Ive been going back and forth for a while now trying to decide which front lip to go with. Although Ive done more searches than a little bit, I cannot find whether a certain lip is or isnt a bolt-on affair. I prefer the bolt-on, as I had a Comptech ITR lip on my GSR, it wasn't bolt-on and it kept falling off...I guess the double-sided tape wasn't enough. Anyway, the only ones I know of are the OEM and some of the Amuse copies...if anyone else knows of a front lip, not bumper, that bolts on please chime in here...TIA
