STU Build- headers, lsd, wheels?
Ok so I'm moving along on my build (2003 track edition) stock lsd and will update a full walk through when I'm finished.
Have uprev tune, camber, etc etc
Question here is......STU build
I have 2 front wheels perfectly fine and tires also. Rear wheel is bent so I have to replace 2 wheels at rear
Not a daily driver
So do I do long tube headers, lsd, or all new wheels with the tires on back?
Which mod to do now??
I can swing all 4 wheels/tires new or long tubes or lsd?
Which would you do? I'm now leaning towards I should get 18x9.5 budget wheels for the rear on potenzas and a rear differential but since I have no idea what is in the car currently I've thought about just waiting on it to go out and going towards the Headers and 4 wheels/tires selection. Decisions decisions

Well getting ready for this aspect>>> I've raced on this track several times already but waiting on STU ready Already doing hpde and enrolled with NCM tracks instructors so that's why that option wasn't included. Racing and driving aren't new to me. Nissans and vehicle autocross are.

My instinct is to fix broken stuff first. (At least broken stuff related to how the car performs on the track.)
If the wheels need to be replaced, I would do that and get 10.5" wide wheels. (Or 11" if you can get them light like the RPF1 10.5's are.)
9.5" wheels are kind of small for an STU Z.
The stock diff is crap though, so it should be high on the list too.

Trying to understand the lsd part on these cars as mostly I was into mustangs and camaros, changing rear ends etc. for autocross and on track going to a different lsd does that change the actual gearing In these cars?? I see many go to a 4.08 but what is the process and good gear that's going to be very responsive on a track where I'm generally seeing now I would always run in second gear.
To summarize
Does upgrading to a nismo or aftermarket lsd change the gearing as well??
If not, what gearing would be good for what my goal is?

You can upgrade the LSD without changing the gearing. Gearing change isn't STU-legal, anyway.
I've been told that a proper LSD like the OS Giken should be damn near at the top of my mod list, but it's not budget-friendly. So far my only mods have been 18x10.5 RPF1s, HFCs into a Motordyne XYZ and a custom single-exit, and S-Tech springs (previous owner). I have some other suspension bits in the garage, but unless someone makes me an offer I can't refuse for a diff, that one is further down on my list due to the budget.

If I were going to buy all new wheels/tires for around on the car I was looking at 9.5" so I could run it as a square setup.
11" seems like a lot to me given the gearing and power of this car.....?
