just to name a few... e36/e46 m3s, 350zs (both nismo and track editions), the most discouraging was probably a most likely 4000 lb+ 2002 maserati spyder that looked totally stock slowly walking away from us on a long, sweeping, high speed turn. so no, not necessarily light cars. my car ended up pretty close to the bottom. my azenis had already seen 4 track days prior so they were basically worn down. combined with the greasiness from the heat (90 deg day + sunny) i would feel the car constantly tracking out and undering a bit. throttle steering worked to point the car, but the whole car would kind of just slide to the outside. also we had to be VERY careful as the power was pretty explosive coming in to boost = throttle oversteer + spin out possible at any time.
i have newfound respect for OEM handling cars now. the track we were at is definitely suited for lighter cars, but the cars i mentioned above were probably at least my weight or heavier. tires were a big factor, along with driver skill. granted i had a passenger the whole day (we both weigh a bit over 200lbs each.) in the end, seat time is really the key, and that is tough to keep up with a modified car that is known to produce heat issues. tougher to focus on just driving when you constantly worry about temps, tune, etc. etc. just to be conservative, we were pulling the car in early during all sessions. basically when i saw temps get over 210F water and oil over 240F, i'd try to chill on the car a bit. we werent competitive so it wasnt worth risking anything. i had done a lot of work to the car up to the day before, so nothing had been quite "proven" yet.
