155 MPH (250 KPH)

Yes, This would be in reference to a factory suspension. Center all the specs on the alignment chart and match from side to side. The car will handle as the Engineers designed it to. This will also produce optimal tire wear and fuel mileage when you're railing the car. I've had this type of alignment done to my factory cars for decades. Run a half to full tank of fuel for ballast. If you go somewhere and the guy tells you, I'll try. He's telling you I don't have enough brains/talent to do the job. When I bought mine new I told the manager I'd bet him a 20 the tires were over inflated and the alignment would suck and most likely not even be in the green. He wouldn't take the bet knowing I was right and I was. I'm coming up on 20k and I'm still not on the tire wear bar but it's getting close. If your showing abnormal tire wear, then yes it's going to suck on the big end ie high speeds. Even though the stealership techs are paid to perform/complete the PDI, more so than not, it aint happening.

147 before I pulled my foot off.

Took my 03 Track (6MT) to the limit, pedaled the throttle and held for about 10 secs. It started to get a little 'floaty' at around 140. It had something they called a "zero lift package" that was supposed to make it safer at higher speeds. May have been on all models, idk. Never figured out if there were parts involved or it was fancy marketing terminology.

My recollection is the 155 mph limit is a safety thing. Not mandated, just a common standard many manufacturers use. Someone told me years ago it was insurance related, but I don't think that's the case.

this is the fastest ive gone in the Z since I drive like a grandma on the street because Im not gonna be caught slippin by the police and I have good insurance rate lol.

this was on track so couldnt have gone much faster as I needed to get down to about 45 mph a few feet ahead or I wouldnt be typing this right now

Thats weird but for me i managed to reach 262 kph or 163 mph im not sure why its not the same as other z's but i aint complaining

I haven't yet installed the underbody plastic parts ( wind diverters ?? 2 in front of wheels, and a longer rounded part? ) I wonder if these help downforce?

Installed on mine the weekend I got it and I don't know if it's a bit more experience than others or what but I have never felt as unsafe as some people here are saying at 130+ mph. So I don't have anything to compare it to as I never went super fast between the time I bought it and installed those but yes those parts will help.

Proper aero kit should fix that I believe.

I just added a lip spoiler and sway bars and felt its very stable. Not sure if its the placebo effect or what.

Did the throttle cut at 163, or was that max speed?

 

[takemorepills]

Tires.

All tires have a max speed rating. Most manufacturers will speed limit a vehicle to what tires will be installed.

If the Z Sport has a lower top speed than Performance, it might be because the tires Nissan installs on the Sport have a lower speed limit. Really no other reason between a Sport and Performance model.

according to nissan its partially because the sport doesnt have the rear spoiler and front under spoiler

Here's a video I found demonstrating Z's top speed limiter.

To be honest im not sure as I couldnt tell at the time. I let go as soon as i felt it had stayed too long on a certain speed and I just assumed that was the limit.

Sway bar effect is definitely not placebo.

That was my video... xD

Since then, I have got it tuned and gone 186MPH - 300KPH...
