I figured out what this thread was about lol all is well.

I'm very happy to hear this. I competed locally in STX for a few years in my Mustangs, and we have a great bunch of guys locally in the class in a variety of different platforms that provide some good competition. Most likely next year I'll be swapping back and forth between my Mustang and BRZ in STX and might even throw some springs and swaybars on our Forester XT and bring it out if the weather is particularly cold or wet.

This thread makes me sad.

Why? Were you hoping for STR?

Nope. Nothing about the actual ruling. Just in general I'm sad that to be competitive in a class that is just one set of mods away from 'stock' one has to compromise OEM powertrain reliability.

You do have a point. Personally I don't plan on trying to make mine nationally competitive, mostly local events with an occasional divisional or national tour event, and I'm not going to be pushing the ragged edge, risking any powertrain issues, just isn't worth it to me for what I want out of the car.

What makes you think a STX build will result in an unreliable powertrain?

If your tune isn't aggressive - you're leaving time on the course.

This is splitting hairs, though. You could say the same about Wheel X being 1lb. heavier than Wheel Y, but at the end of the day, it's all within noise. A reasonable E85 tune will still make more power than any 93 tune and be just as safe, if not more so. :iono:

Nevermind the fact that power is pretty far down the list of importance anyway...

In the end I don't think you'll have to tune to the ragged edge to get it competitive.

anyone else read the bulletin in full?

the following rule change offends me...


"2. The use at an event by any participant of any federal Schedule 1 controlled substance (including marijuana) (ie, we're writing this rule specifically for all you crazed potsmokers out there that are poisoning our crops and stealing our children in the night),
or other drugs that affect the ability of the participant to safely participate in the event or may otherwise adversely
affect the safety or integrity of the event, is specifically prohibited. Any participant who violates this prohibition
• shall not seek to participate in the event
• may be excluded from the event by the event chairman
• may be removed from the grounds by the order of the event chairman or chief steward
• may be penalized as provided in Section 9.
As a condition of continued participation, the participant may be required to submit to such testing procedures as
may be established by SCCA in its sole discretion. Failure or refusal to submit to such testing shall be deemed
a violation of the above prohibitions. However, SCCA assumes no obligation or duty to establish such testing
procedures and/or to test participants on a random basis or in a specific case."

In my experience with SCCA rules, things like this are added/changed/modified because it was an issue at an event within the last year.

I'm not offended but I guess its because I don't want people doing drugs or under the influence of them anyway while racing. Plus its an insurance liability. I hear they make you paranoid...

You mean it's bad to be high as a kite and then attempt to pilot a nearly 1.5 ton pile of steel and aluminum quickly around a parking alot with people standing around nearby? I can't for the life of me understand why they wouldn't appreciate this.

The SCCA is going to drug test us? WTF?

weed is not alcohol, crack, shrooms, LSD etc.

Every day the government shoves it down your throat that weed is bad and now we have another organization enforcing the lies.

While I am generally for the total legalization of marijuana I don't think an autocross is necessarily the right venue for that.

Back on topic, what are folks using for brake pads? I've had good luck with the Stoptech pads in the past and was just going to go with those for street and autocross.

For the STX guys, Essex has this AP brake kit out for the BRZ which drops 20lbs off the front of the car:

I've had mixed results with the Wilwood Dynalite calipers but if you really want something lightweight these should bolt right up and are quite a bit cheaper.

I dont feel weed is bad. I meant for purposes of racing, it belongs far away. Free time at home chillin or out a party, no problem with it.

I put Carbotech AX6 but on RS3s, I cant get enough tire heat on an autocross to keep the pads from overpowering the tires. On the track it's great. Im thinking event he basic AX6 pads are overkill on this lighter car while on street tires.

i know people with chronic pain that use weed to relax, they are highly functional when they use it.

a close friend of mine eats weed cookies/brownies through out the day to ease her pain. You wouldn't know if no one told you. So now she's banned from autocross events?

You have a very narrow view of what a marijuna user.


Also, i'd like to see you tell someone like Nick Diaz that weed is only for "chillin."

I dont disagree with that use, I kinda figured it was implied that if I was okay with it for normal people relaxing that I had no problems for people using medicinally. Doesn't change my idea on anyone that needs it using it during a competitive driving event. There are many prescriptions people need that limit what they can do while using that drug, at least for a certain amount of time after it's used.

Either way, enough thread derailment.

For those of us who are not SCCA AutoX regulars. Can someone do a simple break down of what mods are allowed and expected to be competitive in STX.

I always use this spreadsheet to check what is ok. Its from 2009 but I'm sure 90% of it is correct... http://azsolo.com/classes/car_class_worksheet_2009.pdf

sure...Some of the allowed mods:

-suspension: coilovers, springs,Struts, Swaybars, Bushings
-brakes: Stainless lines, Fluid, Pads and Brake Kits as long as they are the same size or bigger than stock.
-Lightweight Battery as long as it has the same output as stock
-Engine: Headers, Exhaust w/Cat(within 6 in of original) and has to exit behind the driver, Tune..if you have stock boost...you can't touch that...Timing only and fuel and any Intake up to the Throttle body.
-STREET tires...up to a 265 width with no less than 140 treadwear for 2WD's along with up to a 9in wheel is allowed...
there some other stuff but thats just of it... motor size limits and whatnot..

Bill

Cold Cranking Amps or voltage?

voltage...:)

one thing to add to the exhaust portion is if the car has 2 cats, only the primary cat needs to be kept and it can be replaced with a high flow after market cat. the pre cat may be deleted.

For my own Reference:

So.. what are our options within that restriction?

Interesting. So a 300 cell cat is required. I believe most vendors on the forum are using a 200 cell.

not true...only a 100 Cell is required...but it has to be at least 3 inches long...:)

Bill

What am I missing from the info you posted? 100 cells per inch, 3 inches. Seemed like 100x3=300.

Could you elaborate on your logic/explain it for me?

the cat has to be at least 3inches long....with a min of 100 cell per inch ..so for a 2.5 in exhaust...it has toe have 250 cells...that is 3 inches long..:)

Bill

Ah ok. So they are referring to diameter and not length. I was confused.

Thanks for clearing that up.

Exactly... ^^^ :)

most aftermarket has 1oo cells per inch as a Std...so I would say any of them would work ...I know Nameless and Perrin are 100 cells per in..
not sure about Vivids...

Bill

Here's the doc online, have at it: http://cms.scca.com/documents/Solo%2...categories.pdf

A great place to start...but not up to date with current rules. (circa 2006 or so)
STR isn't even listed. and wheel and tire allowances have changed in recent years. :)..

There is a 2012 rulebook online at the SCCA website:
http://scca.cdn.racersites.com/prod/...ry_reduced.pdf

FASTRACK updates the current rule-set, which is why it is important way to keep up with the changes thru-out the year..:)

Expect the new rulebook to come out in Feb 2013..that incorporates all the past years Fastracks.

Hope this helps

Bill

I've done some more reading. The way I'm reading it, it's 100 cells per square inch. Perrin says they use a 200 cell cat. If it's really 200cpsi, then it's fine (you could actually go with a less restrictive cat), but if it's actually only 200 cells, then the cell density is too low. I'm not seeing much about cats below 100cpsi, so I'm hoping Perrin's 200 cell cat is 200cpsi.

thanks..:)..I thought I had seen somewhere they were using the 100...just confirmed 200 from Perrin.. sorry about the confusion ...and Per 'square' inch makes sense..:)


Bill

Thanks, here's the latest fastrack (I think: http://www.scca.com/assets/12-fastrack-oct-solo.pdf)
