I haven't cut anything from the front of the GX - I've been looking for a front bumper forever for this model ('14+) which is challenging as everything out has its shortcomings. Leaning towards Ironman as the MetalTech version kills me they use zip ties to secure the wheel well liner - that alone is a deal breaker or I'd be running it already.
So basically, just doing the lift gave it a lot of clearance. The skid plates give it protection but the bumper liner on the '14 is huge and contains the grill and everything else as one unit (with a lot of screws and clips), which is annoying vs. the 10-13' model years.
Don't have any pics but can take some if you tell me what you want to see.
No need to go out and take pics, that's the info I wanted. I agree that I haven't seen a 'perfect' bumper out there for the 460 so I was curious what you had done or not. Clearance looks good though, and the overall vehicle looks awesome and capable!
