Hi, as you can see, Im new here.
And I ask noob questions. I've done a research for tire and wheel size but I can't find the correct awnser. Maybe I will help other with my questions.
so here:

I need new tires for my 2003 G35 and I'm thinking to change the stock wheel as well, I would like to go with 18'' inch wheel.
I don't know what is the best, have all same size all around or get a bigger on the rear. ?! I want large tire, more then the 215 stock but I don,t want to roll my fender. I would like to know what is the best size of the wheel including offset and tire spec. If I get better control with large tire on the rear, I would like a setup that give me a large lip distance like I can see on some picture (Wheel look like deeper) It look very nice!


My other question is the drop. I've change for this car (g35) to get a comfortable car. my last car was dropped with Tanabe GF210 and I was very disappointed. It handle like a go-kart but every hole on the road was a nightmare. I've look on my G35 and look like I have sport shock (red one). As I can see tien H-tech give a small drop and keep ride quality as original.
Again, I don't want to buy a camber kit, I want it simple. If I play with ride comfort I will stay stock, but I would like to remove the big gap between fender and wheel just a little bit.


Sorry for my bad english, and I hope someone can understand what I'm asking

Thank you.

 

I will let Chico answer the wheel questions but if you want a 1" drop with stock ride quality you should consider a set of Z springs. Run a search and you will find a ton of discussion and pics.

 

whats your price range, style preference... and how low do u wanna go.. theres just so many wheel/springs/coilovers out there for the G that you'll neeed to narrow it down,.. go search the pics and see what u like

 

For the price, I don't have alot of money to spend on that. for the wheel I'll take no name brand to save money, and for the drop, I was thinking on only spring option, I don't have the money to spend on a 800$ coilover kit like tein basic. I want a nice look for a cheap price .
I know is hard to find quality a small price but with my experience with my last car, I was able to make something good for low price.

 

you can check out axis's for wheels.. there fairly priced and have alot of different styles... ppo are always sellin stuff on here so check out the marketplace... teins run about 150-180 for springs.

 

Here are some wheels that are staggard and less than 1K they are 19" which I think will help get rid of some of your wheel gap and would look great with a set of 350z springs

I've done a research on 350z Spring, as I can understand the best for the Sport shock sedan is the unrevised version on z spring. But, what is the exact drop. 1'' front 3/4'' rear or 1'' front and 1'' rear ?!
I don't want to go lower because here in Quebec We have alot of Crapy road. and I don,t want to feel it more. For the moment it's perfect with stock setup, but with the Z spring does it lower dramatically the comfort?

 

Here are the measurements:

Comfort level is unchanged. A z spring drop is about as mild as they come. Unrevised z springs have the same spring rate as the sedan sports suspension.

 

Anyone have wheel spec et size for 18''

What is the bigger treadwidth i can go on the stock car, I don't want to roll my fender
and what is the off set of the wheel i need
thank

 

1"-1.5" Drop
8.5" wide up front and 9.5" in the rear if you don't want to roll. Keep your offset ~+40 in the front and >+40 in the rear.

245 front width
you can go up to 275 in the rear with the right offset wheel, 285 if you want to roll your fenders.

 

i wouldn't go so far as to say the comfort level is unchanged... it's definitely a bit different but i would say it's still acceptable.

 

+1

Any change to lower your car and get larger rims/smaller sidewall will change the ride of your car.

 

i wanted a stiffer ride and went w/ a full Z suspension w/ 350z H&R springs

love my drop and if you want a stiffer ride and handling thats why i went that way....

i have 20x8.5 38mm offset 245/35/20 all around and works fine

 

^^^ That looks sick!!!

 

Ok I found my rim
they or 18'' x 8'' with 40mm offset
I'll take all 4 same offset

What is the best treadwidth Should I go on my 03 g35 sedan

thanks
