I'm gonna tie in all the cars here in this statement:
Over at S2ki.com members who got rid of the s2000 got nc miatas to track
The NC Miata on a track with I/h/e, and suspension is faster than the S2000. Almost the same straight line speed. Yes the Miata is down 80hp but with the engine mods and weight in its advantage it's almost dead even in speed. Miatas of this era actually have the same brakes as the rx-8 which were good for that car, great with a car that weighs 400lbs less
Now add in that the Miata is at the end of its cycle run and these brz/ft86 twins can beat it stock around the track I would think after minor
Mods the brz/ft86 could beat the s2000 around the track
S2000 CR or modded S2000 that's another story but these cars are good. Have small track potential and will be a nice alternative in auto crossing. yy
Remember the ft86/brz can fit wheels in the back and other goods to take to the track
