Which autocross class?
 

What class will the BRZ/FRS run in?

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.

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.

If you are interested in the classing discussion that horse has been beat quite thoroughly on the scca forums
Frs/brz classing

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.

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.

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 !!!

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.

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:
mind my asking where?

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?

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.

this was a couple of minutes ago..

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...

Bill

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

Bill

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.

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. :sigh:

When I talked to Enkei a few weeks back, they didn't really seem too keen on adding anything in stock sizes. I thought it would be relatively easy for them to drill their 17x7 in 5x100 but I was wrong. I guess the openings are cast, which is probably a good thing to know.

The guy I talked to said they could do large batches, but it would require prepayment and an extended lead time.

If you go with the Team Dynamics, be sure and call Paul at Team Illuminata.

Maybe I did...sorry..I had just got done arguing with my wife over something stupid...ended up we were both right...:lol:...Kinda like this thread..:)... CCW, Fiske will custom make whatever you want...949 Racing should have a Subaru Specific Wheel as well..:)... seriously sorry..wasn't trying to butt heads...esp. since my wife had already pissed me off...BTW ...Her and I are good now...

Nothing wrong with Rota's...or the Kosei's...I know people that run both and have had great success....I, myself will be running the DPT's on the BRZ..and have no worries what-so-ever...Many National level folks run Rota's ...Karen K, McCance Just to name a couple... I guess a better question is: If your just going to Race on them, then Why not???

:)

Bill

Yup, that was the plan :)

Yea, Maybe we could set up a GB at some point for stock class legal rpf01s if there is enough interest from the stock class community... I see it as a tough sell though., most non-stock class autocrossers arent going to want a 17x7 aftermarket race wheel.

Fair point, I was unaware greg ran rotas, was that when it was in STX? I thought he had a set of enkeis And a set of volks, though i guess those could have been the rota volk knockoffs.

Im gunshy with the bargain brand wheels when racing... Ive seen a mini flip on completely level concrete due to a wheel failure and cracked spokes which if driven on much longer would have competely separated from the hub, id rather just have a comfort level with what im running on. The probability is probably no less or no mor with an enkei or a td wheel, but its more just a mental thing.

I understand the hesitation... Tom Hoppe ran Rota's back when in DS. Keith Casey Ran Rota's on his STX drive. Even SuperMan, Mike King has had Rota's on his ride way back when..I not saying they are the end all , beat all....all wheels are subject to failure...I have seen a custom CCW blow out..its not common...but it does happen. ... Hope we all can learn together and share the info is going to be key to the success of this thing..:)

Bill

Thanks for all the info guys. I saw the Kosei K4Rs but I wasn't too keen on running spacers. I've heard of Team Dynamics but haven't seem many by me (granted I've only been racing a couple years.). I'll check them out.

Danny has them on his Mazda2. I will probably get a set of 13x9-10 for next year. Their a know commodity. What you want is the ProRace 1.2.

13x9/10 for the Caterham or Miata? Yea I got in touch with one of the site vendors here but he said its 10-12 weeks from the UK which will pretty much be the end of race season.

The 'June' Fastrack is out: http://www.scca.com/about/?cid=44415

No mention of anything regarding the BRZ/FR-S.

:(

:brokenheart:


Perhaps it is because they have not met the required 1000 sales to be officially classed by the time of publication... though I would have a hard time believing that over 1,000 I4T and V6 Genesis coupes (individually) or Fiat 500 Abarths have been sold to date. Very much confused by this omission. :thumbdown:

GREAT NEWS :)

Something All STOCK BRZ owners will be interested in from the Service manual:

Replace the upper mounting bolt of the shock absorber ASSY FR and knuckle with a replacement bolt. (Part No.: Flange bolt 14×60 (901000394)). The range adjustable by replacing the bolts is 0°± 45'.


From my understanding there is a Stock (Crash bolt for the Scion also)

yep...Still waiting on my official Submitted letter..:/

Seems like rpf1s are always the way to go, if they fit, for bang for the buck. Aren't rotas generally heavy because they aren't fully forged? Weight will be huge on this car.

I am withdrawing this statement. The June fastrack was already posted, it is from the April 25 meeting. The July fastrack is the one we are waiting for, based on the May SEB meeting. :thumbsup:

The June fastrack was already posted where? in hardcopy? (I'm not currently a member, so don't get any mailings.)

I know it just showed up very recently on the website I linked, but if it was posted elsewhere earlier, I'd love to know where to keep an eye out for the next one!

If you look at the first line of the Solo Section it says the meeting date, which was April 25th for the SEB. The meeting where it was discussed was May 9th, after the SEB meeting... so I would assume that we'll probably hear in the July publication. The June one may not have already been posted, I read these things so often I can never remember the latest one and they don't supply a "posted date".

They get posted around the 21st-23rd of the month, according to my email notifications... so we have a full month until the July one.
