Aside from the tire/wheel specs and coilovers you posted above, what else are you running suspension wise? I have no idea how to do anything suspension related. I know from the newbie section I will probably need a camber kit? Your setup is pretty close to what i'm going for.

edit: I plan on getting same size tire and wheel as you and using tein flex z coilovers

 

Should be a wise choice w/ those Tein Flex Zs, I run SPC front & rear camber arms and rear toe bolt set and my camber is right about -1.0, so a pretty straight setup, has resulted in excellent tire wear for about 60k miles thus far.

FWIW, if you run the exact same wheel specs and drop about the same height as mine I'd run 255/45/18s, there's enough room at the fender and it will be a bit better mount than the slightly stretched 245s.

 

For someone who has never done anything camber related before, is this something I can do myself or should I have someone else do it the first time?

 

If you've done a fair amount of mechanic work then you should be ok and have the proper tools, jackstands, etc. For the rear toe bolt you'll need a dremel tool. Here's a link on the toe bolt and you should be able to find DIY links on the rest of the suspension on site or G35driver.com

When lowering and installing new camber parts you want to get it close enough to be able to drive safely to the alignment shop, when using adjustable camber arms try to get them about the same length as your OEM arms and adjust your new toe bolts about 1/4" further to the outside from center, this should get you at least stable enough to get you to the alignment shop.
With coilovers they don't take nearly as long to settle as do lowering springs, I'd install all the parts, run it gently a bit, if you need to adjust any height settings do it now. The next day or two then take it to get aligned.

Also you might need to call around and see what shops deal with lowered vehicles, unfortunately there are shops that are clueless, lazy, or just don't want to deal with aftermarket camber parts. This is time well spent.

 

Do the tein street basis coilovers fit the sedan as well? On their site it only shows coupe

Looks great! It's begging to be lowered

 

Polloroid, looking good, nice wheel choice, looks almost oem but better!


Yes, same part # covers coupe & sedan, don't know why they don't list sedan, there's quite a few brands that also only list coupe applications but work fine on sedans

 

Hi, first post actually...

I have 2010 G37xS sedan, stock suspension (for now). I purchased some 18x9.5 +38 wheels new from a local guy. I'm looking for tires to install, not really much into the stretched look. It is a square setup and I'd like all tires to be the same size.

I've been looking at the following sizes:

275/40/18 My worry is about front fitment

255/45/18 My worry is about tire stretch look


Any advice?

Thank you,
Drew

 

255/45 won't be a stretch on a 9.5.

Gonna steal blnewt's post from the page before, since I believe that's what he runs.

I just saw that, I had to run through 40+ pages to find a similar setup (other that height)

Thank you

 

255 on a 9.5 is perfect, won't give you a stretched or a bulging look.

 

I run a 245/40/19 +35 square setup on my 13 G37x sedan, what size spacers do I need on front/rear to get a flush look? Also I'm sittin on KSport coils. Thanks for your help!

 

Your wheels should be flush with those specs, but the tires will be sunken in at the fender. You have about 10mm to the fender edge in front but the fender isn't flat rolled in front, a 5mm spacer or a fender edge roll and you could run 10mm ones. Keep in mind you'll have wheel poke rather than being flush.
