05 G35x just purchased... loving the plush leather and handling.... what next? I guess I will leave it to the experts........ gentlemen??

I am not into huge rims or ridiculous and ostentatious features just some simple upgrades for power handling and tinting...... the floor is yours

 

get lowering springs (eibach, H&R, etc), no coilovers yet for G35x, maybe 18 or 19" rims (chepest would be used OEM's or used aftermarkets off this forum's marketplace), Stillen or JWT pop charger with Z-tube, HKS or some other aftermarket exhaust, clear corners, and of course tint all around....these are your basic starter mods I guess, I'm sure members here have a lot more ideas like FI.....your best friend is the "search" button, everything is here.
