G-link with 12-200 spring

[fillpot]

Guy's i no this has been touched on a thousand times but im going to order some new springs to lower my car down a little more (69 camaro) and was wondering about some spring suggestions,it has a 12-200 in it now and was leaning toward a 8-200,the car is just street driven and i also do some 1/8 mile drag racing no autocross or anything,car just needs to set a little lower and i've got the shock mounts in the lowest setting.THANKS!
