your advice, I plan on keeping this car for as long as possible so for the meantime I’ll just do swifts. As for fitment with stock wheels would 20mm z1 cnc spacers be good? I don’t want to be low with my wheels sucked into the car lol

 

I use 15mm spacer adapters in the winter, with the OEM 18" sport wheels. I don't know what to advise for the 17" wheels, if that's what you have.

 

I have the 18” Enkei wheels, non sport

 

Without the sport package, the Sedan came with 17" wheels, unless someone swapped.

15mm or 20mm spacers... I suspect you'd be fine with either. But first lower the car, then assess plans for spacers.

 

Swift drop being only 1.2" or so, you already need front upper control arms, rear toe bolts and camber arms if you want a decent alignment. Stock suspension with swift drop will yield like -3º or more camber and will destroy your tires over time. If you drop even lower, you will DEFINITELY need to spend on camber and toe adjustments. Also, even with the mild drop, it messes up the front axel angle a bit, so be ready to buy at least one new front axel every year, your CV boots will be blowing regularly with daily driving. Some people upgrade to the slightly longer and stronger m37x axels to offset this issue. I've been on swifts for close to 10 years now, and finally thinking of going coilovers, but I will not be going lower, the drop is perfect already.

Also, keep in mind, because of the way the front is set up, it's like a 4 hour job to install the springs, so be ready to spend $$ on that too. A cost most people don't consider. Something you can certainly DIY if you have the skills and the tools, but its a full weekend of swearing and hating yourself if you do.

Random pics of my x on Swift's so you can see how it sits.

 

Heh, the shop that did my coilover install kindly asked me to not bring the car there anymore. Apparently they really struggled with the install, and had given me a ridiculously low quote to do them. I don't think they made any money with how long it took them, lol.

 

My apologies as I thought that I responded last night from my phone but I don't see the response.

Note that Swifts will settle beyond their advertised drop within a year or two. My guess is close to .5 inches. Maybe this is related to the dampers being a little tired (76K miles)? Not sure, but I cannot imagine being any lower on RWD without alot of drivability issues; AWD of course sits a little higher, which is needed in inclement weather. I run hub centric 15mm spacers all around as Rochester mentioned (zero issues), but if I had a do-over, I wouldn't hesitate to run 20mm all around.

As Hexotic mentions, you must factor in adjustable upper control arms (UCA) and adjustable rear camber arms and toe bolts as I was one that believed the people who said that both are needed only when the drop is more aggressive than Swifts and that a "close enough" alignment is all that's needed. I spend a year wondering why my gas mileage was suffering and also trashed a set of rear tires in the process. Once it was back in spec, it felt like an entirely different car with distributed camber and Toe offset that was close to 0.

 

Yep, saving a bit up front will end up costing you more in the long run

 

I’ve been looking at camber kits and like I said before I don’t want to spend a fortune, I found a 4pc camber kit by godspeed
here’s the link: Godspeed 4pc camber kit
would this kit be alright paired up with toe bolts? I’m worried about the quality since they’re on the cheaper side.

 

I honestly don't know much about Godspeed products. If it were me, I'd probably wait a little longer and go with someone like Mevotech or Moog as both rebox popular SPC parts: https://www.myg37.com/forums/brakes-...trol-arms.html

Camber wasn't a killer for me when I lowered and did the "close enough" alignment many recommend with Swift springs. Toe was terrible though as it destroyed my rear tires and gas mileage. I recently went more aggressive on the camber after installing the chrome sport wheels, so I'm now at the edges of the couple max camber spec, but with close to zero toe.

Also, Swift springs settle about .4" beyond their advertised drop, so keep that in mind. Not sure how some folks manage with the car any lower.

 

Stay away from the Godspeed suspension parts. They are VERY prone to coming loose and "readjusting" themselves, in a bad way. SPC should be the bare minimum. SPL and GKTech are better and more expensive. I speak from personal experience with all of them.
