yes, you do. I have 285/30/20 dropped on s-tech and it rub like hell. If you have more than -3 camber, may be you won't need to roll fender.

 

if i wanna drop with 350z s techs what else do i need to buy?

 

Most likely, but it really depends on your offset, and to some degree the width of your wheel.
If you have a less agressive offset like a +28 or so... (guessing mind you) than you might not have to. If you have something more like a +15, I would say defintely. I have 285s on a 10" rim, +25. I probably could have gotten away with not rolling, but i did it anyway, just to be safe.

As mentioned above, the degree of camber will help the issue on rolling.
I have like zero camber.... (SPC camber kit)
Actually thinking of putting a degree or so of camber back into it

 

Nothing really, it will work with just the drop, you'll just have mad camber on the rear. Would reccomend a camber kit for the rear.
Might need to roll fenders depending on what wheel and tire combo you have.

Other than that, get to droppin!

 

Thanks for the answer fellas!

 

s techs running 18x10+ to etc etc... 19x10.5 etc etc... youll have to roll fenders i believe...dependin on how thick your tires are...if your running 275 to 305 from 30 to 40....you should roll fenders so you dont rub

 

if i get the 350z htechs, what size wheel spacer would i need for my oem 19 rays?

 

i dunno if you would need spacers for oem 19 rays...i dont think so though

 

I planto get 350Z S techs along with an SPC camber kit for the rear. I won't have any rubbing problems now but when I get new rims I'll have to roll my fenders.

I plan to get 20x9 w 255/30 F & 20x10.5 w 285/30 R. offset 15 all around.
Can anyone verify?

question...how much camber is left after using the SPC camber kit with 350Z S techs?

I know OEM spring rates are 314/427 and 350Z S techs are 386/402, but can you really feel a big difference in stiffness?

 

Z Htechs and 285/30/20 in the back...i had to roll the fenders

 

350z H-techs w/ springmount mod

 

are these 17's?

 

Yes
