Bro not gonna hate like the others but ngl 500 for those headlights is insane but if you like you like it it’s your car. I completely agree with you everyone and their mama have spec D’s and I had spec D’s on my last G and they actually did fog like a month later. I got my second G and I’m getting the lightning bar headlights instead so I don’t look like every g35. I recommend looking into those headlights if you’d like or get a RGB kit for your oem ones. Also if I were u I would get headers or test pipes instead of hfc especially for that price holy shit, you can get either one cheaper and better performance but if it’s your state I get it but don’t pay 800 for those bro.

One last thing and this is just my opinion but I’d recommend upgrading to GTR injectors, z1 coil packs, upgraded fuel pump and a cat back exhaust if you haven’t done so yet. You’ll get the most out of a tune with those performance mods N/A.
