2011 Subaru WRX STI S206
Explore the Subaru WRX STI S206: history, verified identity, specification references, rarity evidence and real credited photos.

The S206 refined the four-door STI through engine balancing, chassis development and a carefully defined complete-car specification. Its 2011 programme included an NBR Challenge Package within the overall 300-unit reference, a relationship that the inventory’s overlapping rows must preserve.
One programme includes the NBR package
STI describes 300 S206 cars, including a 100-unit NBR Challenge Package. The inventory separately lists the main car, the NBR package and a carbon-wing package reference. SUB-129 and SUB-133 are consolidated here as overlapping identities. This does not remove the package’s significance; it records the specification within its correct family instead of creating additional cars each time a package or component receives its own spreadsheet row.

The engine record is more useful than a badge alone
The factory specification lists a 1,994 cc EJ20, 235 kW or 320 PS and a six-speed manual transmission. The heritage account also discusses development intended to improve the power unit’s response. Those are original-model references rather than evidence about a modified car’s present output. Keep engine and calibration records in sequence, particularly where later parts could make an ordinary STI resemble the limited car’s specification on paper.
The NBR specification has its own physical features
The NBR Challenge Package is more than a decorative name, with special materials and aerodynamic equipment described by STI. An individual file should establish whether the car was originally ordered in that form, rather than assuming any S206 with an added rear wing is NBR. The included photograph is catalogued as an S206 with an optional wing; it is not used to authenticate a particular package allocation from appearance alone.

Chassis development is a coordinated arrangement
STI describes Bilstein dampers, dedicated springs, flexible structural components and forged BBS wheels with Michelin tyres. As interpretation, that list becomes meaningful when read as one model-specific tuning exercise. Individual components can be changed or fitted elsewhere. A careful present-day specification therefore separates original equipment from replacement and later tuning, avoiding the assumption that a familiar component brand proves the whole vehicle remains in its original form.

A shared cap needs a shared catalogue record
The parent profile explains both the standard S206 and its limited package without inventing a body or colour split. That structure also helps duplicate protection: a car advertised later with a longer package name can still match the same original identity. For a collector file, retain the VIN, complete-car record, package documentation and dated photographs. Numbered plaques support that evidence, but a removable marker alone does not establish the full chassis history.

Rarity and production scope
The S206 reference is 300 overall, with 100 NBR Challenge Package cars within it. SUB-129 and SUB-133 are consolidated as overlapping package records, not added as further production. The image is an S206 model illustration with an optional wing, not independent proof of NBR membership. Factory references remain attributed, and no new completed-chassis or current-survivor census is claimed.
What the photograph represents
The source identifies an S206 with an optional rear wing. This photograph supports the parent-model illustration; the wing alone is not used as proof of an NBR Challenge Package allocation.

Frequently asked questions
Are the 100 NBR cars additional to the 300?
No. STI identifies them within the S206 programme.
Does any wing-equipped S206 qualify as NBR?
No. The original package specification needs documentation independently of removable aerodynamic parts.
