I would like to introduce you guys to the NASA National Spec Z Director....Clifton Winkleman...aka Waco Racer...

All complaints should be directed his way

I haven't looked yet, did the revised rules get published?

 

no.................

 

I believe this one fulfills the requirement: http://www.ioportracing.com/Merchant...ory_Code=FE-HH

 

I just sent off 4 9" RPF1's to Scott and the weights at Fedex could be a concern. The wheels (which had 255 Dunlop Star Specs on them) only weighed in at 42.6lbs. Tire rack has the 255 star specs listed at 27lbs. The weights for the 9" always seemed a bit heavy compared to the other RPF1's. The star specs were pretty new as well. If they are only 15-16lbs....that could be a problem.

 

Need some advice on safety equip for my spec z build after watching the video of 350z crash at a mid Ohio SCCA event. I was considering the Kirkey full containment or Sparco Pro ADV since both have the large head restraint but I was concerned that I wouldn't be able to get out the drivers side window quickly or it would impede vision on drivers side. ( I'm 5'11" about 185#) Any thoughts? Also should I get the 6 point harness? G Force seems to have a great price for one but it seems to good to be true. A kill switch is recommended in the CCR but is not mandated by our class rules that I could find. If I mount one, any thoughts on best location? Thanks for any input, this thread has been mucho helpful during my build

 

The g-force 6 points are good harnesses. If you can spend a little more, get the Cam latch vs the standard. It will make things much easier.

Yes, you really need a kill switch. Mount it in a place where both you and an EV worker can reach.

On almost any of the full containment seats, egress is easier than you think. The belts and any accessories will slow you down more than the seats will. A good test is to be able to exit the car in 10 seconds or less. You can exit through the door, you don't have to use the window. As far as vision goes, your H&N device will impede your side vision more than the seat will. This why proper mirror set up is so important.

 

Thanks, good to know. Still have a bit of a blind spot on drivers side that I'm trying to fix with my mirror setup. I'm going to post my setup for this weekend and see what you guys think. It's the first time on the track with the spec z stuff.

 

I'm going to PBIR Saturday to try out the new spec z suspension and was wondering what you guys think of my initial settings. Surprisingly the weight came in at 3040 with driver (185#) so if scales are correct I'll need ballast to 3100 for my 2004 z. Left was 51.7%, rear 48.7 % and cross was 50.4% (LR to RF). Hard to jack weight around since the rear is maxed out on the spring to the lowest ride height. Still waiting on rims due to possible rule changes so running my old RE11's on 18 inch LMGT4's. LSD installed as well. Due to my ltd experience (HPDE, karting and Chumpcar) I would prefer to start with a little understeer I think. Critique at will, I'm thick skinned.

Sways=full stiff front, mid rear. Dampers= initial rec's per the KW instruct manual
Toe=1/16 out front, 0 rear. Caster +8.4 LF, +8.2 RF
Camber= -1.7 LF, -1.5 RF ( any suggestions to get more?)
-2.5 LR, -2.1RR

 

Wow 3040 with driver! That's nice. Do you have any pics of your car and how gutted it is? Mine is pretty stripped down, in fact more than Spez Z will allow and I'm around 3090 at 3/4 tank of fuel. How much fuel was in the car, because fuel is heavy.

Well Scott will be happy...I just sent him 4 9" RPF1's.

 

WooHaaaa!!!!

Dayum you guys are Good!!!!


I like, I like!

not changed ??? Heater core may be bypassed, but not removed or modified in any way. The rubber hoses that
supply water to the heater core may be shortened or eliminated.

deleted: If spacers are used they shall be no greater than 13mm and equal per axle.

added: Minimum vehicle weights (listed in pounds) are the result of research based on the weights of Spec Z legal race cars. Potential power – to – weight ratio largely determines the minimum weight for any given
vehicle. Other factors include brakes, torque, and wheelbase. Vehicle weights will be taken, as driven or
raced, post qualifying or race, with driver.
Note: Since this is a new series vehicle weights may be adjusted to equalize fairness in class. Notice
will be given no less than 10 days prior to an event.

added: The kits must be used in their entirety with exception of helper springs. The helper springs that come with the suspension
kit may be omitted during installation.

added: No wheel permitted for competition use can weigh less than eighteen point five (18.50) pounds with the exception of the Enkei RPF1 being specifically permitted for competition use

added: Any Model Nissan 350Z is eligible for competition in the Spec Z series. Any model 350Z may
compete as delivered from the factory. Additional components that were provided on the factory
Nismo version of the 350Z may be added to any other model of 350Z excluding engine components.
This includes brake components and exterior body panels.

added: Nissan Motorsports front brake cooling kit part # may be utilized

added: g) The air conditioning system may be removed. Modification or removal of the heater core and
blower fan assembly is permitted, but not recommended.

added: NISMO Hard Rubber Suspension Bushings
Part No Description Needed per car
54541-RRZ30 Front upper A arm bushing 4
54560-RRZ30 Front lower transverse link bushing 2
55045-RRZ30 Rear upper A arm bushing 4
55148-RRZ30 Rear radius rod (toe link) at hub bushing 2
55149-RRZ30 Rear radius rod (toe link) at body bushing 2
55152-RRZ30 Rear lower link (camber link) at hub bushing 2
55153-RRZ30 Rear lower link (camber link) at body bushing 2
55158-RRZ30 Rear lower control arm (spring arm) bushing 2
56218-RRZ30 Rear upper shock absorber bushing 2

 

I see conflicting wording:

11.3.3 Heater Core
a) Heater core may be bypassed, but not removed or modified in any way. The rubber hoses that supply water to the heater core may be shortened or eliminated

vs

18.2 Interior
g) The air conditioning system may be removed. Modification or removal of the heater core and blower fan assembly is permitted, but not recommended.

Looks like NASA failed to remove or modify section 11.3.3...

After everybody comment , I will get with NASA Leadership...

 

Fixed

I noticed that, too. I was bummed initially, then I made it down to the lower sections and got excited again...

That's good news for me

 

Useless, out of the 3 bushing that are know to fail, only one was addressed with this. That is what happens when Nissan is involved. So they expect you to buy a new subframe everytime that bushing fails. Transverse arm, is that the LCA or compression arm, either way the other arm needs to be addressed.

Whiteline would be a great solution to those two bushings.

 

Damn I can get wheels now!
I was thinking 9's all around......

 

Yep, I purchased 4x RPF1s in 18x10 ET 38...still waiting on the 18x9 ET35 wheels to get here on the dayum boat from Japan...Enkei is out of everything that works for this class now...

Anybody want to sell me 2x 18x9 RPF1 ET 35 in silver?

Also, since they dropped the spacer size rule, it helps finding wheels that fit or could be used in a Square setup...

 

I am also asking for this to be removed...

k) Removal; or substitution of driver compartment panels is not permitted.


WTF does this mean??
