I want to get rid of the SUV gap over my tires....but,
car s a daily driver so I don't want it too low or stiff.
Anyone with experience please give me some input.
I don't want it so low I have rubbing or camber problems.
I have heard some people used the H Tech for the Z?
I'm running 18"'s - 9"f w/ 245/40 & 10" r w/ 275/40
Thanks!

s-techs should be fine for you since you're riding on 18's. the h-techs won't lower your car that much if you want to get rid of that suv gap you're talking about.

Thanks!
Wouldn't you want to transfer more roll stiffness to the rear of the G coupe?????

"I like you.....You remind me of myself when I was young and foolish"

 

Yeah, transfering roll to the front will increase understeer. A few percent change won't be noticeable though. I am about to put the 350z H Techs on my sedan (should lower 1.3f and 1.2 rear with only 3% roll stiffness added to the front). I am not sure how much these would lower your car. I think .2 in the rear and probably 3/4 inch in the front on yours. Contrary to popular belief the front springs are not the same on the z and the G coupe. The rears are the same length though, so I am pretty confident about the .2 in the rear. There is another coupe running 350z H techs in this forum. I suggest you run a search or post a question like, "Anyone running 350z H techs on their coupe?".

Off subject, what do you fly?
