I'm Jonathan — the person who built and maintains this site. If you found something wrong, have a question, or just want to say the accumulator writeup saved your suspension, I'm reachable below.
Anything that doesn't fit below — general questions about the site, suggestions, or just saying hello:
admin@720smanual.comFound a wrong torque spec, a broken diagram, or a procedure that doesn't match what's actually on the car? Please include the document ID (visible in the URL or page header in the SIS) and describe the discrepancy. I take these seriously — bad data on a car like this causes real damage.
admin@720smanual.com — subject: Documentation ErrorFor DMCA takedown requests, copyright concerns, or legal matters, include the specific URL(s) in question and your full contact information. We respond to legitimate requests promptly.
admin@720smanual.com — subject: Legal NoticeFor active diagnosis help, repair questions, and MDS tool support — the right place is the community forum at mcltech.net. There are owners and technicians there who have genuinely seen everything that can go wrong with a 720S. Much faster than waiting on an email from me, and a better answer too.
Before reaching out, these questions come up often enough that the answer is probably already here.
No — the SIS is a web application, not a single document. The original McLaren format is HTML-based with thousands of individual procedure files. There's no single PDF to download. Individual TSBs are available as PDFs from the TSB index page.
Email me with the document ID (shown in the page URL or header within the SIS) and the discrepancy. Include your build date if you have it — some specs changed between early and late production 720S. I'll verify against source data and correct it. Getting the torque values right matters more to me than anything else on this site.
This site covers service documentation only. MDS is the separate dealer diagnostic tool required for ECU programming, calibrations, and adaptations. The community resource for MDS is mcltech.net — that's where to go for the software and support.
The SIS content here is sourced from the 720S Coupe platform documentation. The Spider shares nearly all mechanical and electrical systems with the Coupe — the main differences are roof structure, convertible mechanism, and some body-specific wiring. For the vast majority of powertrain, chassis, and electrical procedures, the documentation applies to both variants.
No. This is an independent community resource built and maintained by a 720S owner. McLaren Automotive Limited has no involvement in this site. All trademarks belong to their respective owners. See the Terms of Use for the full legal disclaimer.
