Thank you Nenkai!
 
Can anyone explain DFF and DFR and how it affects the lever ratio? Thanks!
 
Looks like he’s retired…
 
Sorry to revive an older thread, but this proves that I legitimately have so much to learn still (I always will). I spent about the last 3-4 hours wracking my brain trying to understand everything being discussed here. Though it's still surface level, I kinda understand this now. Using this plus an old formula to find spring rate, I managed to shave almost 4 seconds off on Suzuka with the new 992. Stock setup on both runs with the exception of some tuning to the diff. I'm excited to see how much more I can extract from this car once I tune the dampeners and and refine the diff!

Thanks to everyone for sharing their knowledge and to Nenkai for everything he's done + the spreadsheet.

Hey mate,

Get the app that I built using this. www.gtprotune.com

I used this lever ratio and a lot of other real world equations to tune great base tunes.

I've been wanting to check it out, but I don't have any disposable income currently. Plus, I want to learn how to calculate this stuff myself to add to my toolbox.

Okay, it’s a one off cost of $19.99.

Good on you. Have fun.

I didn't realize that it wasn't completely a subscription, that's my bad. It being a one-time purchase is definitely a lot more feasible. Thank you for clearing that up.
