Porsche 911
997.1
(2005–2008)Performance— 6 options
Full Sport Chrono Package with PCM integration, Sport and Sport Plus modes, and — on 997.2 PDK cars — launch control activated via Sport Plus mode. Standard on the Turbo S. Widely regarded as the single most value-critical option on 997 resale; cars without it are noticeably harder to sell, particularly PDK 997.2 examples where Sport Chrono unlocks launch control and the full Sport Plus chassis sharpening.
Factory sports exhaust providing a louder, more characterful note. Critical distinction between generations: the 997.1 unit had a permanently open bypass valve with no quiet mode, making it notably intrusive on long motorway runs. The 997.2 introduced a switchable bypass valve (Porsche Sport Exhaust, PSE), allowing the driver to toggle between restrained and open modes. Standard on the GTS. The switchable 997.2 PSE is considerably more desirable and usable day-to-day than the fixed 997.1 version.
Factory performance upgrade for the Carrera S and 4S only, adding approximately 26 hp on the 997.1 (to around 381 hp) through revised intake manifolds, optimised exhaust headers, and modified engine mapping. On the 997.1, the X51 bundle includes the sports exhaust and Sport Chrono Package. Available exclusively on Carrera S/4S — not applicable to the base Carrera. Adds meaningful performance headroom and commands a significant premium on the used market; verify with Porsche's online vehicle history check.
Adds a dashboard-mounted stopwatch timer, Sport and Sport Plus driving modes, and reduced throttle response lag. On the 997.1 this is the entry-level Sport Chrono and does not include PCM integration or launch control — those require the Plus version (640). Buyers specifying a 997.1 should prioritise finding code 640 over 639 where possible, as the Plus version is materially more capable.
Standard gearbox on most Carrera variants. The 997 manual is widely regarded as having one of the best gearchange actions of any sports car of its era. On 997.2, the manual foregoes PDK launch control but retains the mechanical connection that many purists prefer. Note that the code 480 will typically not appear on a build sheet if the manual was the standard specification for that trim level.
5-speed torque-converter automatic available on 997.1 models only. Significantly slower than the PDK that replaced it on 997.2, though adequate for relaxed road use. Tiptronic-equipped 997.1s are generally less sought-after than either manual or — where applicable — PDK examples on the UK used market. No launch control capability.
Chassis— 3 options
Factory ceramic composite brakes with yellow calipers, offering reduced unsprung weight and exceptional fade resistance at sustained track temperatures. Standard on the Turbo S and GT2/GT2 RS; optional on all other variants. Replacement ceramic discs and pads can exceed £10,000–£20,000 per set — inspect carefully for crack propagation in the disc vanes, which renders them unfit for use. Many UK buyers prefer the lower running cost of iron brakes; PCCB cars command a premium for track use but can be a liability on high-mileage road examples.
Electronically controlled adaptive dampers with Normal and Sport settings selectable via the centre console. Optional on the base Carrera; standard on the Carrera S, GTS, Turbo, and GT3 — where standard it will typically not appear on the build sheet. Sport mode firms the dampers for reduced body roll and improved cornering precision with a real-world handling benefit. A distinct separate code (030) denotes the stiffer, lowered PASM Sport Suspension available on the 997.2.
On 997.1, a purely mechanical 40% locking rear differential biasing torque under acceleration. On 997.2, this code denotes Porsche Torque Vectoring (PTV) — a mechanical LSD combined with brake-based torque vectoring for improved cornering balance and rotation. Standard on Turbo S. A significant upgrade for performance-focused buyers, especially on rear-wheel-drive Carrera variants; adds noticeable traction and agility without electronic complexity.
Wheels— 3 options
Optional 5-spoke Carrera Classic alloy wheels in 19-inch, a timeless design that works well on both base Carrera and S models. A popular period-correct upgrade over the standard fitment. Generally well-preserved on pampered examples; check for kerbing damage on the inner rim.
Optional 19-inch Sport Design alloy wheels with a more aggressive multi-spoke appearance. A popular upgrade choice on more sporting 997 configurations. Often paired with the Aerokit Cup (XAA) for a cohesive exterior presentation.
Replaces the standard silver wheel centre caps with coloured Porsche crest caps (typically in the body colour or a contrasting colour). A subtle but period-authentic finishing detail that enthusiast buyers appreciate on well-specified examples.
Exterior— 5 options
Factory custom paint colour outside the standard palette, warranted by Porsche. PTS 997s command a significant resale premium for desirable colours; however, repainting or repairing PTS finishes is substantially more expensive than a standard colour. Always verify the PTS colour code against Porsche's build records before purchasing — the specific colour drives the premium, and rarer choices carry more uplift than commonly requested ones.
Factory aerodynamic package featuring a deeper front splitter and a more aggressive fixed rear spoiler configuration, providing additional downforce and a markedly sporting visual stance. Popular on track-biased 997 builds. Cannot be retrofitted economically — a factory Aerokit car is clearly preferable to an aftermarket approximation.
Single-bulb HID xenon headlights without dynamic cornering function. Standard on the Carrera S on the 997.1. A meaningful upgrade over the base halogen units for night driving, though superseded in the 997.2 by the PDLS-equipped xenon option (603).
Factory electric sliding glass sunroof for the coupe body style. Note there was no panoramic roof option available on the 997 generation at all — the 650 is the only factory sunroof choice. Mechanism is generally reliable but sunroof seal deterioration can cause wind noise on older examples.
Factory deletion of the model name badge from the rear of the car. No mechanical or performance significance. Easily verified — the rear panel retaining holes are blanked from factory on debadged cars.
Interior— 10 options
Fixed-back lightweight sport bucket seats. Standard on the GT3 RS; optional on the GT3. No backrest recline adjustment — check fit carefully before purchase as they cannot be modified. Code 384 = driver, 385 = passenger. Highly sought-after on track-focused 997 GT3 purchases; less desirable for tall drivers or regular road use.
Multi-way electrically adjustable sport seats with lumbar support and position memory. Code 377 = driver, 378 = passenger. The most popular seat upgrade on UK-market 997s — a step below the more comprehensive 18-way seats found on the 991 range. Generally reliable; check for worn side bolster leather on driver's seat.
Extends leather coverage to surfaces beyond the standard specification, including the dashboard, door panels, and pillars. Significantly elevates interior quality and adds meaningful resale value on well-specified cars. Check for cracking or fading on sun-exposed dashboard surfaces, which can be costly to address.
Extends special-grade leather coverage throughout the cabin beyond the standard specification. The 'special leather' grade denotes a higher-quality hide than the natural leather (796) option. Typical of more expensively specified Porsche Exclusive cars; adds notable resale value and collectability.
Fixed-backrest sport seats with a fibreglass-reinforced shell for improved lateral support versus the standard comfort seat. Manually height-adjustable. Code 375 = driver, 376 = passenger — ordered as a pair. A popular mid-level choice that provides sports car feel without the harshness of full buckets.
Factory-specified contrasting two-colour leather scheme across seats, dashboard, and door cards. Popular aesthetics option that elevates the interior significantly and commands a modest resale premium on well-chosen colour pairings.
Factory carbon-fibre trim inserts across the dashboard, door panels, and centre console. Complements track-focused builds and pairs naturally with bucket seats and Sport Chrono. Check for delamination or edge lifting on older cars, which is not straightforward to repair to factory standard.
Alcantara suede-effect headliner replacing the standard cloth roof lining. Standard on the GTS. Adds a premium, motorsport-derived feel to the cabin; a common inclusion on higher-specification 997 builds. Check for fading or staining — Alcantara headliners are not straightforward to replace.
Factory seat belts in Guards Red replacing the standard black (code 555). A purely cosmetic option but a well-regarded specification detail that adds period character. Carries a modest premium for enthusiast buyers who appreciate the factory detail over aftermarket alternatives.
Factory seat belts in Speed Yellow replacing the standard black. Typically specified on Speed Yellow exterior cars or for contrasting interior effect. A niche colour option with genuine factory provenance.
Technology— 5 options
Bose 9-speaker surround sound system with amplifier, the highest audio upgrade available on the 997 — no Burmester option was offered. A genuine step up in audio quality over the standard system. Generally reliable; amplifier units can fail on high-mileage cars but replacements are available from specialist suppliers.
Porsche Communication Management 2 base module providing the head unit with radio functionality. Navigation was a separate add-on (code 670). PCM 2.0/2.1 on the 997.1 has limited connectivity by modern standards — no Apple CarPlay and no native Bluetooth audio streaming. The 997.2 used PCM 3.0 with a touchscreen. A Porsche Classic Communication Management Plus (PCCM+) retrofit is available for approximately £1,200–£1,500 through Porsche Centres to add modern connectivity.
Factory navigation add-on module for the PCM 2 system (requires code 665). The Porsche mapping system is now outdated by modern standards and most owners rely on smartphone solutions or the PCCM+ retrofit. Presence indicates a more comprehensively specified example at time of original sale.
Ultrasonic rear parking sensors providing audible proximity warnings. Note that no factory reversing camera was available on the 997 at all — this is the only proximity aid the factory offered. A practical convenience option, particularly given the 911's limited rearward visibility.
Factory cruise control for motorway use with no adaptive capability. Absence is not a significant detractor for shorter drives but is a meaningful convenience on longer UK motorway journeys.
Option availability varies by variant and model year. SA codes are factory order codes — verify against a Porsche Certificate of Authenticity (COA). Listing counts update in real time.
