well it depends on what you want to do with the coils. From what i've heard Ksport is absolute garbage when it comes to Auto-X or road racing. If you're just looking for a slammed ride they would be fine. the TRD's wont go as low as the Ksports from what i understand. Now if you want to race i'd suggest not getting the Ksports.
