Noob question for you guys. I did a search and couldn't find anything. Can I go 19x10 in the rear? And if so, what offset do I get? If not, whats the widest I can go on the rear. Im planning on lowering my car on the Tein S techs for the 350z also. Thank you in advance.

 

not sure 19x10 will fit, but i know 19x9.5 does. I have them on my car.

 

G35keg what kinda wheels do you have? Also what offsets?

 

I'm pretty sure we really haven't seen 10" rears on the rear for pretty good reason's. One may be even greater difficulty getting the right offsets required to not rub. Your best bet is to go with 9.5" rears going no lower then 45mm or 55mm with offsets.


Just to make sure you know the actual drop amount your looking at, it would be 1.7"/1.6", since all 350Z based springs lower the sedan a additional inch on top of what they'd drop the Z. If your sedan is a non sport absolutely do not install those springs with the oem non sport shocks. We have one member that is running his sport suspended sedan with RSR 350Z springs, however 350Z S-tunes are stiffer still. Even with the sport shocks on the car, I still predict some issue's tied to shock control. Investing in Tokico D-spec shocks should be considered, now or down the road.

Tein H-tech's would drop a sedan 1.3"/1.2"
RSR 350Z springs would drop the sedan 1.6"/1.6".

(To know how much stiffer the springs below are over a NON sport sedan, add 10% to the stiffness numbers listed in +%)

Tein S-tech 350z (fronts are progressive, rears are linear)
Spring rates in lbs 386/402
Stiffer then oem by F+23% R+16%
Transfers +7% roll stiffness to front

RSR 350Z springs (just a wee bit progressive F&R, maybe one coil is progressive)
Spring rates in lbs 345/417
Stiffer then oem byF+10% R+22%
Transfers +12% roll stiffness to rear

Tein H-tech 350z (fronts are progressive, rears are linear)
Spring rates in lbs 358/375
Stiffer then oem by F+14% R+11%
Transfers +3% roll stiffness to front

 

Thanks gsedan for all the info. I do have the sport suspension. I would like the ride to say close to stock as possible. When I do go with the 19s I would like the lip to be flush with the wheel well so which offset? Does that depend in the wheel? I would also like stretch the tire just a little bit. Now should I go with the RSR so I don't get a "rubbing" issue?

 

Well, you should feel a firmer ride quality with all the springs mentioned, this is to be expected since your lower and want some added protection against bottoming out. Adding on the Tokico D-spec shocks I mentioned ealier would actually improve ride quality since the shocks use much better valving then the oem shocks do. Also the Tokico shocks are double adjustable. I've actually driven a sedan that has the shocks and I was very impressed. Though they did not offer the stiffness I thought they should given what Tokico said to me and where the shocks were set to.

You should get the flush look your after with the 38mm on 8.5" in the front and 9.5" on 45mm in the rear. I would not run narrower in the front then 245mm or much differance in front to rear tire heights.

 

THANK YOU VERY MUCH Gsedan!! You answered all of my questions.
