*** Genesis Coupe Master Resource List ***
This post will be continuously updated as required. If you have useful resources you'd like me to add, let me know.
Buyer's/New Owner's Guide if you want to buy or have recently purchased a Genesis Coupe, this will quickly get you up to speed on common problems and things to know, look for, or expect.
Shop Manual Downloads the same manuals the Hyundai dealerships have containing everything needed to do just about anything to the cars. Torque specs, fluid types and capacities, troubleshooting procedures, etc. Use the CTRL-F search function in the PDF to find things much easier.
Modding Guide a general guide on how and where to start modding. List may not be fully up to date as it is from the Gencoupe forum and I cannot control that.
How To Fix Common Interior Water Leaks Guide these are super common but easy to fix issues most owners will run into at some point.
How To Improve Shifting On the 6-Speed Manual Transmissions remedies for sloppy, notchy, or difficult to shift transmissions.
Owner's Manual/Service Schedule covers all fluid capacities, types, and maintenance requirements at specific mileage intervals. (*I will need to add some updated pictures from a newer manual soon*)
How To Improve Handling basic guide to handling improvements.
3.8 Timing Components Replacement Guide BK1/BK2 are 99% the same so this guide should cover them both adequately. Save yourself thousands of dollars by doing the work yourself.

Additional Non-Reddit Resources
Genesis Coupe Owners Group contains an enormous amount more information and pictures than Reddit does, especially the pinned posts in the featured section. Join the group by answering all of the membership approval questions that pop up after clicking join, and agree to the group rules. Approval is usually given quickly. Group atmosphere is friendly and informative unlike many other online car groups.
In the featured section of this group you will find other useful posts such as:
The Official Wheel Thread containing many pics and specs of wheels others are running on their Genesis Coupes. These will help you decide what wheels and specs to choose for your own vehicle.
The Official Exhaust Thread with many videos of various exhaust setups to help you decide what exhaust option you should choose for your own vehicle.
The Official Oil Analysis Guide where used oil analysis samples will be consolidated to show data on how specific engine, operating conditions and oil choices fare together regarding the 2.0T and 3.8 Genesis Coupes. This is partially an effort to combat wildly bad oil information commonly spread online. I currently have more samples in the works for a back to back 5w20/5w30/5w40 comparison and will be updating it accordingly.
Other Facebook group include:

Recommended Vendors
OEM parts - Albert Hwang is a very reputable (and most importantly cheap) OEM parts dealer that ships OEM parts quickly and worldwide. Send him a message on Facebook, he is usually quick to respond and you will typically get your parts within a few days. I've personally used him multiple times and cannot recommend him enough. Don't pay dealership prices for OEM parts.
Rockauto.com - always has a large selection and great prices. I suggest ordering things like engine air filters, cabin air filters, and oil filters in bulk from them so you always have spares. OEM oil filters are made by Mahle, it is strongly recommended to stick to OEM filters to reduce startup rattles.
3Point8Performance/380 Performance - worth noting some backorders are taking the large part of a year to fill as of now (Nov 2022)
Uniq Performance (Canada)
ECU Tuning
SFR - I've personally been running a canned stage 1 tune from them in my 2010 3.8 since early 2014 for over 200k miles on the tune alone without issues. Some people say SFR had bad tunes, some don't. Mostly positive reviews, some negative ones.
Alphaspeed - probably the most common these days, usually done by an authorized tuner in your area. Mostly positive reviews as well, but still has some negative ones too.

About time! ;) glad to see you’re a mod now, and this list is very nicely made, thank you!
Thanks. Doing what I can to make the group more informative and useful.
You're more than just another dude, you're an absolute legend mate! Given the somewhat youthfulness/inexperience of the genny community (not throwing shade here, I'm one of these people and i need all the help i can get), your contributions and advice on this sub are incredibly valuable to people like me, so i hope you know how much w'preciate ya!
Well thank ya. To be honest, I just got tired of repeat questions with simple solutions. And I didn’t want to type it out more than once.
