track set up?
 

i know there are a lot of track experts . i hope u guys can help me to figure out something. i have a 2015 nismo. i am planing to build it for track usage. All i want is the best performance in the track. Basically this car is stock weight but i might change the stock exhaust to a tomei single ti exhaust to take some weight out of the car. My questions are what kind of coilover( spring rate) , sway-bar and tire set up should i use ? Answers would be really appreciate.

I am no expert but generally the consensus is the stiffest sway bar you can get upfront. stock or none in the back. Many use Hotchkis or Whiteline. There are many options for tires but square setup is best, 18" will save you money and give more options for tires. AAM short tails and mid pipe will offer the best performance and weight. From stock you must add an oil cooler and upgraded brake pads and fluid. There are many choices on pads, search, I use XP10 front XP8 rear with RBF600. The stock nismo suspension isn't bad but the consensus is KW v3.
Other people can give you better advice in the track section and with more info on your experience level and budget. There are very useful stickies there too.

It sounds like you have a lot of reading to do. The link below is an excellent place to start :tiphat:

Hey Mods! Please merge this thread with his other thread in the track section. ;)

Best mod hands down is seat time.

Assuming you already have good seat time, time to upgrade the brakes and safety systems.

This is a fast car. If you are serious about it being a track car you will want good belts, a HANS, and good safety gear. Cages are always nice.

:iagree: with Read, seat time and safety. And as 2011 Nismo #91 said, brake upgrade and oil cooler too. Then do some suspension changes...
The Z has plenty of power as it is, there's no HP gain needed for the twisty track.
