As is you are in BSP.

If you put back the stock steering wheel you would go back to STU

My car is a real euro spec, so I can safely say SM-S?

 

From Page 1, If your car was sold new in Europe and imported to Canada at a later date it would be classed as Street Modified SM-S. It is not eligible for Street, Street Touring or Street Prepared classes based on differences from the North American model.

 

Outside the WSCC the car would be classed as D-Modified. We made a concession to allow  imported vehicles to compete in Street Modified (with SM legal modifications)

Verification of my reading:

 

JDM 2000 Subaru Impreza WRX STI

 

Would be Street Modified?

 

According to the Classificaiton Worksheet:

- OK: Brembos. Currently on stock brakes, but intend to put on the brembos (assuming the new wheels will clear them).

- OK: Front subframe brace. Currently not on car, but intend to put on

- OK: Aftermarket exhaust. Currently on car. Passed MB safety.

- OK: Tires: Yokohama Advan Sport v103 215/45/17 (What's the tire rating? 180?)

- OK: Engine displacement: 1990 cc

 

I believe the rest of the car is stock, specifically sway bars, springs, struts, front strut tower brace, block, turbo, fuel system, intake, intercooler, ecu, etc.

 

Other things I intend to do at some point:

- Tune: Once I find a good solution, I want to tune for local conditions (air, fuel, not looking for more power)

Your car would be classed as Street Modified due to the vehicle being a JDM RHD model. All the modifications you listed are legal for use in Street Modified (SM)

.

Hope to you see you out in 2015!

I would like to double check:

 

2003 BMW 320i (E46 non-m) it is  2200cc 6 cylinder (M54B22)

 

Current

Eibach sportlines

Koni sport adjustable

CAI

factory performance short throw

 

Tentative:

cat-back

underdrive pulleys 

sway bars

 

Then what would I be if I went with a Header**?

 

Does it change if I go header and no cat back?

Looks to me like you'll be in Street Touring, even with the cat-back, pulleys, and sway bars. Even with a header. However, you cannot delete the catalytic converter, so be mindful of that when redoing your exhaust system. Also you need the exhaust to exit behind the driver or side of the car. All these rules are in the 2015 rule book (link). Check the Street Touring Section starting on page 81. Specifically 14.10 talks about engine modifications including exactly what you are allowed to do for your exhaust and intake.

Just to clarify, In Street Touring if there are multiple catalytic converters, you MAY delete some, as long as one remains. A good example is if there is an integrated cat in the header, you may replace the header with an aftermarket unit that has no cat as long as the downstream unit remains in place.

 

"Catalytic converters: Any catalytic converters are allowed, but must attach within 6” (152.4 mm) of the original unit. Multiple catalytic converters may be replaced by a single unit. The inlet of the single replacement converter may be located no further downstream than 6” (152.4 mm) along the piping flow path from the original exit of the final OE converter."

All current modifications would put you in Street Touring (STX)

Any cat-back, sway bar or underdrive pulley is also legal in STX

 

A header is legal for STX however it must retain a cat converter within 6inches of the original unit. If the header does not conform to this the car would move up to Street Prepared (DSP).

 

Both are great classes for the BMW 3 series. Here's an example of what DSP is all about: http://www.solomatters.com/shop-manual-chapter-9-d-street-prepared

Can someone just confirm a few things for me. I'll be running my 2012 Audi S4 which has the 3.0L supercharged engine. I know I am in BS and plan to be there for the remainder of the season. But I want to understand where I will progress.

 

I could move to STU but I would have to drop from the stock 255 to a 245 tire due to the AWD tire regulation.

 

From there I think I go to ESP based on the catch-all "Other sedans over 3.0L not otherwise classified." however it could be CSP because of the catch-all "Sedans over 1.7L & under 3.0L not otherwise classified." because my car is neither over or under 3.0L...it IS 3.0L! My assumption is ESP but is that correct?

 

After that it's SM.

 

And eventually, in a few years, once warranty has run out, I might do a pulley swap on the supercharge and get a Stage 2 tune which forces me into Prepared, correct? But where in Prepared.

 

 

I don't really worry about maximizing where my car is in a class and I don't let the class really dictate what I do to may car. For example I will probably end up in ESP next year simply because I want to do brake lines and keep my 255 tire or go up to a 265. Neither of those mods will make me faster that I will overcome the PAX hit, but I'm not too concerned...if I was I sure wouldn't be driving an VAG product at autocross. That said, once the TT is complete it should be pretty awesome.

I'm pretty sure over 3.0L means 3.0 AND over so yeah ESP.

The engine mods would just put you in Street Modified as far as I can tell not Prepared. SM allows pretty much anything done to the engine as long as its from the same manufacturer as the chassis.

Ah okay I reread the SM section and I was looking for specific text saying superchargers and/or the pulleys can be changed and it is not specifically mentioned but I missed this important line "Drivetrain and related components (induction, ignition, fuel systems, etc.) are unrestricted except for the following limitations:" which I suspect covers the pulley swap since they are not referenced as a limitation.

You seem to fit right in SMF with the same manufacturer engine swap. If you had street tires, you'd be in SMF-S. Hoosiers put you in SMF. You can update your current registration on MSR accordingly.

As Mohamed posted above, as long as your strut tower bar does not triangulate with the firewall and you have retained a full interior (doors panels, carpet, headliner etc..)you would be a perfect candidate for Street Modified FWD . If you decide to race on Hoosiers or any tire with a tread rating below 140 TW you would be classed as SMF in our mixed group. If are using Street Tires with tread wear ratings of 140 or better you would be in SMF-S in our Modified Street tire group.

Just a quick note on tires, as it has been mentioned twice.

 

There's nothing stopping you from running Hoosiers. You would be classed in SMF, which is in the Mixed Division with other SM and SP cars that use R-comps. The Mixed Division also includes all the Street Touring cars.

 

Locally, we have a separate trophy division called "Modified Street Tire Division" where you can run against other SM and SP cars using only street tires. All classes are appended with a "-S" in this division, so in your case if you had street tires you want to register in SMF-S.

 

The main reason you might want to consider running in SMF-S with street tires, as the other guys have suggested, is due to the number of other competitors who also do this. It means there will be more direct competition for you and likely more fun as well. However, you're free to compete in either of these classes and divisions, it's totally up to you.

 

I hope that makes sense. Maybe just bring whatever you have to the first race, ask around and check out the other guys to see what they're doing, then you can change your mind and buy something if you want to do that. No need to buy new tires if you already have a good set.

I have an Integra that would fall under DSP (stock motor, lsd, aftermarket shocks/springs, front+rear sways and control arms, no rear seats/interor trim).

 

Looking at the first post 'How Car Classes are Divided into Groups for the WSCC' I would be classed in your 'Modified' category, correct? Which allows tread rating of 140+.

 

What if I decide to throw on r-comps? I would then move into 'Mixed'?

 

Finally, what classes are trophies awarded for?

you are correct about everything except that you are only allowed to removed the rear seat in SP. removing any other interior trim moves you into SM. (Also not sure about control arms in SP)

 

Trophies are awarded for each group. ie trophies for Street, Mixed, and Modified Street.

I don't think you can remove interior trim in any of the "Street" classes. Even Street Modified.

 

Edit:

 

15. Street Prepared

1. Allowed Modifications

F. The driver and front passenger seats may be replaced with the following restrictions: Seats must be securely mounted per Section 3.3.3.B.3. The seating surface must be fully upholstered. Any replacement seat must be a full back, bucket-type automobile seat incorporating a functional headrest. Kart seats, low-back dune buggy seats, and other similar types of seat are expressly prohibited. Cars may have no fewer than the standard number of seats. The seat tracks are considered part of the seat and may be substituted. Alternate seat tracks may serve no other purpose. The standard seat belts may be removed to facilitate the installation of alternate restraints complying with safety requirements. An alternate seat which replaces an airbag-equipped seat is not required to have an airbag.

 

 

16. Street Modified

1. Allowed Modifications

K. Rear passenger seat(s), including restraints and associated hardware may be removed

 

So I guess seat removal is restricted to SM classes and interior panels can't be removed just for the sake of removing them. I think they can be modified or trimmed to accommodate certain modifications though.

The car is 20 years old and I don't like squeaks, haha. There are no interior panels or trim behind the front seats including no headliner or carpet. Otherwise, front seats forward is full interior trim.

 

In this case, if I fall into Street Modified, in terms of WSCC classes, I'm still in 'Modified' if I run street tires or 'Mixed' if I run on r-comps, correct?

 

---------------------

 

 


Trophies are awarded for each group. ie trophies for Street, Mixed, and Modified Street.

 

I noticed on your results page, in addition to the 3 categories you just mentioned, there is a Novice list. Is this simply the 'NYC (Not Yet Classed)' metioned in the first post of this thread or something entirely different? Are trophies awarded for this class as well?
