Post Car Classing Help Questions Here!

[Kurt Rahn]

The PDF on the SCCA website hasn't been updated since last march, and for Hyundai just has one entry that says "all models: HS". It seems to me that the new Hyundai Genesis Coupe should be classed in something other than HS, does anyone know what it's classed as for 2010, or if there is a 2010 PDF somewhere that I couldn't find?

The turbo is GS and the V6 is FS.
Edit: You beat me, quick-draw McBerry!

What run group do production electric cars run in? Would they always run with or after another class?

Thanks
George

if you mean the local EL class.. I don't think anyone has run it in quite a while. I added it to the run order just in case.

[Suren Yegiazaryan]

Where will I be classed?

1990 Acura Integra
Koni Yellow Sport and Ground Control Coilovers custom spring rates
Custom Cat Back Exhaust system
Metal Master Brake pads all around
Full Interior
Stock Engine B18a1
Stock Wheels

Where would I be classed if I add:

Intake
Header
Cat-delete

As it sits you would fit squarely in ST as long as you are using 140 (or higher) treadwear rated tires. You could still add the header and stay in ST. If you remover the cat that bumps you to DSP where you could use DOT-Legal Race compound tires.

Thanks Sebastian. The STS classification confused me for a sec but now I see STS is for 2 seaters. I thought the height adjustment capabilites of the coilovers moved me to STS.

Hey guys,

I've been running CST for awhile now, but all of a sudden the CST class is getting REALLY full at events. I drive a Datsun 240Z with a V8 swap and was wondering if I could be under any class aside from CST. I asked this question awhile earlier and got some responses that told me that the only option I had was to do XP, but I don't think we run XP here. I'm just wondering if there have been any changes in the rules which would perhaps allow me to change classes within our region without breaking any rules.

Thanks!

Yes we run XP, as part of CPM (Combined Prep/Mod) which is all the Prepared and Modified cars indexed together. We just don't get enough of those cars to have individual classes.

Not sure why you see that as a problem. If by that you mean the competition is daunting, all the other classes you could run are typically faster. But I guess a V8 datsun can probably run CST, CSM, SSM, XP, EM and I suppose AM for completeness. The latter three all fit into the CPM-index, and XP would have the best index number. You would benefit greatly by upgrading your tires to match the class you want to enter.

Maybe they'd let you run historic with a CST index. You could check with Brian Howlett.

[Jayson Woodruff]

But I guess a V8 datsun can probably run...SSM....

Probably not, would need to be a nissan motor.

Ok, here's a hard one - I think SSM, but I'm not sure.

1989 Mazda RX-7 Turbo. Motor has been street ported, larger fuel injectors, modified the turbo (stock turbine side, new compressor housing/wheel), the car is running Haltech ECU. Some suspension mods as well (Springs/Struts). Does have a 3" down pipe and have removed the catalytic converter.

So, what class am I in?

Thanks,

The trubo puts it into SSM. If it wasn't for that I think it may be ASP, although you would have to check on the street porting thing.

Another car - my wifes. I believe is STX, but not sure.

2002 VW Jetta 1.8T. Stock motor, cold air intake, down pipe to cat to catback exhaust. Springs/Struts/Swaybars. 17 X 8 Wheels w/ 225 wide tires.

Thanks!

Dang that was a fast reply! I think your allowed to run water injection in SSM, right?

SP legal so therefore SSM legal.
15.10.G. Intake water injection systems are allowed.

14.4 WHEELS
Any wheels are allowed with widths up to the following:
ST, STS, STR (AWD) – 7.5”
STX (AWD) – 8.0”
STX (2WD), STR (2WD) – 9.0”
STU – unlimited

So it would be STX, because of the 8" wide wheels. Good to know!

Thanks Rick and Bill! I actually have no problems running CST, its just that I want to keep my options to classes open. I need a lot more seat time + a TON of suspension upgrades to get competitive in CST, let alone XP!

[Q V]

If you are only planning on competing locally for the foreseeable future, CST is the easiest class to run in for street tires. We have a wide enough range of cars/drivers this year, so there's bound to be someone you are close to in times!

I know this is a car classing thread but don't forget to take advantage of "Instructor Runs" if you don't do so already.

hey everyone, I was wondering what class i would be in, I have an 08 Scion tc

-rear sway bars
-stock rim
-stock tire size 215/45/17
-cold air intake
-dezod full catback 2.35 exhaust
-lowering spring on stock strut
-short shifter
-everything else is stock

-I was also wondering if I got coilovers would it change the class?
-Also I've been reading that the exhaust has to be a certain db to run sometimes. My exhaust is a full catback and I added a longer resonator, but I'm not sure if still under 95 db, is there anyway I check it?

95db is pretty loud. I'm sure yours which you made quieter is under. Some ST cars under the limit only have a resonator and end after the driver.

Hi Daniel,

Your car is also eligible for the local CST class (California Street Touring)for street-licensed cars, where you can pretty much run amok with modifications as long as the car has street tires with a treadwear rating of 140 or higher (if you have stock tires, they most certainly qualify here).

--Doug

[Daniel Vu]

^^ oh thanks doug, I might stick with other class for now. I don't really plan on any other power mods. I haven't been to one autocross event yet, what day would you guys recommend for me to go try it out? I don't want to show up on some pro day and embarrass myself
