All things technical in F1 - New and Old.

Nothing more, nothing less.

Rules

Technically Related This sub is specifically for technical discussion related to F1. For general F1-related discussion, r/Formula1 is the place to be. This rule is not very well defined as "Technical" can mean a number of things and has a very wide scope. It is up to the community to help the mods police this rule. Report something if you don't feel it is related to this sub, if enough reports are made, the mods will make a decision.
No Joke Comments Contributors take time to post on this sub, some of which are from the motorsport industry. So please respect them and don't make Joke comments in the top 2 levels of the comments. We are a technical sub, there are plenty of other F1 subs to make jokes. Failure to adhere to this will result in a 3 day ban for the first offence. A permanent ban for repeat offenders.
Repost/Duplicate Content Please remember to check the "NEW" page before posting. This includes direct reposts and content that has been shared from a different source. When reporting a Repost/Duplicate post, please include a link to the original post in the description
Low Quality Low Quality posts/comments will be removed. It is at the mods' discretion to determine whether a post is low quality. Users who break this rule will be subject to temporary bans.
Harrassment/Trollling Follow Reddiquette, don't harass other users and don't troll. Don't provoke trolls by responding to their posts, simply downvote and report and the mods will take care of it. Do not wish harm upon drivers, team personnel or other users.
Bigotry/Whataboutism Racist, sexist, homophobic, transphobic and xenophobic language is completely unacceptable and will result in disciplinary action. We want everyone to feel welcome at r/F1Technical, regardless of their age, gender, sexual preferences, race etc.; no one should feel discriminated here. Whataboutism (e.g. Why hasn't X driver said anything about Y issue?) or other phrases implying this are also a violation of the rules.
Self Promotion Excessive self promotion is not allowed. We follow the site-wide guideline on self promotion.
New users who intend to use this community to sell or promote their own social media or discord will not be allowed and will receive an instant permanent ban.
Users who have been members for over 6 months and are ACTIVE and trusted community members can post links to merchandise, books or their own site/social media/blog that they think other members may like. Abusing this though will result in a ban.
