I have 620's right now that have 1/2 coil cut off. Im running kyb gas adjust. front and rear sway bar 1'. rear mideye leaf springs and shelby drop. rear also has 1' drop. what springs should i run?

 

You want to replace your front 620's with something else? Sorry, but you didn't specify what your looking to achieve...

 

These are the ones I am using
GT coil springs

 

shoot for 80$ ill give them a shot and see how they feel. but do they lower the car at all?

 

no they are stock height. 1/4 coil should get you about 1" but you well need to weight at least a month for the suspension to settle before you get that full 1" drop. Cutting coil springs and using shorter springs is a catch 22 it improves stance but reduces suspension range of motion and stiffens the springs so it has its place but I recommend doing it sparingly. With 620 AND half a coil cut off it is no wonder you are driving a tank. The actual rate of your springs is probably in the 650-675 ranges sense the more you cut the stiffer they get.
