Here is my Z. I am in love with this unit. I’ve owned it new since April 2023. Canadian season is so short but have been able to put ~ 30,000km on it so far.

Beautiful build and car
Love the wheels, been my top choice.

How are the hipermax S?

 

[SoupZ]

They have been great. I installed them at the preset height and set the dampening to mid (15 or 16 I think) and haven’t had any issues. They are stiffer than stock but by no means unbearable to any degree. A great amount of stiffness and lowering

I am rubbing through my fender liners in the front but that’s a crappy Canadian road problem more than anything.

Awesome, glad to hear the positive experience.

I'd recommend an intake on your beauty, will bring some good notes for that NISMO exhaust!

 

[Mellowyellow]

Beautiful build. You opened up the intake and exhaust. Did you also have it tuned?

 

[SoupZ]

@Mellowyellow not yet. I would like to get a SonicTuned tune. Hoping to do it next but the season here is almost over so I might wait until next year.

You might want to check with SonicTuned about running intakes, ldp's and bigger exhaust without a tune. I could be wrong but it seems that I read that could be hard on your turbos.

Please feel free to correct me if there's info from pro's out there I've missed, and if you disagree with my assessments. Open debate typically works toward the common good.

What I'm gathering right now, going back to the Q50/Q60, is the Pro's "recommend" a tune if you change LDPs, especially if you're running a really free-flowing intake and larger exhaust. Reactions range from 'I've been running mine for thousands of miles without a tune' to 'I blew my engine.'

Based on what I know about turbocharged engines, opening up the intake and exhaust without taking other steps to control air/fuel more effectively can cause overboost and a lean condition. Neither of which are good for long-term engine health. Getting thrown into limp mode shows you there are issues that need to be addressed, but the lack of limp mode doesn't mean everything's good. The engine could be running right on the edge of limp mode constantly, making you think all's Kosher, meanwhile you could be constantly running lean and hot just below threshold, and slowly damaging bearings and other stuff.

MY OPINIONS, based on my average level of experience and slightly above average level of constantly researching and learning crap that interests me but does me no good in my daily life:
- Intake...No tune
- Cat-back...No tune
- Intake and cat-back...No tune if exhaust is smaller than 2.75" - Maybe, if 2.75" or larger
- High-flow catted LDP with stock intake/exhaust...Probably should tune
- High-flow catted LDP with intake and/or exhaust...Tune
- Open LDP...Tune

...I installed them at the preset height...

I realize you said this, but because the Hipermax S is in my top 3 right now, I want to confirm,
You installed them without loosening a collar or changing anything at all, correct?

 

[SoupZ]

@FSUZ33 Correct. I didn’t adjust the the height or preload or anything. Just made sure collars were locked in. Only adjustments I made was the dampening to mid to ensure it was in fact at mid.

I would say this is very consistent with the overall groups knowledge. If you change "air flow" in or out... Keep in mind you, you might need a tune.... "I've been running mine for thousands of miles without a tune' to 'I blew my engine." Lol Sounds bout right
