A little update on the car...

This Sunday I will be picking the car up from Berk Technology after the cat-back exhaust development. When I pick it up, the car will have the stock exhaust back on it and Berk will get to work making a production version for me to test. Once I get back to Vegas I will do another baseline with the stock cat-back since I never dynoed with the JWT pop-chargers and the temperature here has gone up 40 degrees since my last dyno. So this way I will have a good baseline before installing the Berk Cat-Back. Once its installed its off to the dyno again to see the gains.

After I pick up the car at Berk on Sunday, I am going to hang around SoCal Monday and hit up a few other manufacturers before heading back to Vegas that night. My first stop on Monday will be BRIDE seats. They have gotten a set of 370Z rails in for Japan to verify fitment on a US 370Z so I will swing by there to test fit them real quick. If they fit, a whole batch of them will be ordered! Unfortunately I will not be buying a set of BRIDE seats for my car right away due to budget restraints. My second stop will be to Forgestar wheels for some measurements to see if a 19x10 and 18x10 rim will fit up front, and also to double check 18" clearance over the sport package brakes.

I will get the car back to Vegas Monday night and starting Tuesday the thrashing will begin to prepare the car for the upcoming time attack! Here's the punch list for the next 2 weeks.

- New baseline dyno
- Install Berk Cat-Back Exhaust
- Dyno test Berk Cat-Back Exhaust
- Finally get around to making a mounting bracket kit for the Mishimoto Oil Cooler
- Re-Install Mishimoto Oil Cooler and change oil.
- Install Carbonetic 1.5 Way Carbon Limited Slip Differential
- Break in Carbonetic 1.5 Way Carbon Limited Slip Differential and change diff oil.
- Install Nismo 60mm Wheel Studs
- Get Nitto NT05 tires mounted on a second set of 19" Forgestar F14 wheels. 19x9/19x10 - Piano black w/neon stripe
- Re-Install Hawk HP+ brake pads
- Get cracked windshield replaced
- Re-check alignment and corner weights
- Wash/Wax
- Get "time attack" vinyl layout installed.

Have you had a chance to see if 19X10 will fit up front? Ideal sizing would be 19X10 up front with 19X11 out back IMO:tup: this would keep the factory stagger proportional...

DD,

I'm looking at Nitto Invo's for my next tire. How have they treated you both on the track and street?

I just went to Forgestar today and they measured and it looks like a 10" will fit up front!

Thanks Mike,

What's the chance of rubbing when fully loaded at the track (especially if slightly lowered on coilovers), or is this more of a show setup?

So I take it the fitment over the calipers was ok?

The Invo's are a great street tire, very quiet. They are not a track tire though. I have not tried them on the track, nor do I plan to. The NT05 are a much better compromise between street & track.

If you ever take the NT05's out on the street, feel free to PM me. I would like a tire that grips well both wet and dry, and is quiet.

To be honest I have no clue about rubbing at the track. The answer to that is just going to be figured out by trial and error hahaha. I think it should be fine though. Most of the extra inch will be added to the inside of the wheel, not the outside.

Fitment over the calipers was fine.

A little trial and error is fine as long as I can correct it :p

So now I just need to decide if 11 or 12" is the way to go in the rear.

11" is the way to go in my opinion. 12" is too big for anything practical. Even if it fit you couldn't fit a wide enough tire up front to match how big you would have to go in the rear. There would be too much stagger IMO. I personally am going to go with a 275 front 285 rear which I think will be a great setup for the track on the 370Z. I simply don't think the car has enough power or speed to warrant a bigger tire setup than that. There is such a thing as having too much tire.

Yeah, that sounds too small to me too... Hopefully won't look 'stretched'! Seems like anything from 295-305 would be ideal. Makes sense that 315 would just be adding weight for an NA 370z.
