Nismo vs Sport ?

MaysEffect

This is very much dependent on tires and tire size. The Nismo suspension in most cases will and can handle stickier tires better. For normal tires it may actually make it feel worse like you said.

I run Michelin super sport tires, these are mid level race grade tires before going to compound that is so soft you get less then 2000 km to a set.

To put it in perspective, the tires I run are the same tires that Porsche puts on the GT4 race cars out of the box. They are very sticky

I'll have to disagree* earnestly. The PSS are not even remotely the same as cup 2's or even extreme tires for that matter. They lack the tread block rigidity and overall sidewall support as tires of race compounds. They may be good, but they are not comparable to Cup 2's or something in the Extreme category such as the ZII's, BF rivals or RE71's.

They are not race grade tires. Extremes can handle more than 10k miles on and off the track certainly with a uprated sizes. I was able to get over 15k miles on my RS3's on my heavier G37 and over 20k miles on my Direzza ZIIs on my VW R32, and that was even on a undersized tire for the weight of the car and significant abuse on and off the track. Both of these tires can out handle PSS's as well as last just as long with better heat control.

I don't know what size tire you use, but i assure you they do not stack up to the latest offerings in the extreme class of tires. And yes, i have used the PSS on my car before. On the R32, and the ZII's and BF rivals out handled them immensely.

I don't know what it is your debating with me here lol?

I indicated in my post they are mid level race rated tires. Your comparing my tires to extreme track use tires. I completely agree with you that any track rated tire will our perform a PSS.

I never stated any wear that the PSS were hard core track ready tires, I compared them to being decent enough to be considered by Porsche as the tire they send there gt4 race spec cars off the lot on that can handle street and track use.

I think this is the confusion. The GT4 uses cup2 tires, atleast here where i live. If the GT4 where you live comes with PSS, then i feel sorry for whoever buys it there lol. So it sounded like you were saying the pss tires is as good as the cup2 tires. And the other part about them being "mid level" race grade tires, which they are not, for whatever that means. They are very good street tires.

My original point was about how the nismo suspension can handle tires with higher traction limits. Such as an extreme or competition tires.

That's debatable. Other than opinion, I haven't seen much data that supports the Nismo as a better handler/posts better track times. They're about equal for the most part. Yes the Nismo is firmer sprung, but that doesn't equate to better handling. Suspension aside, the Nismo does have additional chassis bracing which will help the car feel more solid.

I'm not sure you read what i said correctly.

The body bracing allows it to endure more track time than the sport, it is more protected from body flex and has better Aero. It has 18HP to compensate for the 88lb deficit.

Other than a little bit of extra help in the endurance dept. And some dampers. They're the same car. They sell a nismo body brace kit for for the sport. I think it's $1,800. Don't quote me on price. I'm sure that'll make them equal.

The Z sport has big enough wheels for track duty, the nismo is a Lil extra for the cars size. PS4's are probably too much for the capability of either car. Those are designed for these 500+HP cars.

Jus sayin.
