Many on here use swift springs to lower their car, it provides the least headaches in regards to height clearance and ride quality close to that of OEM.

I have a set for sale. Brand new in box at my office. PM me, I am in proximity to you for pick up. I have a 2010 G37 awd as well.

 

Nice shot jpg37, what offsets are you running, fit looks well done!

That 245/275 combo won't be an issue unless you happen to run brand new front tires w/ rear tires that are very worn, then the variance may be over 1% but that would be a rare situation.

 

Thanks for the compliments, +35mm offset front, +43mm offset rear. Stock ride height. Sorry didn't get back sooner, went to the NCAA tourney.
