Yes we fitted a set to my brothers truck and the fibreglass was so thing the bolts could not even be snugged up. The rears cracked first then each has hairline cracks throughout. Got them for a box of piss so they have stayed on but will definately be requiring some more fibreglass added to the rear. Also the fit was pretty shocking. They had to have the corners notched and stitched together with cable ties to fit the fronts. They will be sweet though as a basis to refibreglass and the width they give was required for 32x11.5s and -28 offset. Overall since we got them cheap they are good but i imagine plastic would be much better.
They do look awesome though
