Chobble19 are you using the 350Z Htechs or the G35 Htechs. From the drop you listed it looks like you got the ones for the G. The ones for the G have a very low spring rate..lighter than stock. This could account for the rubbing.
G 324 front/260 rear...Z 358/375. Here's the link for spring rates and drop.

hey i am using the h techs for the g35 sedans which are different than coupes.....that spring rate on the rear of those z springs are toooo high for my sedan

 

I didn't know what you were looking for. FYI the rear rate for the G sedan with sport suspension is 342lb and the coupe is 427lb, If you started out with the sport suspension you would be going form 342-375 with the Z h-techs. Just trying to help with you're rubbin' problem.

 

i gotcha but my fenders are rolled so problemo solved! i am thinking of tokico shocks along with getting my 19's chromed, sway bars, tie rods, front lip, my headlights painted +++ i dont know where to start the list gets longer everyday!
