what would be the best way to lower my g35 coupe with 20" on the car without the wheels cambering in?

 

Buy my Eibach_pro kit springs...It is a moderate 1 inch drop... Any lower then that, you will need camber kits.

 

did you have to roll the fenders or anything?

 

Get the 350z springs

 

Not needed...Only if you run a semi aggressive set up would you need to roll the rears...This is a pic with the springs im selling, with aftermarket wheels..

 

The best way would to buy camber kits. Any slight drop will cause some sort of cambering in. Believe it or not the G has a degree of negative camber from the factory. So you're already running negative camber.

 

You'll need a camber kit with any kind of drop. Front should be okay but the rear will definitely need a camber adjustment. If you've got the money, get coils. If not, Eibach and Tein springs seem to be the most popular around here.

 

There is no way to lower your car without the wheels cambering in. Our cars come with negative camber. The question is simply how much camber you're going to have.

I'm assuming you don't want camber because you're afraid your tires will wear faster. However, toe (which no one ever seems to ask about for some reason) will wear your tires out. camber just makes them wear unevenly because of the amount of contact patch. Obviously, if part of the tire is not on the ground, it won't wear.

Other important factors are wheel size, weight, tire specs, and type. All of these things affect your tire wear.

Lastly, you may not ever need a camber kit. You may not ever need a fender roll. You have to actually DO it first. If you have crappy offsets and widths, your tires will not even come close to the fender when slammed. Example, I can tuck stock 18's or 19's with no concern of fenders. Keep that in mind too.

 

This! I'm running 350Z springs and still needed to get F&R camber kits due to camber wear. Thought I would be cheap and be "okay" with just a 3/4" drop, nope.

Yes toe was originially set correctly by Infiniti dealship, so the inside wear was from too much camber.

 

On my sportlines im running which is a 1.8-2 inch drop...I have only a rear camber kit...
A front is not needed since there is enough adjustment for TOE to run O(factory toe bolts)....neg camber of 1.9 degrees in front,and 2.8 degrees of camber in rear...With toe zeroed out all the way around...Toe is the killer...

 

You should be able to get in spec or very close with just 350z oem springs. I personally wouldn't buy a front camber kit for that setup, the price is huge for something you should be able to get toe in spec and very little camber with the oem adjustment.

 

Exactly^^^

 

"Should be able to" and reality are two different things. That mild drop originally put my front at -1.5 degrees of camber (just outside of spec). With a set of SPC arms, my front is now at a more tire friendly -0.1 degrees. For the rear, I'm at -1.7 deg (from -2.2) using just the SPC arms and OEM toe bolts.

I drive mostly highway, so I tend to notice things like camber wear sooner than most.

The point is any drop on these cars will cause them to camber in.

 

-1.5 degrees is barely any camber, and with 350z springs I doubt it couldn't be brought closer to spec by a skilled technician. You are running -0.1 degrees of camber? Why? Our cars were designed to run with more camber than that to keep it's handling capabilities. And I have yet to see anything suggesting such a small change really makes that great of difference in tire life, especially when you consider the price of the front camber kit and how many miles you would have to drive before you made back your money.

In any case it is widely known that toe eats tires up, not camber unless extreme.

 

Xet is right...1.5 is no big deal...Toe is the tire killer...
