NOTES: MAKE SURE TO APPLY TUNES TWICE TO ENSURE THAT THEY ARE CORRECTLY INSTALLED! There is a bug that the tune may not be correctly installed if you only apply them once.
Cars/Tunes listed are tested in rivals for laptimes and against unbeatable drivatars to ensure they are performant, tunes will be from me and some of the top tuners in FH5. I aim to have the fastest/best tunes out there for each car on this list with optimal part selection and tuning settings. Tunes will be no aero/stock rims and size if feasible.
Cars/Tunes that are listed as "M/C" (Manual & Clutch Recommended) can still be used with Automatic or Manual, but they will be faster with clutch.
RWD tunes are not recommended for keyboard users due to not having the required throttle control available.
2nd gear launch can help with high-power RWD cars, tapping/feathering the throttle while braking and revmatching on downshifts can help with FWD braking.

Updated my weekly tune post with some tunes worth using for the new seasonal reward car (Subaru SVX) tested by yours truly 👍
Added the correct Celica ST185 tune details for the C class road championship, added another McLaren F1 GT tune for the S1 road championship, added the correct share code for the S1 class Supra RZ tune for the Weekly Forzathon challenge, and new car/tune options for the B class Hot Wheels (CC) championship (B class dirt Subaru SVX tunes can also be used), and the B class road tunes for the Subaru SVX can be used for the Trial (Street) championship as well
