2007 to 2012 Sentra SE-R Spec V suspension

[K1LLA916K]

hey guys i got a question. i like the sentra se-r spec v and am interested in purchasing one. i understand that the stock suspension isnt as good as its competitors because the car is based on a crossover platform. i also think the height of the car is an issue. now i understand that aftermarket performance springs can change that but what i would like to know is which springs are best and have the most comfortable ride? i also would like to know if there are any coilovers that are for street use and also comfortable to ride on. thanks for your input. sincerely, justin timberlake.
