1/3 tank. Seemed light to me also so I'm going to re-weigh it at the track as well. I'm taking out the helper springs now so I'll have to corner balance again anyway.

 

Taking a shot in the dark here....maybe removing the floor pan and welding in a custom one for whatever reason. I know on old muscle cars they would rust or rot out and have to be replaced and you had to cut them out and weld in another.

I really have no idea. Technically everything around you is a "driver compartment panel".

Good luck!

 

You are correct...it is everything else not listed...i.e., the "Metals panels in the car"...and they don't want to remove this wording

I was asking what this was because of the guys that have removed the speaker box and other materials...and since I have my speaker box metal still installed, I am NOT gonna push it.

However, If some wants more info I WILL PURSUE IT!!!

 

I think it will help make it easier for us to hit that 3100lb comp weight if we are able to remove that speaker box metal. Being able to remove the heater core and blower unit stuff helps now though.

Depending on how much fuel you burn in a race I know as it stands right now, I can hit 3100lbs probably around just under a 1/2 tank. Not sure if I topped off the car before a race if I would be above that when I come off track. My car has a few more things removed though that I need to put back on.

 

Since weight is such a big issue, is running a swirl/surge tank legal? That would allow you to run lower fuel and not starve.

Any thoughts about what I mentioned about bushings up above?

 

I would have to check the rules again about fuel cells.

About the bushings, I believe the transverse arm is the compression arm.

I already have some Whiteline bushings in my car, so it would suck to have to take them out and replace with OEM or Nismo.

Because Nissan is involved though, they are going to want us to use their stuff unfortunately. I would not be opposed to running Whiteline or having the ability to run either or. They are relatively inexpensive compared to running spherical joints, too.

What other two bushings are prone to failure?

 

Suspension 101 post #2, transverse arm is the lower control arm, not the compression arm.

the compression arm and the rear diff bushing. Compression arm bushing you can buy from Nissan, but the diff bushing you have to replace the subframe.n

 

I have a full-containment seat, and was timed at like 2.5s getting out of the car. NASA tech DID ask for and check my kill switch. I was under the impression it was required for NASA (but not for SCCA Touring). We mounted mine on the driver's left, on the "inside" of where the OEM side mirror is so that safety crews could access it easily as well as myself.

10s or less is actually what was required when I went through tech. I did read awhile back that the G-force harnesses can stretch a bit more than the higher-cost ones, so that's something to keep in mind. I do realize, of course, that they pass the SFI requirement, and SCCA allows the belts for one year longer than NASA. Also note that most of the budget restraints have 3" shoulder belts, which work but are not the most comfortable when wearing a H&N restraint. I didn't realize how much nicer/more comfortable the 2' shoulder straps were until I got a set; they are MUCH easier to navigate than their 3" counterparts.

2855 without driver and spec-legal? Wow! I'm still 60-80# heavy, but will lose some of that with changing wheels and exhaust. Any reason for the 0.4 delta in rear camber? I also think you are going to want much more front camber - whatever you can squeeze out of it. I started full soft F/R sway bars, and adjusted from there. Are you on the spec tire?

I have two you could borrow, if you're game for that expensive proposition. . .

That would be great, since I'm seeing some fuel starve with 5 or 6 gallons remaining after a high-speed/G right turn (T-hill T15)

 

I do remember the diff bushing. I was going to get Whiteline ones, but they are not legal for Spec Z. Like you mentioned, it would be nice to be able to use those.

 

Thanks. Those are some good drawings.

 

I'm kind of surprised they didnt just go with whiteline...if you look at the Nissan-Motorsports Catelog they actually list and suggest Whiteline products for various cars. Regardless, it is still a step in the right direction, but the rear diff was definitely an overlook. it is still a young series, so i am sure it will adapt with the trends.

 

Hey guys, I had two questions.

1) As far as I can tell, the only LSD upgrade allowable for spec Z is the wavetrac LSD. Does this mean we arent allowed to use the Nismo LSD even though most other Nismo parts are allowed?

2) I see a lot of people complaining about this new Spec Z class (mostly on other forums) because their modified Zs are modded well above the specs of this class, and they dont want to have to remove them. Can they not still race PT/ST with the 350z now that this class has been created?

Thanks!

 

I believe you are correct on the LSD unless you want to use a stock VLSD.

...and yes those other guys can race in PT. It just depends on their mods where they would end up....most likely PTC, PTB or PTA.

 

Correct, no other classes have been removed or the 350Z excluded, this is just a new place to run that will help keep costs down a bit, and allow all the displaced T2/T3 cars from SCCA have some fun. It will also give the 350Z a place to run up front depending on the driver and the setup vs being the underdog in most other classes.

 

Up front of the SpecZ class - yes, this is certainly possible. Up front of the mixed class they are (currently) having us race in - no way (ST2, SU, ThunderRoadster, GTS3).

 

Umm...if a 350Z isn't upfront in SpecZ, then we have bigger problems.

 

 

So, the Nissan dealer can't get the Dayum Wavetrac into a stock 2007 Open diff...can't get the C-clips in.....F HJJJHJ<NKLHB NBH K~!

Something about the stub axles are "mushroomed"...WTF????

 

What do they mean by "mushroomed"? Have you looked at having the grooves machined to accept the clips like Terrasmak did?

If it looks like it's going to take a while to get the Wavetrac sorted out we can swap the Carbonetics diff back in after I do AMP on the 12th.
