any of the tko's are plenty strong for these light cars, the back tires will brake loose way before any damage to the trans will happen, they are strong,strong,strong!! As far as T-56 6 speed goes, half the time you never use first gear anyway, besides it takes extra HP to turnover the extra gearing. 5-speed the way to go. 428 FE 550 HP Tko 500 3.54 rear with 48,000 mi. never had a problem. Have fun and be safe and don't let it get away from you !
