Good question. I wonder if the new SCCA rulebook is out for this year. I'll have to go research this.

I'm assuming of course that you want to know the "stock" class of the FRS right?

There's no classification yet as the car isn't out yet. The SCCA will have to study the car's results and come to a decision for next year. So the BRZ/FRS will only be able to compete at the regional level. It won't be eligible for points on the national level.

But compared to similar cars, it looks like C Stock and STX.

[Sccabrz192]

Thats not necessarily true. As long as the car meets production quantity requirements for this year (which it should/will) the SCCA SEB will class it via fasttrack at some point this season for national competition. I can attest this vehicle launch is being viewed as a very important vehicle to class in terms of future growth for the sport, so i wouldnt be concerned about them burrying it as an also-ran. I support their decision to continue on holding off classing it until they atleast have a few points of reference this summer.

Interesting thread. I'm surprised how many of them are taking a magazine's numbers as gospel. As active AutoXers, I'd think they'd know how much a driver's abilities can influence such numbers.

I still believe it'll be CS and STX. It's too risky to start it in DS because it might dominate. And it doesn't seem to have the oomph to compete in BS. So I'm sure it'll start in CS.

[Sccabrz192]

It's been a long winter of speculation/bench racing... much of it assumes common driver capabilities.

I am not typically one for bench racing, every vehicle has its shortcomings and its challenges and most are not so evident just based on 0-60 times, skid pad G ratings, and spec sheets. I've placed my bets, put my money down. I won't be driving my BRZ this year, but I think it can be a winner regardless the class... some just may be a little more difficult. The SEB will make the necessary shifts as data pours in to make sure it at least has a fighting shot in the long run and isn't an overdog. They know this isn't "just another car" to squeeze in, it represents hopefully a flurry of potential new members to the sport and hopefully a shift back to the old sports car mentality from manufacturers.

IMO current E-stock cars have had their hay-day. They are becoming quite difficult to find in an order which is consistent with the stock rules and are in good working order. Not to mention they have other places to play and win (Read: STS, CSP). CS also-rans are now quite inexpensive and should be moved down, and CS/ES can start accepting new coupes/convertibles based on their capabilities rather than a price tag.

I'll be AutoXing it this year. I compete in RallyX, so I just AutoX for fun. I don't care what class they put me in. I usually AutoX my STI, but I'm looking forward to the BRZ as a training tool. I've been relying on the power of my cars and "saving" a fast entry as ways to be fast. I need to work on being smoother and a momentum car like this is a good place to start. I've thought of picking up a Miata for training, but I haven't been able to justify fitting it into my stable. The BRZ will work as a DD for me as well.

[MarkRacerX]

Def Pumped to Autocross it! Be whole new experience coming from a few STi's w/ awd mad understeer...but I did Autocross my 350Z and 135i which had no lsd .

One way to learn a cars limits, RACE IT !!!

[Sccabrz192]

You will quickly learn what momentum is and why brakes are the enemy.

I'm thinking CS and seems to be the general consensus. Regardless it's going to be a blast through the cones. I autocross a FF in CM and will take my BRZ out occasionally or when it rains. It's going to be interesting to see how it stacks up against an RX-8.

[Sccabrz192]

Sounds like Either a proposal or decision was made at this months meeting. Look for info in the next fastrack! "Someone" seems to think we should like the results!

Quoting from the other thread:

Looks like Fastracks usually come out on ~20th, so not too long to wait for official word, correct?

...and the 370Z's!

I hadn't heard or thought of this, but it does sound like a good approach.

So if this goes through, the 86's would run in CS this year 'as is' with the changes implemented for 2013, correct?

[Sccabrz192]

Junior Johnson fished for peoples opinions on his facebook page before the meeting. That was probably the most useful and informative source ive seen with some good sound logical opinions. Yea still not sure what the outcome will be, usually they wont bump cars around to new classes until the offseason. I dont think ive ever seen it done mid season. that would be unfair to current competitors. I should also clarify the MSR and ZOK models are the ones being scrutinized because of their upgraded oe suspension packages. Id assume if speculations on what the sti brz will be are true, that would go with the zok/msr packages.
Your assumption sounds valid to me as far as timing and process.

Letter number #7596 is currently waiting to be reviewed by the Street Touring committee. After the Street Touring committee reviews your letter, the SEB will review it, and it will proceed to Fastrack.

this was a couple of minutes ago..

[Sccabrz192]

I was speaking strictly of stock class, there are different committees for the different class structures. Though it seems to be a foregone conclusion the car will be stx with the new st structure. Stock is a little more difficult to class.

Regardless, i assume your petition was for stx?

I know... just giving ya something to think about.. and it is...STX...makes the most sense...even used a RX8 as comparison

Has anyone found a stock class eligible, lightweight, aftermarket wheel with the proper offset? No one seems to make one in 17x7 5x100 15-17lbs. Everything I'm seeing is at minimum 17x7.5 which is illegal. Stock wheels are roughly 20lbs, not bad but definitely could be better. Any suggestions?

lots of them.... stock offset 48...you are allowed plus or minus or a 1/4in..which is about 5mm according to stock rules... particular Brands are Enkei and Kosei.... 17x7... 48 all day...

All Day?? I see one wheel on that page that is stock class legal and light weight (<17 lbs)

I've been looking too, and you're right, there are surprisingly few options. I would REALLY like an RPF1. Enkei makes a 17x7 in the proper offset, but its 4x100. And no, they can't just drill blanks to 5x100. That would require a large batch...

The stock class rules allow +/- 0.25 in (6.35mm) in offset. So any offset between 42 and 54 is legal. Spacers can be used to acheive maximum offset allowance. Given the relatively tight inboard clearance to the front strut and the fact that you'll want to stuff as much tire as possible in there, I'm thinking that shooting for a 42-43mm offset is probably a good idea.

There are a couple options that I've found:

-Kosei K4R (on the TireRack link above): Cheap and light. 14 lbs. 50mm offset (with a 5mm spacer?)

-Buddy Club P1 Racing SF: Still on the cheap side, but not as light (maybe 17.4 lbs?)

-Team Dynamics Pro Race 1.2: These won't be in stock anywhere in the right size, but TD will custom make individual orders to your specs with a 6-8 week lead time. They're reasonable priced, and 17.3 lbs.

Hope that helps!

wow...Dude...

maybe not under 17lbs unless your wanting to spend some serious Coin..the Kosei are 50 offset...I would say that is about perfect...why would you want to put a spacer on it??? even with a 5mm spacer you sitting at 45 offset...well within the Stock Tolerance...

There is plenty of wheels 17x7 in a 48 that go way lighter depending on how much coin you want to throw at it... Volk, SSR, Work, 949 racing, CCW, FISKE, OZ, SPARCO,...Hell you can get RPF-1's in a 17x7...or...god forbid...Rota's... they all have options with-in the spectrum of what you can use for stock class... He asked for options...I merely was giving them

I think you misread my tone Bill.

The reason a spacer may be needed on the Kosei rims is because the inboard clearance between the wheel/tire and the strut is relatively tight. I was suggesting that maximizing the offset allowance, as opposed to moving further inboard with a 50 mm offset, would allow for bigger tires.

I see a lots of brand names in your post, but I'd be really interested to see a specific wheel from any of the companies you've listed. I'm genuinely curious.

[Sccabrz192]

Enkei, Oz, and sparco (made by oz) dont sell 17x7 with 5x100 currently they are all 17x7.5 or 8 with 5x100. When i have the car and am ready to get started with the prep ill give enkei a call and see if they plan on adding it, we'll see. ive been going through catalogs and growing more and more disappointed in the lack of stock legal options. For a set of ccws you are going to drop over 2k dollars. Im not keen on racing on koseis or rotas. Ill probably end up with a set of team dynamics pro race 1.2s unless oz or enkei confirm addition of 17x7 with 5x100.
