SPC is sending me a different part to try next week... I believe the current part, the one that doesn't fit, is a 1-1 match from their G37 part. They want to try the G35 part next... They should be paying me for this !!!

Well I hope the G35 part fits! That would mean that I can get SPL Parts front control arms. :D

So basically what you're saying is that SPC starting selling this part without test fitting it on a 370Z at all? That's pretty bad IMO. Bascially they are now using you as a guinea pig which means they should give you the parts for free.

Not going to comment on exactly what i paid for them, but it def wasn't retail... wasn't free either ! but the labor is starting to pile up !!

SPL Parts has 350Z/G35 arms already so if SPC's G35 arms fit then so should SPLs. :)

Got it, thanks

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...

LiquidZ 05-18-2009 08:02 PM
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!

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.

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?

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.

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.

The NT05 is considered a maximum grip street tire that is trackable. It has solid wet performance but not as good in the wet as the Invo, but is better in the dry. The Invo would be quieter. I know lots of people that run the NT555 as a street tire as well.

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.

Sure thing. I should know the answer to that in a few weeks.

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.

285 on an 11" rim?

Edit..

To bounce back over to this thread, I was looking at (now) 275/35R18 on 10" fronts and 315/30R18 on 11" rear, they're nearly identical in revs per mile. The 285's I saw (on the PS2's I'm looking at) are specced for 9.5-10.5 rims, 10 being the norm. Just seemed odd to me, I'm curious about the rationale behind 285 on the 11 rear.

Slidefox 05-19-2009 12:07 AM
The Z looks great fellas!!

travisjb 05-19-2009 12:19 AM
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. Re 285, guessing Mike is going with what's available through his tire sponsor

BTW, here is the best deal I've been able to find on R888s! If anyone has seen better pricing, SPEAK UP !

Well part of why I liked the PS2 275/35 + 315/30 setup is the revs per mile come out at 815 and 817, which is nearly a perfect match in height/circumference. It's hard to find anything else remotely that close in rpm that matches up well with all the other factors. Even if the extra few mm of rubber weighs a little more, the whole setup is still 10% lighter than the stock 19+RE050A setup.

M.Bonanni 05-19-2009 12:34 AM
No my 285s will be going on a 10" rim.

Actually I would really want a 11.5" but that's not an option. Yes the stagger is a concern, I want to keep the stagger to less than 40mm (30mm would be better). The initial plan is for a 275 front and a 315 rear, but I can get good deals on Hoosier scrubs that might be one size wider.

M.Bonanni 05-19-2009 10:26 AM
I think even 30mm is too much. To dial out some of the factory understeer I would do 10mm-20mm stagger.

Hmmm... yeah the understeer does suck a little I've noticed, and I guess I'd be making that worse with the fat-*** rears I'm looking at. Do you think running aftermarket sways with the rear at the hardest setting would alleviate it enough?

Official update:

I picked the car up from Berk Technology on Sunday with the stock exhaust back on it. The prototype exhaust system looks awesome in person and I cant wait to get a production version on the car for testing. The production version should be on its way to me at the end of this week or early next week with an X or H pipe. Plans are to get another baseline dyno before the Berk exhaust goes on then dyno again after the exhaust.

Yesterday before coming back up to Las Vegas, I stopped by BRIDE seats to test fit new 370Z seat rails. Good news is they fit! Bad news is that they wont get any more in until mid July.

After BRIDE seats, I went to Forgestar Wheels and we measured to see if an 18x10" rim would fit up front and also make sure that the 18" rims will clear the sport package brakes. Forgestar is confident that everything will be just fine!

I will be looking for coilovers than have a stiffer rear spring, maybe as much as 14kg/mm vs a 12kg/mm front. I also will be looking for the stiffest rear sway bar I can find.

I'm still digging on tires sizes too. One way or another I'll make 18x10 and 18x11 work for me though. I really wish the PS2 came in some 305 sizes, it would make fitting this together easier. Another good rev-matched setup I found for the PS2 though would be to go 285/30R18 + 295/30R18. They're a little shorter than the 275/35 + 315/30 setup I was looking at earlier (which is a good thing, imho), but well-matched to each other (840 and 832 revs per mile, with the rear being the slightly taller one). The 285's are rated for 9.5-10.5 rims and the 295 for 10-11 rims, so that would fit on the 10/11 staggered rims and get the tire stagger down to 10mm.

I'll probably keep contemplating this and the rest of the suspension setup while waiting on the forgestars to be made anyways, and change my mind like 5 more times on tires :)

Carbonetic 1.5 way LSD just showed up! It will get installed on Thursday morning.

Excellent, I'm waiting to hear how you like this on the track, and how it holds up under longer/hotter sessions vs the stock VSLD.

Unfortunately Big Willow wont be too hard on the LSD compared to a track like Buttonwillow. Big Willow is big and fast, not many tight corners to power out of. What Big Willow will do though is put the Mishimoto Oil Cooler through the ultimate test since there will be A LOT of full throttle, sustained high RPMs and air temps close to or over 100 degrees.

Exciting stuff going on with your car Mike, Im staying tuned to your results!

I'm loving this car too. Really excited for the Berk parts, and I'm really thinking about getting a pair of BRIDE seats...

Then again, $ comes from WHERE?! :(

M.Bonanni 05-19-2009 04:53 PM

travisjb 05-19-2009 08:45 PM
Sweeeet! Helpful update Mike!... and great news on the rails. I should have mine back this weekend too, with same diff and some other bits... going to update journal now

M.Bonanni 05-21-2009 11:21 AM
So I know I was supposed to have been working on it, but unfortunately I have been really sick the past few days so nothing has been done lol. I was supposed to have the diff installed this morning, but Travis has informed me that some other parts are needed to complete the install so I will have to wait until I get those. Looks like next week will be REALLY busy.

bboypuertoroc 05-21-2009 04:20 PM
Bad DDM. BAD.

LOL

M.Bonanni 05-24-2009 04:51 PM
FINALLY started to work on the Z a bit today. I got the Mishimoto oil cooler kit back on the car and realized that its not quite everything I was hoping for. I will not be making a mounting kit for this oil cooler just because it takes a bit too much work to make it fit well being a universal kit. The first time I mounted the cooler to the car I did a half *** job just to get it on the car for testing. This time I took the time to mount it better and although I have it on my car the way I want it, it just takes too much work to make it fit right for me to offer a proper mounting kit. Its still a great kit for those who don't mind spending the time to make everything fit perfect.

Mishimoto universal oil cooler kit:

Pure Power oil filter mated to Mishimoto sandwich plate.
http://www.doubledownmotorsports.com/370zoilcooler4.jpg

I have also decided to hold off on installing the SPC rear toe bolts just because I don't need them at this point and because installation requires some drilling on the car to make the holes a bit bigger and I just don't want to do that for a part that I don't NEED at this point.

Tomorrow the Nismo wheel studs will go in, the Hawk HP+ brake pads will go back in, and the spare tire/tools/ trunk plastics will come back out.

eXo5 05-24-2009 04:58 PM
I just realized a few days ago the mishimoto guys actually work out of my home town. I havent really seen much of what they have done yet. Im pretty sure theyre a fairly new company. Mayhaps if we can generate some kind of demand for the item they may be interested in making one specificially for the Z?

I spoke to them about that a while ago and they weren't at all enthusiastic about the idea unfortunately. They were more interested in doing a radiator which I am sure will come out soon.
