i dont know if this has been done yet but heres some tweak sets i made after real cars. they are: chrysler 300c, bmw m3, m6, chevrolet c6 z06, porsche carrera gt, saleen s7tt, infiniti g35, acura rsx, shelby gt500, audi s8, nissan silvia s15, and mitsubishi lancer fq360.
i recommend using the slickmod by kegetys because most of the cars like the s7 for example are too fast for r2 tires so i prefer r1s. for the lancer, g35 etc the r3s and r2s are good also. some cars like the carrera gt and c6 may need practice... the engine performance and gear ratios are pretty much exact but suspension and steering are hard to replicate so expect some oversteer for some cars...(hp/torque @ rpms may be slightly off as lfstweak doesnt allow you to change the position of the power on the rpm range)
anyways....try them out and tell me what you think. if you have any requests i am happy to do more
installation- extract the tweak files into your presets folder and setup files in your data/settings folder

Looks like fun though whatever it is!
