Ok guys how is every body doing I'm new to this forum and need some advice, I just got my self my first 2011 infiniti g37x sedan, I'm looking into lowering and putting some 19's the question is wich type of tires would be best for the rims and if I should go with lowering springs or with coilovers. If guys can provide pic's of your rides that be great..

Here are some pics of my ride stock....

 

Since you have an X, swift springs on a budget or fortune 500 coilovers if money is not an issue. I always recommend Michelin PSS for tires but those are pricey so that depends on budget as well.

 

good advice there ^^
Keep in mind you'll also want to get front & rear camber kits, or at the very least the rear camber/toe kit. The complete set is about $500 the rear around $180. As far as tires, there's some good summer tire choices that are easier on the wallet than the Michelins but those are pretty much the gold standard.

If you live in an area w/ a lot of winter weather I'd consider keeping your stock wheels and use them for a winter set w/ good snow tires then setting up your new set as a performance set w/ good grip summer treads.
BTW, welcome to the site!

 

Thanks guys that's good advice, I think I'll go with springs for now. Wat size tire would be best for the 19's as I read here on the forum that depending on the size it could cause problems with tthe awd system recommendations on that..

 

If you go with a square setup (all rims & tires the same size) a 245/40/19 is the most common. If you go w/ a staggered setup you have to be much more careful, only a couple compatible combos w/ 245/40/19 front and 275 or 285/35/19 rear tires. The 245/285 combo is the best if you go staggered.

 

That great advice thanks...
