We Build
Porsches
The Right Way.
IMS bearing. Bore scoring. PDK calibration. Corner weighting. Engine builds. Track prep. We know the platforms, we know the failure modes, and we know what it takes to make a Porsche faster without making it fragile.
Porsche Built the Car Right.
We Just Make It
Go Faster.
Porsche built the car right. The chassis is balanced, the engine placement is intentional, and the factory suspension geometry has more engineering behind it than most shops will ever understand. When a Porsche owner walks into a shop that treats it like a generic European sports car and starts throwing parts at it, the result is usually a car that's worse than stock — just louder and more expensive.
We don't do that. Iron Ridge has built, prepped, and tuned Porsche platforms across the 911, Boxster, and Cayman lineup for over a decade. We know where the M96 is fragile and how to fix it permanently. We know what the GT3 engine wants when you're chasing lap time at COTA. We know the difference between a PDK calibration that transforms the car and one that just changes the shift points.
If you've been looking for a shop in Houston that actually knows your platform, this is that conversation.
Two Families.
Four Generations Each.
We Know Both.
The 911 and the mid-engine Boxster/Cayman share DNA but drive completely differently. Each generation has its own architecture, its own known issues, and its own performance ceiling. Click either card for full generation detail.
The 911 is four generations of development built on the same fundamental concept — rear-engine, rear-wheel drive, and an obsessive refinement of what that means at the limit. Each generation has its own character and its own ceiling. The 996 and 997.1 carry the M96/M97 and the IMS conversation. The 997.2 and beyond introduced the 9A1 direct-injection engine. The 991 GT3 brought the MA1 at 9,000 RPM. The 992 is the current benchmark. We work across all of them.
The mid-engine Porsche is the platform that the track community quietly knows is the better-handling car. Lower center of gravity, perfect weight distribution, and a chassis that rewards driver skill more directly than the 911. The 981 Cayman is one of the most cost-effective track platforms available. The GT4 variants are the factory acknowledging what enthusiasts already knew. The 718 GT4 and Spyder returned to the 4.0-liter MA1 from the GT3 — and they are exceptional.
Six Services.
All In-House.
Every service below is performed in our shop by the same team that tunes the car on the dyno. Nothing farmed out. Click any card for full detail.
Bore Scoring
The two most documented reliability concerns in Porsche's water-cooled era — both solved. The IMS bearing is addressed with the LN Engineering IMS Solution, combined with clutch and rear main seal service in the same appointment. Bore scoring is diagnosed with a borescope and repaired with Nickies nickel-silicon carbide cylinder liners where needed — more durable than the factory Lokasil. We perform the diagnosis honestly and only recommend repairs on cylinders that actually need them. Every service is documented with photos and added to your car's service record.
— Flat-Six
Porsche's naturally aspirated engines are among the most mechanically sophisticated production engines ever made. The MA1 in the GT3 and GT4 revs to 9,000 RPM from the factory. These are not engines to approach carelessly. We build Porsche engines for road use, track use, and racing use — full rebuilds to factory tolerances, upgrades within the factory architecture, and track-oriented builds for cars seeing sustained high-RPM operation that street driving never demands. Every engine leaves the shop dyno-verified with a full build document.
Corner Weighting
A 911's factory suspension is a compromise across daily driving, track days, and road use. For a car that's primarily a track tool, that compromise leaves significant performance on the table. We install and setup coilovers from Öhlins, KW, MCS, and Moton on all Porsche platforms — then align and corner-weight every car before it leaves. Damping is tuned to the specific discipline and driver style. For PASM-equipped cars we advise on delete versus retention based on your specific use case. Correct corner weighting on a 911 makes the rear's limit predictable instead of sudden.
& Transmission
The PDK is one of the best dual-clutch transmissions ever built — and its factory calibration was tuned for emissions, efficiency, and comfort, not for the way you actually want to drive. PDK calibration work covers shift speed at full and partial throttle, launch control behavior, torque management, Sport Plus mode response, and downshift mapping under braking. The goal is a transmission that responds to driver input with precision, not one that second-guesses every request. We also handle G87 manual service, clutch and flywheel builds, and the 986/987 intermediate shaft service.
& PCA
The PCA Gulf Coast Region runs some of the best-organized HPDE events in Texas. We handle pre-event tech prep for first-timers — brake fluid, lug torque, tire inspection, safety check — so your car passes on the first attempt. For drivers moving into wheel-to-wheel competition in PCA Club Racing, NASA, or Global Time Attack, we build to the specific rulebook for the class: cage, harness, fire suppression, safety equipment, and setup that matches the technical requirements. GT4 Clubsport conversions are a specific specialty.
& PCCB Conversion
Porsche PCCB ceramic brakes are superb on track but replacing a set of PCCB rotors costs more than most full big brake conversions. We convert PCCB-equipped cars to conventional high-performance iron rotor setups where the owner wants a more cost-effective track solution. We install Brembo and StopTech big brake kits where the stock rotor sizing is limiting, and spec compounds by discipline — Pagid, Carbotech, and Hawk — selected for the track, temperature, and the car's specific use profile. High-temp fluid spec and full bleed on every brake build.
Known Issues,
Addressed Plainly.
We're a Porsche shop because we've done the work, not because we added a Porsche badge to our website. Here are the platform-specific issues we handle regularly — stated plainly so you know exactly what to ask about when you call.
| Platform | Known Issue | Our Solution |
|---|---|---|
| 996 / 997.1 M96/M97 | IMS Bearing failure — can be catastrophic | LN Engineering IMS Solution + clutch + rear main seal service |
| 996 / 997 M96/M97 | Bore scoring — cylinder wear leading to oil consumption | Borescope diagnosis + Nickies cylinder liner replacement where needed |
| 986 / 987.1 M96/M97 | IMS Bearing (same architecture as 996/997) | Same LN Engineering protocol — combined with clutch service |
| 997.1 3.8 | Rear main seal oil leak | RMS replacement — typically combined with IMS service for efficiency |
| 986 2.5 M96 | AOS (Air-Oil Separator) failure | AOS replacement + full breather system service |
| All PDK-equipped cars | Factory calibration tuned for comfort, not driver response | PDK calibration to shift speed, torque management, and Sport Plus behavior |
| All PASM-equipped cars | Electronic damping compromised for track use | PASM delete or coilover install with proper alignment and corner weight |
| GT3 / GT4 MA1 — track use | Rod bearing wear under sustained high-RPM track loads | Full engine service inspection + rod bearing replacement where indicated |
Why the Houston
Porsche Community
Comes to Iron Ridge.
The PCA Gulf Coast Region is one of the most active Porsche club regions in the country. Drivers here run MSR Houston, travel to COTA, run at Eagles Canyon, and some compete nationally in PCA Club Racing and GT4 Clubsport. The cars get used. That's exactly the kind of owner we want to work with.
We work with drivers at every stage — from the 996 owner who just bought their first Porsche and wants to know what to address first, to the 991 GT3 driver prepping for a season at MSR, to the 981 Cayman owner building a dedicated time attack car. Every stage has the right answer. We know what those answers are.
