Ok so im gonna get the 12.19" 4 piston setup for the rear eventually but im going to do the front first, ive found the 12.19" 4 piston kit for the front for around $700. I also really like the the 13" 6 piston kit as well and obviously would like to get that one, but it costs $1800. i know the 4 piston kit is good, but is the 13" 6 piston kit really worth the extra $1100? i mean i could buy both front and rear for cheaper than the 13" kit.

btw im runnin 275's up front and 315's in the rear on a 17" rim if that helps at all
