Thanks,

Basically when I tracked the car I found that the stock LSD was crap. I am looking for a 1.5 way LSD. Possibly an LSD cooler too, but we will see.

Yeah the ratio on the stock unit is lousy, not suitable for anything more than spirited street driving. It's far too easy to spin an inside wheel.

Mike, as you move forward, please share all your research and decision process on the LSD. Thanks. Travis

So back to the diff...

So after taking into consideration everything from price to personal experience, I have placed an order for a Carbonetic 1.5 way carbon LSD. Here are my reasons behind my decision, most of which probably wont apply to most people...

- Track support. Carbonetic usually has at least one representative at all of the major time attacks I go to.

- Dealer status. I was able to meet the buy-in requirements to become a Carbonetic dealer.

- Personal experience. This was the biggest deciding factor. I have run this same diff in my time attack 350Z for the past few years and have no complaints with it. It has held up to much more abuse in my 350Z than I will throw at it with the 370Z and preformed flawlessly. It is actually pretty streetable too as the engagement of the carbon clutches is smoother than that of a metallic clutch.

The close runner up was the OS Giken unit. I have heard excellent things about this unit, I am already an OS Giken dealer, and my dealer price was the same as the Carbonetic unit. The personal experience is what swayed me over to Carbonetic.

So it is on order, but I am not sure if I can get it installed and broken in before the next time attack in a few weeks.

Very nice! It should last longer than the metal unit as well. I'm a little scared to ask how much this unit is going to cost me. I'm adding this to my list, but first I need the basics like heavy duty oil cooler and working brakes.

Price from me is $1425.

Not bad at all.

Any brake upgrades in the plans? I'm actually surprised that you haven't experienced any of the braking problems that RCZ and myself were getting. The bite from the HP+ was good but the rotors seem to overheat and turn to butter.

You guys brake too much

.

No, I didn't experience that at Buttonwillow, but every track is different. Buttonwillow isn't too hard on brakes. Neither is Willow Springs, so hopefully I wont have any issues there either.

Man you guys are like my favorite Guinea pigs

thanks DDM

M.Bonanni · 05-13-2009, 11:25 AM

Ok, the Carbonetic LSD will be installed and broken in before the time attack at the end of the month so I will be able to give everyone some track feedback very soon!

shabarivas · 05-13-2009, 12:28 PM

excellent! what would be awesome is a cam from inside the car - one w/ the LSD and one before

but it might be too late for that... just watch out for the vivid colors and crazy patterns everywherE!!!

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.
