The car looks awesome! I actually like the looks of slotted over drilled. Did you have to get any other hardware to get your car in spec with regards to the alignment? If I remember, I think you have lowering springs.

I needed nothing for my alignment and yes I’m on Eibach springs. This is the alignment after springs.

Looks like I'm ordering the Eibach springs again unless @traska_rz34 wants to sell them back to me 🤣

That ride height, or stance as the kids call it, looks perfect!

Mate that is sitting just perfectly, looks epic sometimes I regret not getting white.

How much did you drop it? Stance looks perfect! 100% I’ll be going paragon best option out there and endless.

It's on the Eibach RZ34 spec springs with a 30mm drop(1.18 inch). It sits perfectly and I wouldn't want it lowered any more than this. Not into the "No wheel gap" thing.

One more quick question, was the ride stiffness the same as OEM or less? It may seem weird to some, but I like the stiffness of the stock OEM feel myself, wouldn't want to lose that.

Yeah looks epic I’m surprised it’s just a 30mm drop, I struggle to not scrape the air dam going into my garage, always have to go slow and in an angle so 30mm isn’t too bad.

This was the most important thing to me as well! I felt like it became a slight bit softer but when pushed felt exactly like stock springs. Eibach is progressive springs. If I had it my way I wish the stock springs were 26-30mm lower. I would never change it because it's perfect.

Sell me some Eibachs!
Is this a return to sender situation? šŸ˜‚ I actually sold the Eibachs to a local guy that had a buddy that installed 350Z springs on his Z by accident and slammed it into the ground.

I LOVE my Arks. I was soooo against lowering it but I'm very happy I did now. I need to get an alignment, likely later this week, but love the ride and the height.

if you want OEM feel and just a slight drop look at the RSR springs. Made in Japan and super high quality, gave my 2024 performance the perfect stance.

Matt Farrah, for instance loved everything about the auto Z Nismo but just wanted a decent manual to elevate his feelings further.
You made me go and watch both reviews again... very good observation.
In the car & driver article that he wrote, he actually admitted that driving in a canyon road, it would be way better to be in the AT considering how unexpectedly faster he was driving.

'24 Z Nismo
I knew 99% the master cylinder was different, but searched parts.nissanusa before I posted to be sure, that and saw that the booster and ABS module are diff as well. Z1 sells a front NISMO swap with what I assume is all OEM parts, unless you choose diff rotors, and it comes with new dust shields, hoses and hard lines as well. I don’t know enough to judge what effect NOT changing master cylinder, booster and ABS module would have, but being itā€˜s brakes, I’d want to know before I did the swap.

Also curious whether the new front rotors are THE EXACT Nissan part used on the GT-R. If it is, whether it’s the exact part, or the rotor and hardware with a slightly modified hat, guessing it would be the early R35, as those are 380mm, where later GT-Rs have 390mm. If that’s the case, they’re $1,350 per corner from Nissan. Yikes!

Although after looking up GT-R parts/prices I’m not as curious about it anymore. I don’t see myself spending $3K for a front set of rotors.
I had a '15 R35 GTR and did a light track day. The oem rotors didn't fair well. Stress cracks at rotor drilled holes. Had to replace. Subsequently researched rotor designs, and recall reading that the drilled approach prone to this type of weakness.

Here's what GPT had to say when I asked about considering for my '24 Nismo...

"Your R35 experience is a valid warning sign, not paranoia.

Cross-drilled rotors can work well on road cars, but on track they are more prone to cracking because each drilled hole becomes a stress concentration point during repeated heat cycles. That is especially true on heavy, powerful cars like the R35 GT-R and tuned Z platforms. Track users commonly prefer plain-face or slotted rotors over drilled rotors for durability under repeated high-heat braking. (Pedal Commander)

For the 2027 Z NISMO, Nissan is reportedly moving to GT-R-derived two-piece iron-aluminum front rotors, reducing front weight by about 19 lb and improving cooling for sustained track sessions. (The BRAKE Report) That sounds attractive, but I would be cautious if the new rotor face is still drilled. Your exact prior failure mode — stress cracks from drilled holes — remains the issue.

My recommendation for your locked Z build:

Best practical choice: stay with your Stage 2 plan: DBA 5000/T2 two-piece rotors + Ferodo DS2500 pads + stainless lines + Motul RBF600. The DBA T2-style slotted/non-drilled philosophy is more consistent with what you learned from the GT-R: improved cooling and bite without introducing drilled-hole crack points.

2027 GT-R-derived rotor upgrade: worth watching, but I would not automatically choose it until confirming whether it directly fits the 2024 NISMO calipers/hat offset; and replacement ring cost/availability.

Bottom line: your instinct is sound. For repeated hard use, I would generally take a high-quality two-piece slotted rotor over a drilled rotor, even if the drilled rotor is OEM/NISMO/GT-R-derived."

DBA has 5000-series for the NISMO? About time!!!
They’ve had 2-piece for Perf front (355mm) and 1-piece (4000 Series) for the rear (350mm), but I haven’t seen anything for the 380x34NISMO.
They do have 380x34 for the front ā€˜09 GT-R, but it hasn’t been confirmed that’s exact fit on a Z NISMO, whether ā€˜27 or ā€˜23-ā€˜26 (also unsure if the rotor specs are identical on the ā€˜27).

On point, I have seen plenty drilled rotors with stress cracks on the track, on other cars, but the slotted rotors worked best, never similar problems, two-piece will save weight added plus. Our Zs are not light cars.

Good catch...it appears not fit Nismo.

GPT update:

"Short answer:

No — not necessarily.
The DBA 5000/T2 rotors we originally discussed were based on the 2023+ Nissan Z Performance (Akebono brake) application, not specifically the larger-brake Z NISMO application. One major retailer explicitly states their DBA 5000 two-piece rotor is for the Performance model with Akebono calipers. (TFworks)

That distinction matters because:

2024 Z Performance
  • Front rotor: 355 mm
  • Akebono 4-piston front caliper
2024 Z NISMO
  • Front rotor: 380 mm
  • Larger Akebono front caliper package
  • Different rotor dimensions
The NISMO front brakes are effectively an upsized system.

Important Finding
I am not currently finding a DBA catalog listing that explicitly confirms a 380 mm Z NISMO-specific DBA 5000 front rotor.

What I am finding:

  • DBA 5000 for 2023+ Nissan Z Performance (TFworks)
  • DBA 5000 for 370Z NISMO/Sport applications (KamiSpeed.com)
But those do not automatically confirm fitment for the 2024 Z NISMO's larger front brakes.

This Changes My Recommendation
If I were updating your locked Stage 2 today, I would no longer state:

"DBA 5000/T2 rotors are locked."
Instead I would state:

Stage 2 Rotor Package
Pending final confirmation of Z NISMO-specific fitment and availability.

Current leading candidates:

  1. RacingBrake two-piece rotors
    • Specifically confirmed by owners on the 2024 Z NISMO
    • Direct bolt-on
    • Designed around the 380 mm NISMO system (nissanzclub.com)
  2. DBA
    • Only if a NISMO-specific 380 mm application can be verified
My Recommendation
Given your GT-R experience with drilled rotors and your desire for:

  • repeated highway pulls
  • thermal stability
  • durability
  • OEM+ engineering
I would now lean toward RacingBrake two-piece rotors for the NISMO unless a DBA 380 mm NISMO-specific rotor is confirmed.

The good news is your other Stage 2 items remain exactly as locked:

  • Ferodo DS2500 pads
  • Stainless brake lines
  • Motul RBF600 fluid
  • Motul Multi ATF transmission fluid
The only item I would currently place an asterisk beside is the rotor selection until NISMO-specific DBA fitment is confirmed.
