i dont know about you...but if i spent 250 for an Intake, 500 for exhaust, 1200 for kit, etc, then i wouldnt put some cheap rice crap for 100 bucks. Go with a name brand thats well ENGINEERED, and made with research. If you dont, youll end up with bouncy rides, sag, etc. Think about it.
where are you getting that gold line springs are "rice crap"? cause they are cheaper than a lot of other brands?
