These are bolt on as well, better then the SRT, and cheap is a relative term. Cheaper, yes. but more time has to go into sourcing the parts and if you install it wrong you're SOL. With a kit that is backed by a company with install instructions, if anything fails it's their *** not yours.

I'm all for the DIY mentality, but you can't compare any modification to a DIY project when it starts to effect such things as safety.
