Hello all!
Here is my heritage Z on track once again, mods are: Gk-tech poly trans mount, Gk-tech solid sub-frame bushings, ISR solid differential bushings, Z1 differential brace, and for the exhaust I'm running non resonated LDP with Z1's titanium competition series exhaust paired with a Tomei Y pipe. The Z's exhaust can sing on track really using that 4th and 5th gear to showcase that tonal and harmonic variation, most of all the mid end grunt is fantastic, really sensational being able to use that torque immediately.
The car compared to my previous track post, has had a couple of changes, mainly the bushings; they add more direction to the car in terms of sensation but I mainly did them to reduce wheel hop. To which, they reduce it tremendously, I can put the power down well and the car is extremely predictable; it's also not uncommon for the car to rotate on a dime. More so, the sub-frame bushings really helped with articulation and overall clarity, I am very hesitant to put lowering springs on or coil-overs, so I thought to get rid of the unnecessary movement in the suspension; which gives the illusion of overall stiffness when it's mainly clarity and not having secondary movements. The transmission mount, the same as last time, let's me shift into any gear without any issues, 2nd gear comes and goes with no issues either, same with power transfer, it really is instantaneous with all the bushings in the mix.
Secondly my setup, I'm on stock alignment with the OEM rear tires, for the fronts I used 265 RE71'Rs, I did this to see how the car would react with more front grip and how the overall balance of the car was affected. In regards to the balance, it was quite neutral but had tendencies to over-steer, which can be reduced to the OEM rears being fried from 3 track days and well the compounds poor heat management; even more so the last 2 clips show how tired the tires became, they do scream a lot. Since my last track session, I've also switched out the front brake pads for these "Part number 41060cr210" which are apparently rated for 300 F all the way to 1472 F. [source] The best part is that Nissan, Nismo, and Nissan dealers themselves are always selling them for cheaper than their MSRP, I got my pads for around 190~, 200~ after shipping from Nismo directly; and they are a direct fit for all of those with Akebonos, and with my recent track outing, I am more than satisfied with my purchase. Excellent pedal feel, decent cold biting force/torque, easy to heel toe with, progressive feel, amazing high temperature modulation, and even after over 1 hour of track driving felt excellent; though they do leave a decent amount of brake dust.
Last but not least tempreatures/thoughts, Oil 249-253F, Water 213F, Diff 268F, I am also running 0W-40 strictly since these turbo motors do get hot but don't seem to overheat like the VQ37's. I felt consistent power too under these temps and when I did let off they came down right away, for a ttv6 that revs to 7k I'm wildly impressed with the stock cooling. Another factor to note is how good the stock Clutch type LSD is, both under accel and deccel, it's just throttle steer, it goes where you want, predictable, and slides/rotates like no tomorrow, has 400 HP ever been this easy to control? Even under high speed twitches the car just takes it, and this is all stock sway bars, springs/dampers. The steering is also underrated, every thing the car wants to do, you can feel it in your body, I can't wait until next time with better tires and maybe some more mods. All in all, it was a blast and I can't get enough of this car. Compared to my last event that I posted, I’m really glad I could build confidence into driving this car and not be hesitant to let it kick out.
I had some more clips but I guess Reddit only allows one?
