I really done like my ifs it gets hung up on stuff and i dont have much clearance, also i cant flex that well because it only can go so far down so in some places where you need some flex it jusdt wont cut it! I havent had anyhitng break on mine and i ahve a 4 in suspension and 33's and i run trails with no problems jsut a bent tie rod is all i have come out with no breakage or anyhting! but really a solid axle isnt to bad on street but if compared to ifs there is a difference. If you are jsut gonan wheel it here and there and not tuff trails or anyhitng stick with ifs but if you are gonan wheel like every weekend or somethign like that and its pretty tuff trails swap it so a solid axle i wish i woudla hev done that before i got my lift for my runner!
