my guess O/S viper; TQ was O/S viper
my preferances are wing 12 O/S viper,Z-28 or Y2K vette by O/s
Viper is faster but a little loose z-28 is more stable not as fast as viper and y2k vette is stuck
GP27 z-28 or y2k vette
Open KOford peugeot
oh and not that i have run INT15 much but O/s Serpent
I my preferances are for .007' bodies they work much better than .010
