Need help classing my car:

[No_Torq]

2007 Civic Si:

stock gear type LSD

Strup 4-2-1 Header

Injen MR CAI

Ingalls TQ Damper (Powerstick)

Volk Racing F-Zero Kuwagata 18" x 8" +48mm offset

Nitto Invo P225 40ZR18

Thanks for your input!

I am not the best at these imports, but see page 68 on of the SCCA rule book (http://cms.scca.com/documents/Solo_Rules/2009_Solo_Rules.pdf). Hopefully someone else will double check for you.

I am guessing STX based on the modifications and wheel width.

2007 Civic Si: (Stock would be GS)

stock gear type LSD (If it came with it from the factory - GS)

Strup 4-2-1 Header (Bumps you to ST - Street Touring)
14.10 ENGINE AND DRIVETRAIN
D. Exhaust manifolds and headers may be replaced with alternate
units which are emissions-legal. Relocation of the oxygen
sensor on the header is permitted. Alternate oxygen sensors,
including heated types, are permitted. This allowance does not
permit relocation of the catalytic converter (see 13.10.E).
Exhaust heat shields may be modified the minimum amount
necessary to accommodate allowed alternate exhaust
components

Injen MR CAI (ST)

14.10 ENGINE AND DRIVETRAIN
C. The air intake system up to, but not including, the engine inlet
may be modified or replaced. The engine inlet is the throttle
body, carburetor, compressor inlet, or intake manifold,
whichever comes first. The existing structure of the car may not
be modified for the passage of ducting from the air cleaner to
the engine inlet. Holes may be drilled for mounting. Emissions
or engine management components in the air intake system,
such as a PCV valve, or mass airflow sensor, may not be
removed, modified, or replaced, and must retain their original
function along the flow path.

Ingalls TQ Damper (Powerstick) (ST)

14.10 ENGINE AND DRIVETRAIN
J. Engine mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Engine
position may not be changed. The volume of metal in a
replacement mount may not be increased relative to the volume
of metal found in a stock mount for the particular application.
Solid metal mounts are specifically prohibited. Any non-metallic
inserts may be used.
Hydraulic shock type rear engine locators, or bobble struts may
be replaced by manufacturer’s performance part, or aftermarket
replacement part. This part must retain factory dimensions and
attachment points, including factory design. (Example: If factory
locator/bobble strut is gas or hydraulic piston type, replacement
part must be gas or hydraulic piston type. No solid mounts may
be substituted.)

Nitto Invo P225 40ZR18

14.3 TIRES
Tires must meet the eligibility requirements of the Stock category
(excluding 13.3.F), with the following additional restrictions:

ST, STS – 225 mm
STX (AWD), STU (AWD) – 245 mm
STX (2WD) – 265 mm
STU (2WD). – 285 mm
B. Tires must have a minimum tread wear rating of 140.
C. Tire models must not appear on the following list, which may be
altered at any time by the SEB upon notification of the
membership.
Pirelli P Zero Corsa

14.4 WHEELS
A. Any wheels are allowed with widths up to the following:
ST, STS – 7.5"
STX (AWD) – 8"
STX (2WD) – 9"
STU - unlimited

My header is a race header so it does not have a cat. How stringent is tech. Would they still allow me to run STX? I'm not trying to squeeze by or undermine the system. I just want to make sure I'm not jacking anyone around.

It's actually not tech's job to determine if a car is legal for the class. It's the competitors. So if you are up front about it to your STX competition they may say go ahead. If they have a problem (which may happen if you start winning or taking trophy spots) then you may have to run DSP or SM. Both of those classes have fun competition as well though.

Good luck!

Well in that case it may not be that big of a deal. It's my first time out on the track with a Civic Si. I doubt a header is going to grapple with the Mini amongst the others in the class. Sounds good, I appreciate the replies guys!
