How are you getting so much camber? I am only at -2.5 with heavily offset bushings in the UCA's?

 

KV coilovers offer a bit more adjustability without the use of UCAs. They also put the front end down quite far, so fender clearance may be an issue.

 

What do you guys thnk about the wheel sizes?
I would really prefer to get 9.5's all around so I could rotate them.

I'm running 17's with 275's right now but my tires are done.
I need to figure out what wheels to get then tires.
I really don't want to get tires now just to switch wheels later...

 

You need to read the rules again. You can't use 9.5" wheels up front, max width is 9.0" for the fronts. And if you use 9.5" rears, you're giving up some contact patch, because the rules allow a max of 10.0" in rear width. The spec BFG tire is a 275-35-18, so start looking at 18 X 9.0 fronts and 18 X 10.0 rear wheels for maximum performance.

 

I'm aware of that. My point was wouldn't 9.5 all around be better?
I really didn't want to run staggered wheel set...hence my post

 

Yep, the Wheel rule is ridicules ...but it is the rules. So I am purchasing Enkei RPF1 18x10 +38 for the rear, and 18x9 ET35 for the front. However Enkei is out of stock till June on the 18x9s...which sux for me big time. However they do have 18x8.5 ET30 in stock...and other options my Dealer gave me;

RP03 18x9 +18 20.60lb
RP03 18x10 +22 22.25lb

GTC01 18x9 +18 22.75lb each
GTC01 18x10 +10 +22 24.25lb each

 

I'd wait for the 9's.

 

Yep...I may have to "borrow" some front wheels for my 1st Spec Z race June 15th @ Road Atlanta

 

Nope- can't agree, the wheel rule mirrors what we've been running in SCCA T2 for years. Beyond that, bitchin' about the rules doesn't serve any purpose, particularly when asking for advice.

As for your wheel dealer, have them check the Enkei PF01 model, 18 X 9.0 ET35 for the front. A very nice MATS technology alloy wheel with curved spokes for more caliper clearance than the RPF1 and they were available last time I checked.

 

With all due respect, I can't agree with your statement (bitchin' about the rules doesn't serve any purpose)

I (and others) am working via the proper channels in NASA to request rule changes in several areas...the wheels size and weight is just one.

I have not found a NASA racers that thinks using SCCA rules is the proper way to start a new class in NASA. Spec Miata is a successful class for sure...but that is somewhat a different story.

However I do understand why Nissan is sponsoring SpecZ in NASA, and that is in large part to bring over disenfranchised SCCA 350Z T2/T3 racers. But continuing legacy rules like these will not build additional grass roots racers in the NASA world long term. It will bring a few SCCA folks over for sure, but will they create critical mass for the long term???

And let me be very clear, we welcome racers from anywhere to run with the NASA Family...and this thread is for a healthy discussion of the new class and how to improve Spec Z and the cars that run in it. So please be open to the NASA racing environment...which is very different than SCCA based on all the feedback I have received.

and Thnx for the wheel advice

 

With all due respect, I understand that working through the proper channels with either SCCA or NASA is the right way to go about in bringing change. Lord knows I tried with the former and have hopes for the latter. My only point is that what you label as "legacy rules" are a logical starting place; particularly in the first year. And you can bet I'll be active in stating the case for rule changes (or not) as the class develops.

As for the wheel advice- you're welcome. I'm happy to be part of the Spec Z community and will do my best to be a positive force within it.

 

My car looks silly for the first race. 18x9 OEM NISMO wheels up front, silver 18x10 RPF1s in the back. At least I'll be on the learning curve. . that is, after re-installing the helper springs.

 

@dkmura...our conversation lead to me sending an email to NASA Spec Z National Leadership requesting status on ANY POSSIBLE rule changes.

Will it change anything?

I don't know, but surely hope NASA leadership have at least reviewed the "suggestions" of racers and made an educated decision on a possible direction change.

As a backup plan I will continue to source blower motors/heater cores, misc. interior plastic pieces, and some ugly mis-matched front 18x9 Maximum sized front wheels, and OEM front upper control arms

dkmura...I look forward to meeting/racing with you one day

 

I don't thnk I was bitching. This class is still somewhat in the design phase and now is the time to discuss stuff like this. I think I'm not alone in this particular question. I brought it up on the NASA forum as well. I'm excited about the class and hope it is very successful. The fact of the matter is its success is up to the drivers and drivers should speak up if they see something that could help the class...

 

100% agree, this is the time to speak up,

 

laze,
When is your first SpecZ race?

 

I couldn't agree more. Let's put it another way: rules are rules and in my view let's roll out the ***** and play (or race)! We can debate whether Spec Z is beyond the "design phase" with regard to rules, and provide our input, but there's no telling when or if the update will appear.

With NASA races coming up around the country, it's time to stop talkin' and start racin'. So I'll look forward to meeting and racing with you at M-O this fall. My entry is already in!

 

Would that be Mid-O in September for the National event? I'm hoping to make the trek for it, as I'm not convinced I'll see many more Spec Zs out here for this weekend's event, nor the approximately-one-per-month events in the upcoming months.

 

Hey to you So. Cal T2/3 guys, whats a good T2/3 Z lap around Autoclub Speedway, Roval? I'm assuming 53-54'ish for T2 and 55-57'ish T3. Also assuming SZ (Spec Z) will be in the 53'ish range.

 

We squeezed 2.6L / 2.9R in the front, and 2.1 in the rear. I think I'd like to adjust the toe, though, as I'm at -0.03 / -0.05 front and 0.13 / 0.12 rear right now. Anyone else, thoughts?
