Correct me if I am wrong, I'm sure you will but, there comes a point in horse power where you are gonna start breaking Upper and lower's, axles, gears, transmissions, or what have you. Now I've only read about a hand full of people w/those kind of ponies. The round tubular design is not as strong as a cubed tube desighn, like houses are stronger if they are built on a squared foundation than something round. The Square desighns are heavy thats a major downside but, very very sturdy. So if you are looking for a great setup w/plenty of cash, coilovers back and front, with the aluminum light weight lowers that UPR and or Steeda has, if cash is a issue but, you are not comfortable w/the desighn then go with steedas or Roushes squared desighn, I paid a 158 dollars including shipping, my car feels like it floats on air compared to stock! Just my honest opinion!
