Hey everyone. I've been doing a lot of research and searching on the forums to gather all of the information that i need but I would just like to get confirmation on a few things before I pull the trigger.

My Car - 2011 G37x Coupe AWD Stock Everything but R2C intake.

With the the nice weather approaching in NE I've been getting the urge to dump some money into the car. My short term goal is to drop the car and keep my stock wheels while setting myself up for new rims in the possibly near future (Looking at 20" Vossen CV1's.)

For the Drop:
I'm looking for a mild and tasteful drop that will still be ok for the winters. Seems like
Eibach Pro-Kit 6394.140 is the best way to go.

SPC Front and Rear Combo: 2 Rear Camber Arms w/ Toe Bolts + 2 Front Adjustable A-Arms (Complete set for whole car front and rear) 72260 + 72130

That should take care of the drop and a realignment a couple of hundred miles after the springs get installed should take care of the camber and toe.

Now when i decide to replace the rims, what I gathered is this to be the best option.
Vossen VVS CV1 Matt Black/ Machined Stainless Steel Lip
5*114.3 Bolt Pattern
Front: 20*9 32mm Offset w/ 245/35 Tires
Rear: 20*10.5 42mm Offset w/ 285/30 Tires

Does that sound about right? Is there anything else I need to consider while doing this? Will it be an issue swapping out wheels for the seasons? Any advice would be greatly appreciated.

 

Good for you for realizing you should get a camber kit up front. A lot of people find out during the install that they need a camber kit. You don't need to drive a couple hundred miles for the springs to settle, it's more time based. In a week or so, you can probably take it in for an alignment. As a matter of fact, I would probably get aligned sooner rather than later. You don't want to chew up your tires.

 

Thanks! Reading up I found that was the best option. I heard the rear camber kit installation involves some drilling into the car. I'm hoping that won't be an issue. It will be done by a professional mechanic. Curious to hear from people with experience in this.

 

The rear camber kit is not ABSOLUTELY necessary, it just give you a much wider ability to adjust the toe to keep it in spec. I had a professional mechanic do mine, and it's more of an art form than a science. What he's doing is drilling out where the spring bucket attaches to the chassis of the car. The spring bucket will be able to move either farther, or closer, to the differential. This lets you adjust toe with the slop bolts (toe bolts).

I had it done, the whole process is iterative. You install the camber kit, widen the rear bolt holes, install the rear camber kit, install the springs, and put the wheels back on. Check alignment, then adjust as necessary ad nauseum. All in, it takes several hours to get everything just right. It's not really something you want to rush, either.

 

Well, if I'm going to do it I might as well do it right. I'm not overwhelmed by the coilovers available so this seemed like the best option for me. Plus, it's not like I'm going to track the car. The way you described it just sounds tedious and expensive. I'm assuming a decent mechanic with many years of experience would be able to handle that.

 

Hey Gorilla, if you're not in a big hurry you might look into this group buy for coilovers from THMotorsports, sound like a good option for you AWD guys~'

As far as the wheels & tires, looks pretty good although I would go up 3mm in the F&R offsets to a +35F +45R offset it it's available, just a bit more room. Tire sizes are spot on

 

Thanks for the heads up. It's good to know that they're are other options in development and I may take that route later.

One more question though if you all don't mind. While I stay with the stock 18 inch wheels and the eibach drop, what would be the best offset to have with spacers to look nice and flush but avoid rubbing? From what I've read people seem to be happy with 20F and 25R.
What would be the best brand and are there any drawbacks to having spacers? Thanks again guys.

 

Here's a good little tutorial on how to measure for spacers
You should be able to get a good idea from that.
H&R, Ichiba V2, and B2Autodesigns all make decent hubcentric bolt-on spacers. Just be sure to use 6 sided sockets when bolting them on, the nuts on the spacers are a bit soft and can round off pretty easy. Also torque to 80- ft. lbs and recheck torque after a couple hundred miles and every tire rotation.

 

AlienGorilla, I'm in the same boat as you. I too live In NE area with an awd G. Instead of coilovers I want to go the lowered springs route. I'm also going to upgrade the struts while I'm at it. I'm still in the process of gathering info on what the best route to go (brands, height, etc etc). I'm leaning towards Swift springs but not sure about the struts. In terms of lowering it, just enough to rid that wheel gap nothing more, not sure the spring height when it comes to that. Or if I need anything else to make everything work properly. Just bought some new tires (stock 225/50/18) so I'm hoping to have this car lowered by mid to late April. Hopefully all snowfall will be done by then but its NE, one never knows. Good luck with your project, hope everything comes out perfect.
