r/350z

2008 350Z Base 6MT here. I’ve noticed my LTFTs are consistently around +14% to +18% on both banks and I’m trying to figure out if that’s normal for these cars.

The car is mostly stock besides:

• Injen short ram intakes
• Tomei single exit exhaust (Stock Cats)

Could the intakes/exhaust be causing the positive fuel trims or making the car run lean?

So far I have:

• replaced intake manifold and throttle body gaskets
• cleaned both MAF sensors
• cleaned throttle bodies
• smoke tested the car with no vacuum leaks found

The car drives fine and has no lean codes, but I’m wondering if it’s still safe to drive with trims this high. Is there anything else I should check, or is this just something I’ll have to deal with until I get it tuned?

Rn my vq is pretty stock besides my air intakes I got a 07 hr at 80k miles and I want it to sounds nice. I was thinking a Tomei single exit with my stock y pipe and berk resonated test pipes would make it sound more aggressive. Thoughts since this is my daily and I don’t really know what this would sound like.

I have been rocking a set of HR headlights with blacked-out housing and iron-man style DRL for a while now. I honestly liked the look at first but, the more I looked at it, the more I felt like the black housing didn't fit the WV2 paint as well as I wanted. I've been leaning more towards an OEM+ look, so I ended up picking up this used set.

The lenses were a little oxidized and had some yellowing, so I decided to restore them properly instead of just polishing them. I went the 2K clear coat route using SprayMax 2K Headlight Clear.

Process was:

• Wet sanded with 600 grit
• Then 800 grit
• Finish with 1000 grit
• Cleaned and prep surface
• Spray 3 coats total
  • 1 light tack coat
  • 2 medium-wet coats

I know some people go up to 1500/2000/3000 or even polishing them before clear, but from what I read, stopping at 800-1000 grit gives the clear enough bite to stick on properly. The lenses looked super frostly after sanding, which is nerve-racking, but trust the process.

There is a little bit of orange peel in the clear (my first time spraying 2k so it might be my technique) but overall I'm pretty happy with how they came out for a DIY job.

Going to let them fully cure before deciding whether to wet sand and polish them later. If anyone has done this before, please leave any recommendations.

Everyone knows our cars have terrible blind spots and im thinking my next mod will be Android Autoplay with a backup camera. Anyone got any recommendations before I go to Crutchfield?

Pulled the trigger on some 275/35/18s to go with a full square setup.

Setup will be:
- 18x9.5” +22 on all four corners
- Font Camber: -3ish
- Rear Camber: -2ish

Suspension:
- Lowered on RSR springs, between 0.5”-0.75”

I know someone running the same tire & camber setup with +15 offset and is fine in the front. Also someone running a 18x10.5” +25 with slightly less camber, and has knuckle clearance issues.

Think I should preemptively order some 5mm spacers and extended studs or should I be clear of any knuckle issues?

How are we supposed to keep these cars on the road (in scummy California) when it costs a total of $5,000+ just to replace stupid air filters... This needs to be pulled back! Classic example of how politicians are out of touch with average working people. The Federal smog regulations should be enough! Why does California have to be so lame... rant over.
