because once you get springs you will realize you didnt go low enough. you will waste 200+ dollars on something you wont even notice and wont feel much of a handling change. coils will give you the biggest change and till you buy new struts, arent all that much more money
This stuff is covered in my FAQ sticky.... "What looks good" is subjective. Now matter how many opinions you have thrown at your, in the end, it's your car.
The benefit of coilovers over lowering springs is yes, height adjustability. If you're not satisfied, you can change it. But you should get an alignment every time you change your height. Because you're toying with your camber/toe/caster settings whenever you raise/lower the car.
I personally think 16" wheels look the best on 6th gen's.
go coilovers you can get progress cs-II's for about 600 dollars, function and form type 1's for about 700 and if you source it right a koni yellow's/ground control spring set for 8-900 bucks. all three of those will be a good set up, lower you at least 2.5 inches and handle very well
