I run March piggy back style, so I can keep the superior dampening abilitys of the stocker...Steeda, March, ect ALL have smaller dampeners when using a non piggy back style, and they do not function as well. HOWEVER if you MUST pay more, get steeda hands down over anyone else.
But I personally reccomend the March piggy back style....SUPER easy it install and iv never had a problem with anything.
And no, I dont regret the mod at all. But doing it all over again (taken literly) would kill my spirits....I dont think I would touch the car for a LONG time lol. Man that would suck SO bad hahaha.
