Dont listen to m any local shops around here, trust me. also Nick (norcal trucks) is very knowledgeable, and also many of us on here have done real world testing and racing, vs. 99% of the shops here that just sell stuff out of a catalog.
That is kind of what I figured, bu then 02bigstrokin said he wadded up his econo bars, and that is a little concerning! Although he is drag racing on slicks - something I will likely never do. LOL.
