Ive got coilovers on the car ive just bought, only realised today

Ive got the urge now that wont go away until i do it to lower it as much as possible whilst still making it driveable, im not sure what coilovers they are, and i have no adjustment tools, on the fronts to make it lower do i wind the adjuster at the bottom upwards on the thread so to compress the spring more?

Now the rears they are independant, seperate shock and spring, the spring in the wishbone has got an adjuster on the bottom of the spring, how do you adjust these? Is there anything i can use or do i need to identify the make of them and then somehow order the correct tool ?
