Well I'd hate to be the one to say something that gets you into a problem out on the road...
The load limits are often set as much by lawyers as by engineers. I'd be putting out a complete guess here; but If you were to run the suspension and tires at maximum air pressures, you MIGHT be okay...
You didn't say how far over the 525 pound limit you are, and I'm certainly not asking... If it was only a couple of pounds it's obviously going to be different that if you're "A couple more than a couple pounds"... This has to be your call!
The Spyders are a GREAT way to get out into the wind!
