Bought my vert this year brand new off the lot, love the car to death and the hard top is amazing!!! I don't plan to do much to this car..well, I say that to every car but I do want to lower it, not slammed, just a decent drop where I wont scrape everything. Anyone have any recommendations for springs or coils? Seem that every time I try to search for anything it pulls up info for the coupe. Leaning towards some springs so I can find myself some nice rims!

 

One good place to do some research on how to correctly do the G37vert lowering might be Z1 Motorsports in Carrolton, GA (south of metro Atlanta).
They have a pretty extensive website, and I have been to their shop/warehouse...pretty big operation with lots of 370Z and Infiniti G37's out front.

 

Z1 added my Gen 3 intake to my vert. If i do anything else to my car it will be done by those guys. great work and very friendly and knowledgible. I want to lower mine a little as well and when time comes will have them do it.

 

i would take it there, but im all the way in the bay area hahaha

 

Ah yea...SFO.
In that case, just use the Z1 website in Georgia for some research.
Good luck!

 

lol, and if you ever want to take on a beautiful cross country drive it is worth visiting too. IMO

 

BC racing coil overs if you are concerned about an even lowering. There is a thread on feedback with the bc coilovers. The springs (coupe aftermarket springs) will never even out comparing the front to the back. There was a post on using coupe springs but the same issue would be had. The front wheel gap would be more than the rear. Since you care about not scapeing, then doing h&r vert front springs, and eibach pro kit rear get coupe springs is not the way to go.
However this will give an even drop at the sake of not being able to adjust rear camber.

So long story short, bc coilovers for the g convertible.

 

I just got a g37 convertible and it seems pretty underdamped. My ideal solution would be something that lowers slightly, say 0.5 in, maybe slightly increases spring rates from stock but adds more damping which is tuned to the springs. It needs to stay alignable.

I've looked around and it looks like the BC coilovers are still the only game in town for those requirements. Is that correct or is there another option that I'm missing? Any hint about where to get the work done in the San Jose or San Francisco area if I'm not comfortable doing it myself?

 

I got the BC coilovers. Damping is very good on it. However I don't think you will get a .5 inch drop at near full height on the rear. D2 makes some also. At the time in April I did not see any on their page advertised so I'd call them and see.

Any shop that does coupe coilover installs should be able to do it.

 

I grew up in the bay area, lot of my friends got work done at Sonic Motorsports in Mountain View. Excellent shop with some bad a$$ rides parked out front all days of the week. People from all over the bay take their cars there to get it worked on.

 

cereal2k,
Thanks for sharing your experience. By, "However I don't think you will get a .5 inch drop at near full height on the rear.", do you mean that at the tallest adjustment the car will be lower than stock minus 0.5 inches? If so what is the minimum drop, meaning highest ride height relative to stock that I can expect with a BC setup similar to yours?

 

indowanksta88,
Thanks for the tip. I'll look them up. I don't want to go all the way to bada$$ myself, but usually people who have been there can get me where I want to go.

EDIT: It looks like they moved to Milpitas and then to San Jose, but they seem to still be in business.

 

I meant at the tallest height settings for the rear coilovers, you won't get a .5 inch drop. it would be lower.

This is the relative stock height. (taken from the coupe factory service manual) and is roughly the same as the vert.
Front: 28.15" sport, 28.03" non sport Rear: 27.76" sport, 27.64" non sport

I've had the rear coilovers adjusted to 26 1/4 inches high with minimal adjustment room upwards left per my installer. Exactly how much, not sure. If I'd have to guess I'd say up to 26.5 inches.

Camber is about 2.8 degrees with this setup.

I got alignment done with me in the car and with adjustments to the coilover height based on the driver side weight shift to event out with the passenger side height.

 

I thought that the camber spec on these was more like -1.3 degrees on the back and -0.6 on the front, or did I get that wrong.

How fast do you end up going through tires?
Are you using any kind of camber kit and/or is one available?
Unless I have the camber specs wrong or misinterpreted them, it sounds like the BC setup is not entirely turnkey.

 

Camber range should be -1.16 to 0.33 per the 2009 vert factory service manual

Front camber kit only. SPC., same as the coupe.
No rear camber kit.

The rear camber will not be in spec with the BC, the front, perhaps with the SPC camber kit and raising the height.
