I own this car and the best existing mod (LKSpec) was quite crude (understandable if a modder does not have access to the real car). I decided to update the mod. All credits go to MLSXLD and El Kay. I just made the mod more accurate. Let me know what you think.

I think the mod is tremendously fun and realistic to drive with TC off as that mimics the Porsche PSM



================================================================

LKSpec 2022 Porsche 911 992.1 Carrera S (Sahare Realism) (2.0)



What's New vs. the Previous Releas

================================================================



Built by an actual 992.1 Carrera S owner and cross-checked against real Porsche factory engineering data consisting of many sources, one of which is in the link above. This isn't a re-skin -- it's a physics and accuracy pass aimed at making the car drive, sound, and spec out like the real thing



V2 Changes:



\-Designed for TC off (mimics Porsche PSM)

\-suspensions.ini: CSP extended physics, corrected front TRACK (was reversed), corrected front spring rate, tuned Sport Plus damper rates from Porsche's published chart

\-aero.ini: refit CD\_GAIN using real top-speed data

\-ai.ini: retuned AI driver behavior

\-brakes.ini: 100–0 km/h braking distance \~30m (matches real car)

\-drivetrain.ini: increased diff lock under power/coast

\-electronics.ini: adjusted TC slip ratio for real 3.35s 0–100

\-engine.ini: increased engine braking torque, added throttle remap (no turbo boost below 45% throttle)

\-tyres.ini: raised cold pressures and grip coefficients on both compounds





V1 Changes:  


\-ENGINE & POWERTRAIN

\- Rebuilt torque curve to match Porsche's own factory dyno chart, including the correct low-rpm torque kink at 1,750 rpm

  
\- Rev limiter corrected to the real-world 7,500 rpm (was 7,520)

\- All 8 PDK gear ratios, reverse gear, and final drive corrected to match Porsche's published spec sheet exactly. 7th and 8th gears are overdrive gears. The top speed is in 6th gear.

\-Top speed changed from the dashboard readout of 330+kph to the realistic 309kph (confirmed by dragy on numerous different owner YT videos and my own car)

\-0-100, 100-200, 0-200, 0-250kph now accurate with GPS data. The old model was using dashboard readouts.

\- Clutch torque capacity raised to sit above the PDK's real rating of 800+

\- Turbo wastegate/boost response retuned for a more realistic build curve with the torque peaking at the actual 2300rpm and not later.



CHASSIS & HANDLING

\- Total mass recalculated from Porsche's actual curb weight (previous figure was roughly 3% too heavy)

\- Corrected Weight distribution, spring rates, and differential lock settings corrected to match real chassis behaviour based on Porsche engineering documents and spring rates

\- Steering ratio and steering geometry updated to better reflect the real car's variable rack

\- Chassis collider dimensions corrected for more accurate contact and damage behaviour



TYRES & BRAKES



\- Cold tyre pressures set to the real-world spec: 2.0 bar front / 2.2 bar rear



\- All-season tyre now has genuinely different (lower) grip than the Cup 2 compound instead of a re-badged copy, plus a fixed  cold-weather grip curve that was previously backwards

\- Corrected a sizing error on the rear all-season tyre

\- Brand-new CSP brake thermal model: realistic fade and cooling behaviour built around the real rotor and caliper spec

\- Braking power and front/rear brake bias corrected. Old model was at 0.8g, new model is at a realistic 1.3G with 1.4G peak on CUP2.



AERO & BODY ANIMATIONS

\- Drag coefficient retuned for more realistic top-speed behaviour. CG model adjusted to match actual top speed.

\- Rear spoiler and front cooling flap deploy speeds corrected to match the real car's actual activation thresholds

\- Fixed a wheel-blur bug that meant the effect almost never triggered



EXHAUST & VISUAL EFFECTS

\- Exhaust flame effects toned down from arcade-style to stock road car realistic -- the real twin-tip Porsche Sport Exhaust



(PSE) doesn't shoot flames

\- Anti-lag and flat-shift flame behaviour disabled to reflect how the PDK actually manages power delivery



DASH, SPEC SHEET & DISPLAY

\- Fixed spec sheet fields that were garbled/mistranslated text

\- Corrected the 0-100 km/h figure to the real Sport Chrono time eventhough the 3D model cockpit doesn't feature the SC clock or Sport Response button.

\- Regenerated the in-menu torque/power graph so it now matche the actual physics instead of showing stale numbers

\- Instrument cluster color/brightness tuning refined



CONTENT

\- Added new "Chalk" livery
