I have some Koni coilovers coming next week.
I plan to drop the car about 2 inches.
Will I need a sway/rear bars ?

 

if u like i say get them casue it will help you out so much on handling but u dont have to get them
but why not its like 300 for sways and how much did you coilover kit cost
and your car comes with stock sways already

 

I don't know if it's a "coilover kit" , here :

(the first one, 1000$ not to bad, isn't it ?)

Yep, its a coil-over kit. Is your car a sport edition if so purchase a rear sway bar. If it is not a sport purchase front and rear. You don't have to have them with the coilovers, however the performance will increase.
