**ForceOne’s Tuning Garage!**Open source tunes and more!
Force here, and I have noticed a hole in the community since I began on Forza 4 last February. After a year of playing, I have run a top 100 time on all tracks in A class and set multiple top 10’s in S class as well. I always had decent pace - since I had grown up racing I hit the ground running on the game - but I was clueless, and I bet others have felt the same way. With the inaccuracy of the telemetry and the hundreds of grey areas that arise when tuning cars, I’d like to provide insight and background information on tunes. I’d like to not only share my tunes, but also answer questions regarding why I set things up the way there are.
Sometimes I find that newbies are outcasted from the game, labeled as inexperienced and sporadic when on the track, while ridiculed for not tuning their own cars. I wouldn’t consider myself a top driver yet, although I wish I was, but hopefully I can help at least one person out with the tunes shared below!

If I raced C Class, I could probably set a few number 1’s in this car 
I have tested your S2000 @ COTA, i had to fight this car as it has massive front downforce for a C class car that the rear kept coming around, had to be nearly perfect with out having to push thru the corners that being said i was able to get into the 2:31’s wich is somewhere in the 300’s. It may be more my driving than your tune as i like my tunes with just a bit of understeer. Thanks for sharing.
